The Huawei FreeBuds 3i earphones have tapered silicone tips that fit securely in your ears, so you can block out ambient noise and listen with fewer distractions. The earphones adopt a 10 mm-diameter dynamic driver acoustic design and 3-mic noise reduction to ensure high audio quality during calls. Powerful active noise cancelling makes it easy to take control simply tap an earbud to cut out chatter when you're in a cafe, or block background hum on buses and planes. Answer calls hands-free with the 3 integrated mics. Their clever design shields them from wind and noise, so everything you say will sound clearer. The earphones play stereo sound on both channels during voice calls or when playing music. With built-in capacitive touch sensors on both earphones, you can double-tap or press and hold an earphone to operate your earphones/phones. The double-tap operation settings can be configured in the AI Life app, or on a phone running Emui 10.0.1.150 or later.
