SANSI A21 omni-directional LED light bulb review

REVIEW – When I first started writing for The Gadgeteer, I never in my dreams thought that I would be reviewing light bulbs. And now, I’m reviewing a second one from the same company. But SANSI has good products, and their new A21 LED is lighting my office as I type this. 5000ºK is daylight-bright. I’m finding all sorts of things in here that I’d thought I lost.

What is it?

An omnidirectional light bulb that screws into standard light-bulb sockets and shows your world in a whole different kind of light.

Design and features

When I was assigned the SANSI A21 LED bulb for review, I thought “OK, another LED replacement bulb. No big deal.” When I put this into the regular table lamp in my office and switched it on, however, I was floored. This office has never been this bright. But it’s not a harsh, other-worldly brightness. It just looks like we removed the ceiling and the sun is shining in and lighting everything up, but there are no noon-day shadows. It’s really hard to put into words what it’s like to suddenly have a skylight in a room with no construction.


It’s a light bulb. But it delivers a totally different color and intensity of light than traditional light bulbs, and uses less energy, to boot!

What I like

  • Full-range natural light
  • No warm-up or delay – flip it on, and the sun’s out.
  • Not harsh or overpowering

What needs to be improved

  • You have to start keeping up with the time because it can be full sunlight at 3 AM with this thing!

Final thoughts

$25 per bulb sounds like a lot of money, but this light is so natural and relaxing, you find yourself being more relaxed and calm. I can’t wait for winter now – SAD will not get to me!

Price: $49.99 for a 2-pack

Potensic AW30 (Navigator III) Drone with Camera review

REVIEW – I have been casually shopping for an entry-level camera-equipped quad-copter drone for a year or so. The opportunity to test drive the Potensic AW30 (Navigator III) came at a good time as my sons have recently expressed interest in camera-carrying drones as well. Let’s hope the AW30 fills our needs for a trainer / gateway drone.

What is it?

The Potensic AW30 (a.k.a. Navigator III) is an entry-level drone for kids and beginning enthusiasts. The AW30 packs an onboard WiFi hotspot for relaying images back to a iPhone /iPad or Android device using the company’s proprietary app. It supports video and photo capture and VR display on these devices.

What’s in the box?

The Navigator III arrived in a full color box.

On the inside flap, the charging options are listed (more on this later). No charger is included.

The full kit includes

  • AW30 / Navigator III drone
  • Spare set of propellers
  • Remote control with instructional overlay
  • Phone mount for remote
  • Rechargeable lithium ion battery
  • USB A to micro USB charging cable
  • Multi-language instruction booklet
  • Quick start strip
  • Thank you card

Design and features

The AW30 is similar to other starter drones on the market with fixed position propeller / motor arms, fixed propeller guards, a fixed front-mounted camera, and a removable lithium battery. It includes a remote control which may be used to control the drone or the drone may be flown using the downloadable iOS / Android app. The app supports photo / video capture and live views from the drone’s camera.  The app also supports limited VR capabilities using the appropriate phone mount.

Setup

Setting up the AW30 involved installing the phone holder into the specified slot in the body of the remote and installing 6 AA batteries into the back of the remote.

 

Before flight, the drone’s flight battery must be charged. I used the included cable plugged into a Bestek Vertical Power Cube, which will supply up to 2.4A per USB port based on the demands of the device being charged, to charge the flight battery. Right off the bat, I had trouble getting the cable to seat properly in the battery. When charging the battery has a red LED that lights up. A green LED lights up when the battery is fully charged.

Once charged, the battery is inserted into the bottom rear of the drone (photo shows battery partially inserted).

For the full experience, including video recording and photography requires the downloading of a iOS/Android app to an appropriate device and connecting to the WiFi hotspot in the drone. You must connect to the WiFi hot spot from your device to see live video. The app also includes flight controls that are independent of the remote operating over WiFi.

Before each flight, the drone and remote must be paired and the drone calibrated.

Controls

The controls on the included remote includes two self-centering joysticks and two self-centering toggle switches mounted in the top of the remote in addition to the power button.  The left toggle switch starts/stops video recording if pressed to the left and takes still photos if pressed to the right. The right switch toggles the smart controls, which will allow you to navigate the drone without worrying about what direction it is pointed, when pressed to the left and activates the auto takeoff / landing feature when pressed to the right.

The left joystick controls the altitude and rotation of the drone. The right joystick controls pitch and roll (nose up/down and left/right tilt). The remote will alert the pilot when the drone is flying out of range.

Performance

The piloting experience with the AW30 is much smoother than my last quadcopter. I had previously flown a DraganFlyer III. For those readers not familiar with the older DraganFlyer models, most do not have automatic gyroscopic stabilization or any other flight assistance–you are in complete control, and there is a steep learning curve coming from fixed wing flight.

Flight prep includes

  1. Turning on the remote and then the drone
  2. Pairing the remote and drone
  3. Calibrating the drone
  4. Connecting your phone to the onboard WiFi hotspot (optional)
  5. A quick press of the automatic takeoff button and the drone is airborne

Once in the air, the control trim may need to be adjusted. This is a non-intuitive process that requires using one joystick to go into trim mode and then moving the appropriate joystick to adjust the control trim. This process is much easier using the app controls.

The AW30 is quite nimble and is easy to get moving in any given direction. Like other aircraft and air-cushioned vehicles it doesn’t stop or turn on an dime. I was prepared for this, but the small size of the AW30’s rotors means that it does not respond quickly as vehicles with larger rotors.

My limited time with the AW30 was enjoyable. I was able to successfully fly the AW30 both inside and outdoors without damaging any of the propellers despite quite a few crashes while initially exploring the flight controls and then exploring the flight envelope.

Meltdown

My testing of the AW30 hampered by a battery / cable combination that would disconnect and stop the charging. This seemed to be a problem with the microUSB port in the battery itself. This meant that I would often come back to my workbench to find that the battery had not been charging for the past 2 hours so I had to wait longer to fly again. I was able to temporarily fix this problem by resting the cable and battery at a specific angle while charging.  I also changed to a known-good cable. This worked for several charging sessions. After a test flight one evening, I plugged in the battery into the 2A charger that I had been using and went to have dinner. When I came back the battery was deforming (bubbled) and a strong hot plastic smell, so I quickly disconnected the cable.

We reported this issue to the manufacturer who promised an investigation and sent out a replacement battery. I was in the process of performing a standard out-of-the-box battery top off using a 2A USB charging port and the known-good USB cable. I left the battery sitting on my workbench and walked away to grab a cup of tea. When I returned about 6 minutes later I noticed the hot plastic smell again. When I got over to the battery, the end of the battery had deformed and melted the microUSB plug into the battery charging port. I quickly unplugged the cable from the power supply. After the battery had cooled enough to handle, I examined the battery and cable. After a bit of wiggling, I was able to get the plug loose from the battery, at the cost of the port coming with it. After I separated the port and plug, I was dismayed to discover that the inside of the port was melted.

What I like

Before I had my problems, I was impressed with the

  • Price
  • Ruggedness
  • Support for VR
  • Can operate just from device without need of the remote

What needs to be improved

  • Better quality assurance for the charging cable
  • Much better current / thermal management in the battery
  • Improved trim performance when using the included remote control.

Final thoughts

Initial conclusions

The Potensic Navigator III drone is a fine toy despite the shortcomings in the flight time-to-charging time ratio. However, it shares this same problem with most other small battery-powered quadcopter aircraft. The Navigator III never lived up to the promises of it being a stable video / photo platform, as I could never get the trim dialed in to provide a stable hover, even indoors when our ventilation system wasn’t running. On the plus side, the Navigator III survived many rough “landing” and “encounters” with indoor and outdoor obstacles. The rotor guards protected the rotors from damage, and I’m still using the original rotors after 30 days. The Potensic Navigator III is a good first drone for both kids and enthusiasts to get their feet wet before upgrading to a more expensive and feature-packed aircraft. If you can master stable hovering and control with the Nagivator III, you will have saved yourself lots of trouble and money on replacement parts for your later drones.

Revised conclusions

I cannot recommend the Potensic Navigator III drone due to the persistent issues with safely charging the drone’s batteries. I have had two different batteries self destruct, with the second one taking a USB cable with it.

If Potensic can address the battery charging problem, I will reconsider this statement.

For now, save your money and your safety and steer away from the Potensic Navigator III.

Price: $69.99

AISportage Smart Shoes review

REVIEW – What exactly is a smart shoe? This one is not from Get Smart and does not hide a phone under the heel. It does however have a pocket under the arch for squirreling away some secret tech that could seriously help your running game. Let’s take a closer look.

What is it?

This is a fitness system that includes a smart tracking module, running shoes and smart phone app that work in concert with each other to provide data tracking, analysis and advice.

What’s in the box?

We can’t even discuss what’s inside until we look at this “box”!

Instead of a traditional shoe box, AISportage opted for a tote bag made of two air-filled packaging material sides nested into each other in opposing directions.

It results in a very different and unexpected take on packaging. It’s pretty cool to receive something like this in the mail, but I can imagine this would not work very well at retail. I also question if it is potentially worse than standard box and paper packaging when it comes to recycling.

Inside the packaging  is the pair of running shoes and the accessory box.

Here’s all of what’s in the box

  • AISportage Smart Running Shoes
  • Smart module
  • Charging unit
  • USB-A to USB-Micro charging cable
  • Shoelace module mount
  • Module removal tool
  • Spare laces
  • Instruction manual

Setup

Let’s get this set up…

  1. Insert the smart module into the charger, connect the USB cable to the charger and a wall adapter or computer and let charge until the light turns green.
  2. Install AISportage app by scanning the QR code or searching AISportage in the app store for your device.
  3. Remove smart module from the charger to pair with your phone.
  4. In the bluetooth settings of your device, pair with the smart module that should show up as AIDong ####.
  5. Install the smart module into the right shoe, or into the shoelace module mount.

Here’s how to install into the AIS running shoe.

Under the insole in the right shoe is a small cavity for the smart module. Install the module as shown with LED forward and logo towards the heel. The instructions only show a logo without an LED which doesn’t really help clarify. It kinda fits the other way, but doesn’t fully seat properly.

With the smart module installed go ahead and put the insole back into the shoe and you’re ready to run. You’ll need to remove it periodically for charging and to make that simpler, they included a small prybar tool to pick it out. I was also able to knock it out with a couple of swift thwacks against my other hand.

If you’d prefer to use the module with your own running shoes, you can use the lace attachment that’s included in the accessory box. It’s a silicone type material that stretches into place around the module and has a strap for running securely behind the laces.

Design, features and performance

Just to start things on an honest foot, I’m not a runner. My wife is though and she helped quite a bit in this review. We also both worked at adidas on footwear over 20 years ago and are pretty comfortable with shoe construction and materials.

PART I: Let’s look at the shoe first.

The shoe is built on a standard width last with good quality construction and high quality materials. The upper uses an Air Mesh with non-stretch film heat-pressed or welded to the upper to create a secure cradle around your foot.

On the heel, it’s hard to see past the intel inside™ branding, but there’s a molded heel counter on each side to minimize side-to-side roll as you run. The ankle and achilles area has additional padding as does the upper tongue to create a comfortable fit. Two lace-through guides help to keep the tongue centered.

The bottom has good tread pattern with the blue and black rubbers being different hardnesses for compression and rebound. The blue arch-plate’s X-design allows the shoe’s forefoot and heel to move independently without sacrificing torsional support.

The medial side of the shoe shows the arch support structure of the torsion plate along with the upper’s non-stretch reinforcement.

This image from the company’s website shows a bit more of all the shoe components. AISportage sells the shoe for $70 without the technology. This is a pretty good shoe for that price. More on this in a bit.

PART II: Now let’s look at the smart module part of the system…

The device (on the right) is a simple rectangular module with an LED on the top and 4 contacts on the bottom for interfacing with the charger (on the left).

The charger has 4 pins that mate to the module in a single orientation. There is nothing however to keep you from putting it in backward.

The retention mechanism (lever) does not have a pivot or hinge and instead relies on the material flexibility to deform out of the way during install and removal.

Placing the module in for charging is relatively easy with a positive snap at the end. Retrieving the module however is really difficult. Like break-a-nail difficult as you need to leverage that front edge open to slide the module past.

PART III: App time

After pairing the module to your phone, launch the app and confirm that it has been placed in (or on) the shoe. The center screen above is the home screen and shows your current step count with selections for day, week or month, along with a side scroll sections of calorie, steps, running, cycling and stair metrics that you can click into for more detail. Tapping the upper left sliders icon takes you to the third screen above where you can edit your goal and access settings for firmware updates, device pairing and clear the cache. The app actively counts your steps, but to log a run, you will want to click the pink run circle at the bottom right and choose indoor or outdoor run.

Upon finishing a run and clicking stop in the app, you’re immediately presented with the first screen above. At the top it shows the duration, estimated time for a minute and calories burned. Just below is a very cool spiderweb graph showing balance of forefoot to heel landing and angulation of knee/ankle. It’s then summarized on the next screen (two screenshots above to catch all of the scrolling), but interestingly enough there is no way to find the spider graph again after dismissing it. This was just a quick run, but you can see that I’m a heel striker, with inward angulation that lands with 3 times my weight. In discussing this with my wife, she assured me I would injure myself quickly without learning to transition to more of a forefoot strike.

The screens above are from one of my wife’s runs. As you can see, she lands with more forefoot strikes and the app has advice in multiple areas related to that.

Similarly, the app has details for her on gait as well. The Landing force tidbit above suggests a value ≤ 3 which means I’m in trouble again.

I was excited to find a cycling setting where I could specify bike type. I assumed that it would auto detect a cycling event, but it did not. I’m now guessing that you would also need to click the pink “start run” button and then it would auto-detect that one is cycling due to a lack of any foot strikes.

What’s the takeaway here… I’m struggling a bit with the mix of these products. Data science feels like the main product here in being able to learn about how you run and what you can change to increase performance and reduce strain and injury. There’s a huge benefit to all of that as a stand alone service. The app has a lot of great information and advice, but struggles a bit with navigation and where to find what you’re looking for.

While the shoe is really well made, there are some caveats. One shoe does not fit all runners, although this one should work for anyone in the center of the bell curve. Moreover, left and right feet may have very different strikes and only the right shoe has a cavity for the module. It feels a bit like they needed to make their own shoe to be able to show the value of their module and app. It wouldn’t be surprising as it’s something that many companies have to do; launch hardware in order to ultimately end up as a component or technology vendor within the space they want to be.

It also feels like this would be a product you might use early in your quest to discover and improve your running technique as you’re pretty much guaranteed to have a Fitbit, dedicated running watch, Apple Watch and/or use Strava or Nike Run Club. It’s a tough area to compete in, so maybe they’re looking to break in and end up as a module provider for shoe manufacturers or one of the established wearables. It could explain why there’s no AISportage branding on the shoe, instead choosing to run with a very large ‘intel inside’ logo.

What I like

  • Data collection, analysis and advice of more than steps, distance and route
  • Well made shoe at an affordable price
  • Good value as a package if you’re not duplicating a device or shoe

What needs to be improved

  • Smart module is difficult to install and remove from charger
  • A neutral running shoes may not be the shoe you need
  • Smart module not for sale by itself

Final thoughts

If you’re a runner, you have likely found your way to shoes that work well for your anatomy and running style. From publications like Runner’s World to local running stores that can help you with your gait, strike and other foot positioning, there are multiple ways to get information and help. AISportage has created what may be a great solution for doing that on your time in your own terms. I would hope that they begin offering the technology for sale without the shoe to lower the entry price and help runners hit their stride.

Price: $129 (Currently on sale at $109)

KetoCoach blood ketone meter review

REVIEW – The keto diet – everyone is on it.  Thanks to my loving wife, and my extended middle, as of May 1, I am as well.  I wanted to be able to tell if I am successfully into ketosis, so when the opportunity to test the KetoCoach blood ketone meter came up, I jumped at it.

What is it?

KetoCoach is an FDA-approved blood ketone meter. A blood ketone meter analyzes a small amount of capillary blood looking for ketones.  What are ketones, you say? Ketones are produced when the body burns fat for energy or fuel. They are also produced when you lose weight or if there is not enough insulin to help your body use sugar for energy. Without enough insulin, glucose builds up in the blood. When this occurs, ketones form in the blood and spill into the urine.

Testing for ketones is a primary test for keto dieters and for folks with diabetes. This meter specifically measures beta-hydroxybutyrate (BHB), the most common ketone the body produces. Since the blood cannot get altered as much as urine can, blood is considered a more accurate, and more consistent measurement of ketosis.

What’s in the box?

  • KetoCoach unit
  • Carry case
  • User guide
  • Quick start guide
  • 10 lancets
  • Lancing device
  • Lancet instructions
  • 10 test strips
  • Test strip instructions
  • KetoCoach decal

Hardware specs

  • Test range: 0.1 – 8.0 mmol/L
  • Blood sample size: >= 0.8 microlitres
  • Hematocrit range: 20 – 60%
  • Display: Backlit LCD
  • Memory: 500 tests with date and time
  • Dimensions: 99L x 58w x 16H mm
  • Weight: 49g without batteries
  • Batteries: 2 x CR2032 3v lithium coin cell
  • Battery life: 1000 tests in continuous use or one year
  • Auto power-off: 1.5 minutes of inactivity

Design and features

The unit fits easily in the hand and has a large, easy-to-read display with a backlight for dim conditions. The test strip eject lever is on the right side of the meter. The test strip slot is on top of the meter. Beside the power button are up/down buttons used to cycle through historical tests and also for setting the date and time.  Speaking of setup…

Setup

To power up/down the unit, you hold down the power button for three seconds. When you power up the unit for the first time, it steps you through setting the date and time. Once set, the unit is ready for a test strip.

Performance

To get ready to test, I washed my hands, removed one test strip from its protective foil packet and inserted it into the meter.  The meter powered up and the blood drop icon started flashing above the test strip icon, indicating that the meter is ready for a blood sample.

I popped the top off the supplied lancing tool.  Note that I have the depth set to “1”, the minimum lancing depth. You can vary to a deeper depth, up to “9”, if “1” doesn’t get to your capillaries.  For me, “1” was perfect.

I inserted a lancet into the tool.  Pushing it in automatically cocks the device, getting it ready to stab you. If it doesn’t cock completely, you can slide the large switch to complete the lancet cocking.  That switch also doubles as the lancet ejection switch.

After twisting the protective cover off the lancet and replacing the tool cover, I was ready to pierce my finger. The actual needle is quite thin.

They recommend pushing the tool into the side of your finger to minimize pain. When you’re ready to go, you push the small gray button on the tool.  The lance comes out very quickly and then immediately retracts.

With the thin lances supplied and shallow piercing depth, I didn’t feel anything. When I pulled it away, I could clearly see the indentations of the desensitizing knobs on the tip of the tool.  It is designed to stimulate those nerve endings, minimizing the impact on the nerve endings when the lancet pierces your skin.  It works as I didn’t feel it at all and a small droplet came out.

I touched the droplet to the top of the test strip. The strip is designed to pull the blood in.  As soon as it did, the meter started a countdown of about five seconds.

After the countdown, the meter displays the ketone level in your blood.  I was at 3.3 mmol/L – actually a tad on the high side for ketosis.  This is most likely due to the fact that I was severely limiting my carb intake over the past four days to get into ketosis.  This test indicates that I need to up my carb intake a bit

Just prior to doing this test, I also used a urine ketone test strip.  That test indicated I was really deeply into ketosis.  The blood test backed that up.

About the test strips…in my opinion, they’re costly, but that’s relative.  You have to use the specific one designed for, and available exclusively through KetoCoach.  Per the KetoCoach documentation, others will not work with KetoCoach. They run $34.95 for 50 strips or $0.70 per test.  In addition, you need lancets.  Those cost $9.95 for 100, or $0.10 per test, also from KetoCoach.  That adds up to $0.80 per test. If you regularly test your ketones, that can add up quickly. You can buy generic lancets from your favorite pharmacy or online for as low as $0.04 each, bringing the total cost per test down to $0.74. This price compares favorably with other ketone blood test strips I found on Amazon.  Most run between $0.87 and $1.00 per test, plus the cost of lancets.

Alternatively, you can buy urine-based test strips as low as $0.04 each online from Amazon.  Of course, you have the tradeoff of cost versus accuracy, and there’s no argument that blood ketone testing is more accurate than urine ketone testing. Urine ketone testing is much less invasive. While not as accurate as blood ketone testing, it may be accurate enough.

What I like

  • Easy to use (but not as easy as urine test strips)
  • Accurate
  • Nice carry kit allows you to easily take it with you
  • Low start-up cost

What needs to be improved

  • Cost of test strips is a bit high but is lower than competing brands

Final thoughts

I am pretty impressed with the KetoCoach.  As home-based medical devices go, it is easy to use, and the supplied lancing tool does a good job minimizing the pain usually associated with finger-prick testing. They kept the cost of the required supplies reasonable when compared to competing brands.  When compared to urine-based ketone testing, however, the cost is significantly higher.

So, is it worth it?  That’s up to you.  The initial cost at just under $50 is pretty reasonable.  If the ongoing costs work for you, then getting the accuracy of a blood ketone test at a relatively low cost is a pretty good deal.  Combine that with a good design and easy interface and KetoCoach may be for you.

Price: $49.95

Tao Tronics Headphones review

REVIEW – The appeal of noise canceling/isolating headphones and earphones is increasing as more people listen to personalized audio. Active Noise Cancelling (ANC) headphones are becoming a more popular option as the availability of sound processing technology converges with lower cost and higher demand. The TaoTronics TT-BH046 Hybrid ANC wireless stereo headphones are a new entry into this market. Read on to see what I think!

What sets this item apart is the low sale price of about $90. This is significantly less than the $200 – $500 price of competitive products. The real question about these headphones is how do they compare to the competition? Is this gadget a game changer or pack trailer?

What’s in the box?

  • TaoTronics Hybrid ANC Wireless Headphones
  • USB Charging cable
  • 3.5mm audio cable
  • User guide
  • support contact pamphlet
  • airline headphone adapter
  • carrying case

Design and features

Unboxing

The TaoTronics TT-BH046 Hybrid ANC wireless stereo headphones come in a silver high-quality corrugated box with an image of the side of the headphones printed on the front. The rear of the box lists some of the main features. The box and presentation are suitable for gift giving.

Hardware

The headphones come stored in the carrying case included with the product. The carrying case is zippered on three sides and hinged with fabric on the remaining side.

The case has a shiny textured surface that will stand up to a lot of wear and still look good afterward.

The unit I received is still emblazoned with the existing TaoTronics logo, although units manufactured later will have a newer logo. The new logo is shown on the product registration card included with my sample.

One side of the case is a nylon mesh pocket which can hold the included cables and airplane adapter. The opposite side of the case includes a velcro closure that crosses where the slider attaches to the headband.

The item weight of 7.7 ounces is on the lighter side for ANC wireless headphones. The Sony WH1000XM3 headphones weigh 9 ounces, the Bose QuietComfort 35 II weighs 8.3 ounces, and the Beats Solo³ weighs 7.5 ounces, but are not ANC. The headphones feel very solid; the rotation and extension/retraction of the sliders seems very secure and the cushioning of the headband and ear cups seems very thorough and smooth. The earcups do not rotate freely but have to be pushed around, which appears to make them a more sturdy product. The openings in each earcup are large and I have no trouble fitting my ears into them. The headband sits nicely on the top of my head and due to the lightweight design doesn’t tend to flip forwards or back.

The ear cushions seem soft enough to let the temples of glasses by, but since I don’t wear glasses I can’t be sure, and I cannot verify how glasses would impact the ANC if the earcup seal wasn’t perfect. The headphones do have a couple of design issues that I feel may pose a problem: the steel of the headband seems very sharp behind the imitation leather surrounding the top, uncushioned part of the headband. I wonder if one day it will cut through the imitation leather. Also, the ear cup pivot is only on one side of the cup, and it seems that there is the potential that the plastic or metal may become overstressed where this pivot enters the cup and that the joint may fail. 

 

The headphones look sharp. The metal back to the earcups, with the beveled chrome surround, is a nice touch.

I wonder if this is purely aesthetic or if the added stiffness of the metal is part of the hybrid ANC design or dual speaker design. The plastic parts of the rest of the unit seem untreated after they are cast. The plastic buttons on the earcup look very plain, but at least they do not rattle in place. The bezel around the 3.5mm audio jack is also a nice touch. The inside of the ear cups is a nylon material that is an upgrade from a foam sponge that could be found on lower quality headphones.

Operation

All of the buttons for the system, the 3.5mm input, and the headset microphone (for telephone calls) is on the right earcup. The microUSB input is on the left earcup. The battery is charged in 5 minutes for up to 2 hours of constant use with ANC, or about an hour for a full charge. This 5 minute charge feature is only available with a source greater than 5 Watts (5 v, 1 amp). My measurement of the drawn amperage is about 0.83 amps, so the need for a higher amperage charger is confusing. The headphones don’t come with a charger of their own, but I estimate that most people have 10 or 12 watt chargers available.

The Bluetooth functions of the headphones are controlled using the power and volume buttons. The ANC is operated with a separate switch and switch mounted LED. The Bluetooth is version 4.2 and the headphones support the A2DP, AVRCP  profiles for remote control functionality.  This results in a lot of Bluetooth functionality for 3 total buttons but most are intuitive.

I wish that the redial function was not supported. I have inadvertently dialed my last called number this way; when you butt-dial someone with your head it makes you a…

The type of noise canceling used on these headphones is Hybrid Active Noise Cancelling (HANC) technology.  It takes advantage of a feedforward design that creates a noise canceling waveform based on sounds picked up on the outside of the earcup. It also takes advantage of a feedback design that creates a noise canceling waveform from a sample of the sound inside of the earcups (subtracting the waveform of any music being played). This type of ANC is the most advanced approach available. The execution of this approach depends on the ANC electronics and software. Taotronics claims it can reduce ambient low-frequency sound by up to 96 percent (about 2.5 dB). You can see the mic hole at the top of the ear cup.

The headphones can also be used with a 3.5mm cord and ANC for situations when the Bluetooth radio should not be used (if an airline steward requests you turn off your headphones, legally, you must comply with their request.) If the battery is completely dead then the headphones will still function using the 3.5mm cable.

A nice feature is that if the Bluetooth headphones are not connected to a Bluetooth device for 10 minutes they will shut down.

Performance

It appears that the headphones have two 40 mm drivers on each cup. I wonder what the crossover is between the two speakers because it seems one is entirely for bass boost. Overall I found the listening experience compromising with these headphones. An audiophile would conclude that the sound was muddy and veiled and lacked clarity and presence. Turning on the ANC helped a little bit. I have to guess that some of the muddied sound field may be intentional – like Dolby noise reduction recordings were made on cassette tapes 35 years ago. I listened to Hours from Karakusa by Toshiki Hayashi. Normally, I’m convinced there’s a live bass player on my left shoulder, but not while listening to this. I also listened to the other recordings I used as samples for the V-MODA Forza Metallo Wireless Bluetooth headphone review.  When I listen to Bahia by John Coltrane I can usually feel like I’m listening to a live performance on the upper west side of Broadway, but with the TaoTronics it’s just a recording and not a very crisp one. Listening to There’s No Underwear in Space by The Claypool Lennon Delirium with the Taotronics, the sound of the bow against the bass is muddy and the drums, which are distant to begin with, sound too far away.  The rain at the beginning of La femme d’argent by Air sounds like static and the bass line is too overpowering. The French Suites by Bach played by Murry Perahia is an excellent recording but seems veiled and flat when listening with the TaoTronics. All of these criticisms are made while comparing the sound to some very good alternative headphone and earphones. Using these headphones for daily use, 

The microphone for telephone communication also sounds distant and unclear on the transmitted audio, although the received audio sounds very loud and clear.

The headphones have a fast charge feature. To test this feature I left the headphones on until they were out of juice. Neither the power button not the noise canceling was functioning. I left the headphones alone for a few hours to allow the condition of the battery to normalize. I attached the headphones to a high power charger and the headphones drew only 0.83 amps. I set a timer and charged the headphones for 5 minutes. The tester indicated 69 mAh of charging had occurred.

After charging I immediately started listening to music from my iPhone at 5-6 volume segments (31% to 38% full volume) with the noise canceling on. I got 2:15 minutes of listening before the 20% low battery alarm started.

What I like

  • Low Cost
  • Fast Charge
  • Effective ANC for loud environments

What needs to be improved

  • Sound Quality
  • Cantilevered earbud may break
  • the redial feature is accident prone.

Final thoughts

The TaoTronics TT-BH046 Hybrid ANC wireless stereo headphones provide excellent ANC isolation from your environment, but with average sound quality. With ANC off, the sound is muffled and clogged by heavy bass. Turning ANC on improves the sound, but not enough to recommend using these headphones for serious audio. At this low price, however, these may be the perfect set for commuting on a bus or train.
