The design of the KEF Motion One Porsche Design not only makes these earbuds modern, but also splash and sweat resistant. This allows you to effortlessly listen to music during rain or when exercising. The neckband keeps the earbuds securely in place. As there's no wire around your body, you have extra room for movement. Connect the earbuds to your smartphone with Bluetooth and stream in aptX quality. That way, you'll feel like you're listening to a CD. The Motion One wireless battery delivers up to 10 hours of uninterrupted listening pleasure, after which the device can be connected using the included audio cable. This way, you can continue listening.
