This is my first pair of bone conduction headphones. My expectations were not very high, but I figured at the sub-$40 mark it was worth a shot. I would rather be able to hear my surroundings at basically all times and don't have the option of using a speaker in most places.
TL;DR: in a semi-quiet environment (office, home, park), these do EXACTLY what they need to: comfortably for hours at a time, with solid sound quality, and at an amazing price.
SOUND QUALITY:
This is a different experience from headphones or earbuds. If you've ever gone from closed ear headphones to comparable quality open ear headphones, it's a similar amount of difference. The sound comes from nowhere but also everywhere at once. I don't know if this is a positive or negative attribute. I feel like the openness is tricking me into thinking that they have a larger soundstage than they really do, but I can't really compare them to something else because it's just a different feeling altogether.
There's definitely a wide spectrum of overall sound quality depending on the volume they are set at. Not the norm to have such drastic differences when using headphones/earbuds so thought it was worth breaking sound quality out into different zones:
Less than 15% volume: lower frequencies are just completely lost. Alright for podcasts in a very quiet environment, but not much else.
20~65%: the sweet spot. Sound is well balanced and shockingly clear. I'm not an audiophile, but at these volume settings, I would put the audio quality only a little bit below my Anker Soundcore Liberty True (highly rated "value" earbuds). For being pushed in through the side of my face, I was VERY pleasantly surprised. Even the bass sounds great in this range: enough to feel it just a little bit but not enough to tickle.
Above ~70%: not great for music. Once you start getting into this range, the small drivers vibrate pretty hard when trying to pump out bass, and the vibrations themselves muddy all sound (including the bass they're trying to represent). At 70%+ for podcasts/books, they can still tickle from bass vibrations but the sound suffers much less compared to music.
COMFORT/FIT/STAY-PUTTEDNESS
I noticed on day one that I had a headache after approximately 30 minutes of listening at ~40% volume. I left them on and it went away after another ~15m. Hasn't been back after wearing for many hours (and 3+ in a row). There is a mild pressure applied by the spring headband in order for these to actually work, but I got used to it very quickly.
You will not be able to shake these off. I tried to head-bang them loose and they did not move AT. ALL. If you laugh or emote very strongly, you'll notice them shift with you a little bit and the sound will change for a moment, but they find their way right back to neutral when you're done being human. Big plus here compared to in-ear buds that always seem to work their way out when I guffaw at a podcast.
The band, while necessary, is kind of annoying. I'd like to be able to put my head back on the recliner when sitting, but it gets in the way. You may have to adjust your posture depending on your chair. You obviously can't sleep with these on, either. An over-head band style (like headphones) version would be really cool but I don't think those exist.
The weight is less of a problem than I expected. They feel very substantial and significantly heavier than a pair of earbuds, but hooking up over your ears makes for a great anchor point. The band is extremely light (or maybe the fronts are that heavy?) so it never feels like it is trying to tip backwards. The mild pressure exerted on your face helps to support some of the weight as well.
They are still extremely comfortable with thicker-armed plastic-framed glasses: much more than most closed ear headphones, for example. If you move your glasses around they do shift on you. Just like for emoting, though, the driver pads always seem to find their way back to the correct spot and sound returns to normal.
SOFTWARE/BUTTONS:
Buttons are fine, do what they need to. Raised quite a bit, you won't have trouble feeling around for them. There are no buttons symmetrical across the case so it's easy to grab the box and squeeze just one button at a time using the finger space on the opposite side of that button. Takes a rather long hold for power on/off so it shouldn't happen by accident if you toss these in a bag.
Sync happens quickly. Tested on Android/Win10/Linux and no issues so far. One minor downside is the POWER ON, POWER OFF, and CONNECTED announcements are played at max volume every time, which isn't "loud" but does vibrate heavily. I just try to have them off when powering them up/down, you can feel the announcement happen through your fingers when holding them so there's still no guessing.
BATTERY LIFE:
Pretty mediocre, I guess. It would be great to get through 7-8h on one charge for a work day, but it's more like half that at 50% volume. On the other hand, they're cheap enough to buy two and just swap them back and forth if you plan on wearing them for all of your waking hours. I've been charging mine overnight so can't comment on charging speed.

Product Description
A New Way to Listen! Born for Sports!
Bone conduction headphones, a kind of open-ear wireless workout headphones that do not block or cover the ears, so you can enjoy music while staying alert and aware of your surroundings. This unique experience makes them the first choice for exercise earphones because they allow you to power your workouts through music without losing the awareness of your surroundings. This is why runners, skiers, mountain bikers, climbers, and many other outdoor sportsmen and women like bone conduction sport headphones so much.
Bone Conduction Technology
Bone conduction is the transmission of sound vibrations to the inner ear (cochlea) bones of the skull, which allows you to perceive sound without blocking the ear canal. Even more simply put: it’s sound that is delivered directly to the inner ear without needing to pass through the eardrum. Essentially, the vibrations received by the cochlea are the same no matter which way you receive them; they are simply sent via a different pathway.
- Audio enters the transducer;
- Convert sound waves into vibrations;
- Deliver sound straight to your inner ear via vibrations in the bones in your head.
Unique Advantages Of Bone Bonduction Headphones
- Open-ear Safety: Sport Bluetooth headphones leave your ears open and uncovered, which keep you aware of your surroundings and possible hazards, such as traffic, wildlife, and pedestrians; for a safer listening experience. Adding a soundtrack to the world rather than blocking it out, which is a unique, inspiring sensory experience enjoying music safely.
- Comfort & Stability: A lightweight, wraparound titanium frame ensures all-day comfort and a snug fit that will not slip even during strenuous exercise, running, rugged riding, and all other sports that you enjoy!
- Hygiene: There are no ear pods or earbuds inside of your ear canal, which will not make you feel sore, uncomfortable, or sweaty in your ears. This is definitely a big comfort and hygiene win.

MUST WATCH Wireless Bone Conduction Headphones Review
Billy Aiken
There’s really only one thing that I don’t like about it, and it’s that the back of the headphones go about an inch or so out from the back of my head which doesn’t allow for me to wear a hoodie when i’m out in the cold. Other than that though, I love how the headphones sound when working in a loud environment like my workplace. Obviously you need earplugs in which is another reason why this was such a good fit for me since regular headphones noise cancellation while playing music just doesn’t compare. The quality is pretty amazing, too. Though, it takes a couple of hours to get used to the vibrations which allow you to hear the sounds, but they work amazing! Definitely would recommend.
