Keep fit without getting tangled up in wires - the Adidas RPD-01 Wireless Bluetooth Sports Earphones feature a neckband with memory wire that means you're able to exercise without restrictions. The in-line controls can adjust volume, skip tracks and answer calls, so you can focus on your workout routine without slowing down to look at your phone. With an IPX4 sweatproof rating, you can keep pushing yourself to your favourite playlist, motivational podcast or workout tunes. You get 12 hours of wire-free listening from a single charge, so no need to take your charger around with you. When they do need a little more power, just 15 minutes charging is enough to give nearly 4 hours listening time.
