The UA True Wireless Streak in-ear headphones were designed together with athletes specially for smaller ears. Their ultra-compact design makes them exceptionally lightweight, plus they are waterproof to IPX7 standards. Control functions for music and calls are triggered by simply tapping the centre buttons. Thanks to the Ambient Aware feature, background noise remains perceptible during outdoor training. TalkThru technology turns down the music and activates noise-cancelling microphones for quick exchanges with a training partner.
