product description:
Our Design Team puts emphasis on both ergonomic design and user-experience as most important causes.
Unlike most in-ear earbuds which support push-button operation only, KUAK Bluetooth earbuds support all function by touch operations,
which is extremely convenience and more comfortable when you are doing sport, enjoying music, driving or other activities.
KUAK Bluetooth earbuds are also perfect for the active lifestyle, fast movements and high-impact workouts.
The replaceable outer silicone sleeve is slip-resistant and comfortable to fit for all ear sizes.
