Soundcore Liberty Air offers both impressive sound and complete freedom from wires. Custom graphene-coated drivers deliver sound with unprecedented clarity and accurate sound reproduction across the entire frequency range. Unlike many truly-wireless earphones, Liberty Air provides in-ear stereo calls. For crystal-clear voice pick-up, the dual-microphones are equipped with uplink noise reduction technology to filter out ambient noise. Calls and music can also be controlled directly from the touchpad on the earbud for ease-of-use. When you take Liberty Air out of the charging case, they automatically turn on and connect to your device. The latest Bluetooth 5.0 technology maintains an ultra-stable connection for skip-free streaming. 5 hours of continuous playtime can be extended by up to 15 hours using the included charging case. Color: White. Gender: unisex.
