CLEAR CALLS: Your voice will come through clearly when you're on a call. A dedicated mic picks up the sound of your voice while a noise-reduction algorithm reduces some of the background noise from the world around you. POCKET-SIZED CHARGING CASE: The slimline charging case slips easily into a pocket, so you can keep your earbuds protected and charging while you're not using them. Mono mode means you can use either earbud while the other one charges. IPX4 SPLASH/SWEAT RESISTANT: Never mind the weather, an IPX4 rating means these earbuds are splash resistant so they don't mind a little rain! Wearing them during a quick workout or on a particularly hot day? They won't mind a little sweat either. 18 HOURS PLAY TIME WITH CASE: 6 hours play time from a full charge, an extra 12 hours from the case. Fully charge earbuds in the case in 2 hours. Need a quick boost? Just 15 minutes gives you an extra hour. The case can be charged via USB-C. COMFY FIT AND TOUCH CONTROLS: Interchangeable silicone ear tips let you find your perfect fit, resting gently but securely in your ear canal. Touch controls keep things simple. Dynamic bass-boost function, control playback or pick up a call.
