When a phone call comes, simply you can remove one earphone to automatically switch to single-side talk mode. You may even pass one earphone to a friend so that he can enjoy a song together and keep bouncing along to the beat. Built-in infrared sensors let the earphones know when you wear them. You are able to remove either earphone to pause automatically, so you would not miss a second of your music or waste battery power. You are allowed to expect full, wide-spectrum sound and naturally balanced frequency with the 7mm neodymium magnet + titanium plated coil speaker unit. You can turn on the noise cancelling mode for an even purer sound experience. Mi True Wireless earphones support AAC codec, so that original sound can be more completely restored and vocals don’t blend together with instrumentals. Good music deserves high definition sound. You can activate your voice assistant by double-tapping the headphones. Various voice assistant systems are been supported. With ENC (environment noise cancellation) technology, your voice assistant has no trouble hearing you in any environment. After pairing with your device the first time, the earphones can connect automatically whenever you are taking them out of the charging case. If they are disconnected, they can reconnect automatically within 30 minutes. After 30 minutes without interaction they can enter sleep mode, but reconnecting can be as easy as placing them in your ears. These come with wireless charging case and 12 hours of battery life.
