Mi True Wireless Earphones use a completely wire-free design that unbinds left from right, creating an all new, completely liberated experience when you listen. As small as these earphones are, they pack a sound you’ll have to hear to believe. Break away from the limits of wired earphones. When a phone call comes, simply remove one earphone to automatically switch to single-side talk mode. You can even pass one earphone to a friend to enjoy a song together and bounce along to the beat. Built-in infrared sensors let the earphones know when you are wearing them. You can remove either earphone to pause automatically, so you won’t miss a second of your music or waste battery power. Expect full, wide-spectrum sound and naturally balanced frequency with the 7mm neodymium magnet + titanium plated coil speaker unit. Turn on the noise cancelling mode for an even purer sound experience. Mi True Wireless earphones support AAC codec, which means original sound is more completely restored and vocals won’t blend together with instrumentals. Good music deserves high definition sound. Activate your voice assistant by double-tapping the headphones. Various voice assistant systems are supported. With ENC (environment noise cancellation) technology, your voice assistant will have no trouble hearing you in any environment. After pairing with your device the first time, the earphones will connect automatically whenever you take them out of the charging case. If disconnected, they will reconnect automatically within 30 minutes. After 30 minutes without interaction they will enter sleep mode, but reconnecting is as easy as placing them in your ears.
