Data comes from Huawei lab tests. A prototype of FreeBuds SE 3 and its corresponding software were tested with a HUAWEI P50 Pro running Harmony OS 3.0 and its corresponding software.
Note: The battery life data of audio playback comes from Huawei lab tests. During the tests, AAC format audio was played at 50% volume level. The default settings were used for other features. Actual results may vary depending on the volume, audio source, environmental interference, product features, auxiliary devices, system, and usage habits.
Note: The battery life data of calling comes from Huawei lab tests. During the tests, a phone call was made at 50% volume level. The default settings were used for other features. Actual results may vary depending on the volume, environmental interference, product features, auxiliary devices, system, and usage habits.

Call quality    The earbuds come equipped with a microphone, and third-party deep neutral network (DNN) algorithm, to generate crystal clear calling at wind speeds of up to 2 m/s. Thanks to windproof structural design and AI noise cancellation, when you are making calls, the ambient noise is suppressed while your voice is enhanced, so that the call remains clear to both parties, even in noisy environments.
