Huawei FreeBuds 4 uses an excellent semi-open ear design, with good ventilation, and brings a more comfortable wearing experience. With Huawei's self-developed in-ear adaptive noise reduction technology, it can moderately reduce external low-frequency noise, making your hearing more comfortable when reducing noise. After turning on noise reduction, the adaptive noise reduction technology can detect your ear canal and match a set of parameters that meet the current ear canal structure and wearing state among multiple sets of noise reduction parameters to optimize the noise reduction experience.
The sound quality of this headset is also very good. It is equipped with a 14.3mm wide-range sounding unit, the sound frequency range is up to 40kHz, the treble is transparent and full, and every note is accurate into the ear. The highly airtight independent sound cavity and the air duct form a low-frequency enhanced engine. The air flowing in the low-frequency engine generates resonance and brings surging bass. At the same time, Huawei FreeBuds 4 is equipped with AEM in-ear adaptive technology, which can automatically detect the shape of the ear canal and wearing shape, and intelligently optimize the audio sound quality according to the detected state, allowing you to enjoy consistent and immersive high-resolution sound quality.
In addition to excellent audio quality, its microphone effect is also very good. Don’t prepare additional microphones, use Huawei FreeBuds 4 with an audio sampling rate of up to 48kHz to achieve high-definition recording.
