I don't like to use them outside the pool because the sound will be pretty soft and trebly. They sound dramatically better when you're wearing earplugs, and even better when you're underwater.Battery live is solid. The only downside is that data transfer is pretty slow, and the controls are a bit awkward. For example, if you want to raise the volume, you press once. But if you press twice, you go to the next folder. So if you want to raise the volume twice, you have to wait a little bit between each press.It took me a while to figure out how to get my playlists playing in the same order. Check the manual, you need to use a certain naming convention for the tracks. ### ⭐⭐⭐⭐⭐ Best sounding Bone Conduction Ive heard, but... *by on Reviewed in the United States August 12, 2025* I tried the Shokz OpenRun Pro 2, and these sound WAY better and play much louder.They sound a lot fuller than the Shokz, with airy highs, natural mids, no tinnyness, and surprising richness in the lows for Bone Conduction.Amd there is actually some bass with these!Be aware that Bone Conduction is never going to sound as good as in ear, on ear, or over ear headphones.But for what they are they are quite good, hence the 5 stars.They also fit with a little more clamping force to ensure good Bone conduction, which wasnt the case with the Shokz on my head.Plus, you get onboard music storage in addition to Bluetooth, and they are fully waterproof for swimming.The drawbacks are, slightly less comfortable and less unobtrusive than the Shokz, and you can really feel the low end physically pulsing into the side of your head, and there is a good but of tickling sensation from the sound vibrations. I didnt have that with the Shokz, but that's obviously the tradeoff for having more volume and more bass.If you might be bothered by the tickling and pulsing sensation, and sound quality is less important to you, then you might prefer the Shokz. ### ⭐⭐⭐⭐⭐ Best value in bone conduction *by on Reviewed in the United States June 10, 2026* I use these swimming, streaming radio and podcasts from a smart watch. There is a known glitch in the instructions about the watch use which the power goes off. The workaround is to start stop and restart.Then it’s fine. I haven’t used the mp3. I use this when working in the yard rather than lose earbuds. These phones are a great value. I didn’t want to spend more money until I knew my methods worked. Battery life is good. The buttons are hard for me to distinguish between the three but others who borrowed had no trouble. Good pairing. Comfortable Fits under swim cap. Ear plugs cuts noise in water and helps with volume. ## Frequently Bought Together - H2O Audio TRI 2 Multisport Waterproof Bone Conduction Open Ear Headphones, Bluetooth 5.3 for Running and Cycling, MP3 Mode for Swimming, 8GB Memory, 8.5-Hour Battery, Black - ZIONOR G1 Polarized Swimming Goggles for Unisex Adult Women Anti Fog 100% Anti UV Diving Goggles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/663647655-tri-2-multisport-waterproof-bone-conduction-open-ear-headphones-bluetooth](https://www.desertcart.pt/products/663647655-tri-2-multisport-waterproof-bone-conduction-open-ear-headphones-bluetooth) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-10*
