The Huawei FreeBuds SE 4 ANC is a better fit for listeners who prioritize noise cancellation and long battery life over seamless switching between devices. A review published September 20, 2026, describes steady background noise as easier to cancel than voices or wind. Huawei rates the earbuds for up to 10 hours per charge with ANC off, or up to 50 hours with the case.
Huawei FreeBuds SE 4 ANC: the verdict
These earbuds make the most sense if you mainly use one source device at a time and want active noise cancellation (ANC) for steady sounds such as a constant hum. Their biggest everyday drawback is the lack of multipoint: they cannot maintain simultaneous connections to two devices. Hands-on impressions also report that ANC is less effective against voices, wind, and irregular noise than against steady background sound.
What the noise cancellation is rated to do
Huawei specifies an average ANC depth of up to 24 dB across 50 Hz–20 kHz under its stated laboratory settings. That figure describes an average across the specified frequency range, not one uniform result at every frequency.
The product offers three named manual ANC modes: Ultra, General, and Cozy. A Dynamic option appears in the AI Life app as an automatic mode, separate from those three manual choices. In hands-on use, the cancellation is generally reported as more effective against steady noise than against voices or changing sounds.
Battery life by ANC setting
Huawei’s published figures separate runtime on one charge from total listening time using the case. Its Brazil specification table lists the ANC-on figures; actual endurance varies with use.
| ANC setting | Earbuds per charge, up to | Total with case, up to |
| Off | 10 hours | 50 hours |
| On | 7 hours | 35 hours |
The Brazil table’s ANC-on test conditions include AAC playback at 50% volume, wind-noise reduction disabled, and a Huawei Pura 70. The case-inclusive figure is total listening time, not the runtime of a single charge.
Everyday trade-offs: switching, controls, and calls
The FreeBuds SE 4 ANC does not support multipoint, so moving from a phone to a laptop means disconnecting and reconnecting rather than letting both devices stay connected. The earbuds also lack in-ear detection, which would pause playback when an earbud is removed. Hands-on impressions identify limited volume-control options, and the charging case does not support wireless charging.
Huawei lists compatibility with iOS, Android, and EMUI. Its AI Life app provides settings such as ANC controls and equalizer options, though features can vary by phone and region. Hands-on call demonstrations report usable voice pickup with simulated background noise; wind and heavier noise can make calls less clear.
Who should consider them?
Choose the FreeBuds SE 4 ANC if ANC and long rated listening time matter more to you than effortless switching between a phone and computer. If simultaneous connections are a priority, the OnePlus Buds 4 supports dual-device connection and is an alternative to consider.
