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

Your playlist can come with you into the pool with these SHOKZ OpenSwim Pro wireless sports headphones. They sit on your cheekbones rather than in your ears, sending sound through the bone so your ear canals stay open and you can still hear the lifeguard's whistle or a bike coming up behind you on the towpath. There's 32GB of built-in storage, so you can load up your music and leave your phone in the locker while you swim lengths.

Switch over to Bluetooth for gym sessions or dog walks and you'll get up to 9 hours of playback, with a quick 1.5 hours on charge to fill the battery back up. Built-in mics cut background noise and echo, so calls stay clear even when it's blustery out.
