Review: Best sounding Bone Conduction Ive heard, but... - 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.
Review: Excellent for the pool! - Love these for swimming laps. 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.

### ⭐⭐⭐⭐⭐ great swim headphones
*by J***N on October 14, 2025*

This headset works exactly as described. Great sound while swimming laps, but sound does improve with provided earplugs. It works so well that I actually had to buy a second one for my wife to swim with, too. The bluetooth connection allows it to function as an external headset for my iPhone, and that seems to also work well. I've used it for five swims without having to charge yet, so battery appears to holding a good charge. Easy to change the volume, and comfortable to wear.
