Shokz OpenSwim Pro Wireless Open-Ear Earbuds - Red, Red

Lengths in the pool, then a trail run afterwards, and this SHOKZ OpenSwim Pro headset comes along for both. It sits on your cheekbones rather than in your ears, sending sound through bone conduction, so you can still hear the lifeguard's whistle or a bike coming up behind you. A triple-sealed body and a breathable membrane over the microphones keep water out, giving it an IP68 rating that holds up to a 2-metre depth for 2 hours.

There's 32GB of onboard storage too, so switch to MP3 mode by holding both buttons and your playlist plays straight from the headset, no phone needed. Handy, since Bluetooth doesn't travel well through water. Prefer streaming on dry land? Bluetooth 5.4 pairs in seconds and gets you up to 9 hours of playback.
