2.2 Features
2.2.1 Immersive stereo sound and switching between primary/secondary
earbuds
After connecting to a Bluetooth device, the earbuds will play stereo
sound through both channels when making voice calls or playing
music. They intelligently designate one earbud as primary and the
other as secondary based on their condition and battery level.
2.2.2 Feedforward noise cancellation for crystal clear audio
A feedforward microphone is used to pick up background noise, and a
reverse sound wave is generated in real time to eliminate the noise,
bringing comfortable noise canceling.
Maximum noise canceling depth in the core frequency band: 22 dB
2.2.3 Be aware of clear and natural ambient sound
You can switch to Awareness mode by touching and holding either
earbud, which enables you to be aware of the surrounding sound
without taking off your earbuds.
2.2.4 Dual-microphone environmental noise cancellation during calls
Each earbud has two Micro-Electro-Mechanical System (MEMS)
silicon microphones that use beamforming directional sound pickup,
wind-resistant structure, and AI noise canceling technology, effectively
reducing environmental noise to achieve high-quality calls even when
you are walking or running.
2.2.5 Fast charging and long battery life
With a large-capacity battery in a compact body, the HONOR Earbuds
2 Lite feature a long battery life with a low-power solution.
With noise canceling disabled and the volume set to 50%, a full charge
of the earbuds allows for 10 hours of music playback (in AAC format),
or 6.5 hours of voice calls.
A full charge of the earbuds and charging case allows for 32 hours of
music playback, or 20 hours of voice calls.
The earbuds support fast charging, and a 10-minute charge allows for
4 hours of music playback.
(Conditions: The charging case has sufficient battery, the earbuds are
fast-charged at room temperature, and the earbuds are used to play
music in AAC format with a 50% volume level.)
2.2.6 Proximity pairing prompt upon opening the case
On phones running Magic UI 3.0 or later, a proximity pairing prompt
will be displayed each time you open the charging case for a rapid

running Magic UI 4.0 or later.
2.2.10 Convenient settings and updates in the AI Life app
The HONOR Earbuds 2 Lite work in conjunction with the AI Life app
for you to switch between different noise control modes, customize
noise canceling settings, set shortcut operations, and perform OTA
updates.
