Loop High Fidelity Earplugs review

Over the last several years, I’ve noticed a problem developing in my left ear when exposed to continuous loud sounds (it sounds like there is cotton constantly moving around in my ear). I haven’t gone to a doctor about this because it happens infrequently. I’ve tried using inexpensive protective foam earplugs (those intended for use in loud industrial environments) to help with this problem. However, I despise using them because I can’t seem to get a good seal in my ear canal.

When I saw the Loop High Fidelity Earplugs news post on the Gadgeteer, I thought they were attractive and I liked the fact that you can replace the eartips with standard silicone or memory foam eartips. I put in a request to review them and after receiving them and trying them out, I found that I enjoy using them and they help alleviate my problem.

What is it?

The Loop High Fidelity Earplugs are plugs inserted into your ear canals designed to decrease the level of sound when exposed to a loud environment without decreasing the quality of the sound. They come in many colors: Midnight Black, Glorious Gold, Raving Red, Swinging Silver, Flirty Rose Gold, Brilliant Black, Funky Blue, and Electric White.

Design and features

The Loop High Fidelity Earplugs are attractive earplugs made out of a hollow hard plastic material.

Many of the inexpensive protective foam earplugs create a muffled sound because they block your ear canals which act as resonators. To improve the clarity of speech and music and avoid a muffled sound, Loop earplugs use 3D printing technology to create a round compact acoustic hollow channel that mimics the resonator function of your ear canals.

Sound waves enter Loop via a small opening. They then travel through the hollow channel on the inside of Loop. This acoustic resonator has the same length as your ear canal and has a quarter wavelength resonance at 2700 Hz. … At the end of this sound tube we placed an acoustic filter which lowers all frequencies equally. This filter is installed in a laboratory by Dynamic Ear Company. To make sure there are no leaks, they use a UV light technology.” (the Loop website).

In order for the Loop earplugs to work, you must seal your ear canals. The earplugs come with small and medium-sized hybrid silicone tips as well as a pair of Comply memory foam tips. The top of the photo above shows the hybrid silicone tips which, when viewed from the underside, illustrate how the hollow spaces behind the eartips are filled with foam (they are filled with foam from the inner diameter of the tips to the outer diameter of the tips). The eartips are easily attached to the Loop earplugs by pushing and twisting the tips onto the stem of the earplugs.

Use



After receiving the Loop earplugs, I tried using the medium sized silicone tips first, but they were too loose for my ear canals. I needed to use the Comply memory foam eartips to obtain an adequate seal; apparently, even though I am a small person, I have very large ear canals.

Inserting the earplugs into my ears was very easy to do once I figured out the correct orientation. The loop portion of the earplugs should not be oriented in an up or down position relative to the eartips but instead should be oriented horizontally. Once they were inserted, they were very comfortable to wear, although I must admit that I only wore them for about 15 minutes at a time.

I use the Loop earplugs each week when attending our church services. The music is quite loud and when I tested the sound level using the Sound Meter Android app by Abc Apps, the music level hovered around 80 dB. The Loop website states that the earplugs reduce the sound by 20 dB equally across all frequencies. I cannot say how much the sound level decreased when using the earplugs, but it made a significant difference to me and alleviated the issues I’ve been having with my left ear.

Also when using the Loop earplugs, I was unable to differentiate the sound quality of the Loop earplugs versus the inexpensive foam earplugs, but I was still able to hear people talking to me.

Protection

It is also important to note that the inexpensive protective foam earplugs that I’ve used have an ANSI/OSHA noise reduction rating (NRR) of 33 which equates to a 13 dB sound reduction. The Loop website does not state anything about being ANSI/OSHA compliant. It does state that the Loop earplugs are not suitable to use when shooting.

What I like

  • Reduces sound in loud environments
  • Very attractive design
  • Lightweight and comfortable
  • Easy to use
  • Eartips can be replaced using standard silicone eartips or memory foam eartips
  • Comes with nice zippered artificial leather pouch for storage

What needs to be improved

  • A little expensive

Final Thoughts

The Loop High Fidelity Earplug are wonderful to use. I have used inexpensive protective foam earplugs in the past and have so much trouble getting them to fit properly, but the Loop earplugs insert in seconds and fit perfectly and comfortably using the Comply memory foam eartips. They create a great seal and really help to decrease the sound around me when in a loud environment. Would I have purchased them at $29.95? Probably not, but at $20 or less, I definitely would have.

Make your workouts feel like you’re in a video game

Chris Lawhorn sent me an email telling me about his just-released two workout albums that are inspired by the music from video games of the 80’s. The albums feature a collection of mixes where he’s taken beats from 8-bit games to create tracks that will inspire you to run, jump, and avoid bosses (calories). Best of all, all profits from the album go to charity. Lowhorn’s albums are 35minutes each and are selling as a set for $10. You can listen to a couple track snippets and find out more on Run Hundred, a site that helps you discover workout music based on your own favorite tunes.

Dodocool DA106 Hi-Fi Music Player review

“It was the best of times, it was the worst of times.” This quote from Charles Dickens’ Tale of Two Cities pretty much sums up my thoughts on the Dodocool DA106 digital audio player (DAP). Please bear with me as I explain my happiness—and sadness—over this player.

What is it?

Let’s begin with what exactly the Dodocool DA106 player is: The DA106 is a small player that will play music files much like an iPod Nano (remember those?). However, unlike the Nano—or any other iPod or iPhone, the DA106 can play hi-res music files. And it sounds great doing it. Plus, Apple has discontinued all iPods except the Pod Touch, which is basically an iPhone without the phone part.

Design and features

And, oh is it cheap—in price only! The DA106 practically qualifies as an impulse buy. Yet it is built as well and with as many features as players costing much, much more.

The Dodocool (can we change that name?) DA106 is a small, solid aluminum clad player that’s made for people who own their music in the form of ripped CDs and/or digital files. Since it’s a hi-res player, those files can be much higher resolution than what an iPod could ever handle. Higher res files sound better with more dynamic range and richness than any lower res MP3 file ever could. Keep in mind however, that recorded music quality is as dependent on the initial recording as how it’s been ripped or downsampled.

If you’re unsure what I mean by high or low resolution music files, it’s this: Songs bought from iTunes are 256 kbps (kilobits per second). That sounds large until you learn that CD tracks are 1411 kbps—quite a difference. Now people who are serious about digital music prefer even larger files upwards to 2,224 kbps and more. After a while it starts to get a bit silly. Suffice to say that the Dodocool player will play files up to 192kHz/24bit—far higher than a human ear can detect. Confused? Me too, and I understand most of this stuff. All you need to know is that unless you are a hard core audiophile, the DA106 will play anything you can throw at it.

So how does the DA106 perform? That’s an open question, because up until now, nothing—and I mean nothing—equals the ease of use of the original iPod. Even now, iOS and Android aren’t as easy to navigate as the iPod’s original click wheel. The DA106 does have a click wheel that actually spins and clicks when you run your thumb over it. It’s not as smooth as the original iPod’s was. There are buttons next to the small click wheel that brings up File List, Skip Forward and Backward and a separate back button that goes to the previous selection. Apple managed to include these functions on the wheel itself—something that hasn’t been done since the iPod. Maybe Apple has a patent, because no one else is doing it.

But enough comparison griping, because the Dodocool DA106 is one fine music player. It has a dual-core chip with DSD file support (this matters to audiophiles only). It’s solidly built and reassuring in its heft. It has 8gb built-in memory with an additional TF card slot that will accept a 256gb micro SD card. That’s a lot of music storage. There is 30 hours of playing time on a fully recharged battery.

But that’s not all. the DA106 has a built-in FM radio and an internal mic for recording either live voice or FM. If you conduct interviews, the DA106 will record the interview. However, note that there is no port for an external mic.

The DA106’s software is easily understood if a bit rudimentary. The small 2-inch color screen has a resolution of 320×240-pixels—not smart phone quality—but it is easy to navigate and read. That’s good because the included manual is almost useless. It points out what the slots and buttons are for, but that’s it. I learned what was where simply by clicking and scrolling.

The main window gives a choice of Files, Settings, Now Playing, Music, FM and Recording. Music offers more choices, but I mostly use Songs, Artists and Albums. Genres is useless and Storage lists what files are on the main internal memory and what is on the card. In the Now Playing section, there is a built-in equalizer. It’s confusing to use so I just leave it off—something I usually do anyway.

One big pain with the DA106 is that when the screen goes dark to save battery life, no buttons will wake it up—except the power button. Having to press the power button each time just to wake the player up gets old quickly.

So, how does the DA106 sound? Since it’s a high-end player, I decided to pair it with the Audeze iSine10 earphones. Due to their musical accuracy, these planar magnetic wonders will bring out the best—and worst—in music. I’m happy to report that the DA106 works quite well with the iSine10 earphones. The high-res music I loaded sounds natural and transparent. Bass might be considered a bit weak, but it isn’t—it’s just accurate. Anyway, that’s more of a function of the iSine10’s than the DA106.

Note that the iSine10 earphones have to be hardwired to the DA106—there is no Bluetooth. However, there is line-out port next to the headphone jack located at the top of the player. This port allows the DA106 to be connected to an external player (such as a dash-mounted car player) and bypass that players usually inferior amp. Music plays louder when connected this way.

It doesn’t matter what genre of music I listen to with the DA106. It all sounds good, however you’ll get more bang for your buck by listening to higher resolution music files since that’s the reason why the DA106 exists. Lower res MP3s won’t sound any better than they do on your standard smartphone.

Going back to my Tale of Two Cities analogy at the beginning of this review—using the DA106 makes me sad because I keep wondering if the market for stand-alone music players is viable for the long term. As good as some of these players are—and the DA106 is an amazing player—I have never seen anyone on the street using them. Anyone I see listening to music in public is listening from a smartphone—every time. The mantra seems to be convenience over quality. Plus, let’s face it—MP3s and AAC files, Bluetooth and streaming are sounding better and better. Within a few short years, I can’t envision DAPs mattering anymore, except in the expensive and rarified high-end music arena with players costing upwards of $1000 or more. The inexpensive DA106 doesn’t fit into either the convenience or super high-end market.

Positives

  • Well built—as good as players costing much more
  • Solid—aluminum construction
  • Sounds great
  • Very Inexpensive

Negatives

  • Must press power button to wake

Final thoughts

Despite my misgivings about the viability of the DA106’s existence, it is a well built digital audio player that can easily compete with players costing much, much more. So if you’re interested in using something other than your smartphone to house your music collection, the Dodocool DA106 is a great place to start.

Science + music = The Happy Song, to make babies happy (especially over the holidays!!)

“YES!!!!” You say. “I need this! JUST GIVE IT TO ME NOW!!!” Okay, okay! Here are the links to access the song: Amazon Music, iTunesGoogle Music, and Spotify.

For those of you who are curious about the background of the song, while I was reading my Curiosity app (which I LOVE, by the way), I stumbled upon an article on “The Happy Song” that used science and music to create a song to make babies happy. If you are a parent of a baby, you know how valuable that is. When he/she decides to have a meltdown it’s like the ripple effect. The cries emanate 360 degrees from the epicenter and jolt everyone within the audible radius. Some people are understanding while others, not so much. 

At the request of C&G Baby Club, scientists Casper Addyman (lecturer in Developmental Psychology, Goldsmiths, University of London) and Lauren Stewart (music psychologist) were tasked to create a song based on science that babies would like (from theconversation.com).

They found that not much is known about babies’ music preferences, so they started with what they knew the song should incorporate: it should be written in a major key, have a simple repetitive melody, should be upbeat, and have a mother’s sing-song voice. Imogen Heap, the composer who also has an 18 month-old, started with four tunes and decided on a melody that when tested on 26 babies, 20 seemed to enjoy.

The scientists then asked 2500 C&G Baby Club parents to vote on the sounds that made their babies happy. According to theconversation.com,

The top ten sounds included “boo!” (66%), raspberries (57%), sneezing (51%), animal sounds (23%) and baby laughter (28%). We also know babies respond better to “plosive” vocal sounds like “pa” and “ba” compared to “sonorant” sounds like “la”. Heap very cleverly worked many of these elements into the song.

Since happiness is a shared social emotion, the scientists needed something the parents would enjoy too. After some tweaks to the tempo, lyrics, and sound effects, they had their masterpiece. I rather like it. Especially the babies’ laughter.

Perhaps this is just the song you need before embarking on your holiday travels. This one may even make it onto your favorite playlist! Again, it is available on Amazon Music, iTunesGoogle Music, and Spotify. Check out the Youtube link to the song (I love it!):
