AfterShokz Aeropex Open-Ear Wireless Bone Conduction Headphones With Sport Belt (£150)
"I got the chance to try out these Bluetooth, bone-conduction earphones a few months ago, and I haven't run with anything else since. They sit outside your ear and transmit the sound through your cheekbones (weird, I know), which means you can still hear ambient sounds even with your music playing clearly. As a runner, that increased awareness makes me feel safer and less likely to, say, collide with a bike when I step off the sidewalk for a second. They are comfortable and hold some serious charge (eight hours) for when you're on a long run or just out, about, and away from a plug." — Maggie Ryan, assistant editor, Fitness
