Outfitted with Bluetooth 4.0 technology for fast pairing with enabled devices, the XS900 wireless earbuds provide pure, CD-like, high quality sound, with noise-cancellation technology that reduces outside noises and allows clear sound from the integrated microphone. The impressive wireless range lets you use them at a good distance from your smartphone, like during your workout, without dropping the signal. The two powerful audio drivers on each side offer balanced audio and crystal clear sound, for a dynamic and comfortable listening experience, and the comfortable and stable design is perfect for all levels of exercise and activity. With accessible on-ear controls, you can keep moving and keep listening without getting tangled in annoying wires. Designed for hardcore athletes, these earbuds have auricle-shaped ear hooks with rubber coating, so they won't fall out, and will block most outside noise, giving you your personal space in the midst of a crowd, at the gym or on the trail.
