Huawei FreeBuds 4i
Huawei FreeBuds 4i is a true wireless stereo earphone that supports new intelligence audio using the ANC that eliminates unwanted environment by identifying unwanted sound waves and creating precisely inverted signals to neutralize the original sound, thereby reducing distracting background noise to the greatest possible extent.
The FreeBuds 4i comes with a 3D bionic design, which fits perfectly and close to the ears that reduce the burden for best comfort. The headsets on both sides have built-in cap active touch sensing devices, which can be controlled by the headset or mobile by either double tap or long-press.
Other features can be set through the AI life application on EMUI 11 or above in smartphones. By double-tapping on left or right earphones, you can play/pause/change music as well as attending the call.
Through the long press, the user can enable or disable the Active Noise Cancellation (ANC), transparent mode or cancel both of these
In terms of battery performance, it packs a 55mAh battery on each earbud and 215mAh on the charging box. On regular use, a user can listen up to 7.5 hours of music with ANC enabled, 10 hours if disabled. The earbuds take at least 60 minutes to 100% charge inside the box and the charging box takes about 90 minutes (22 hours backup support).
Other important features of the FreeBuds 4i includes the wear detection for smart audio interaction and opening and closing detection of the box as well as the earbuds. Moreover, it has Bluetooth 5.2 for faster connectivity
