Review on 🎧 H2O Audio Waterproof Bluetooth Wireless Headphones with APTX Audio Stereo Headset, In-Ear Workout Earphones with Built-in Mic for iPhone, Samsung, Android Smart Watch (not Recommended for Swimming) by Brooke Daniels

Very good sound, well designed, they're supposed to be waterproof (note that radio frequencies don't work well underwater so I didn't expect them to work perfectly when I was a lap swimmer), I use them comfortably in my hot tub. They come with a wide range of individual ear tips, so you'll have to work out which one suits you best. Changing them is not the easiest task since they are so small.
