I waited over a month to write a review because I wanted to make this review was useful. I bought this specifically for swimming while I do my laps in the pool. I've had a few pairs in the past of the in-ear variety, but ultimately, they never seemed to stay in your ear and once they fell out, you could never get them to stay in again because I guess the suction was now lost that it was wet (I'm guessing). So, fast forward and I started swimming again and although I still had the old headset, I decided to look for something new. I was intrigued by this Bone Conduction, so I took a leap of faith to see how well they worked and this model was more reasonably priced compared to some other brands, so if it didn't work well, it was less dollars spent. I was pleasantly surprised as they work great. They stay on my head no problem. One thing that it does not have is a shuffle feature and I thought that was a negative since I put my files in albums and would normally just have a mish-mash of stuff playing. After using it for a while, I actually found that I didn't really miss the shuffle feature, and I'm sure if I really wanted to, I could have curated my music in a certain way, but I'm really not into that.I've already recommended this product to a couple of people now. I had it with me, so they were able to try before they buy.Also, sound is good. I think better in the water, definitely becomes louder although it's not like I'm blasting them and do not have on the highest volume. Maybe the conduction of sound travels better in water than air.
