Auscultadores Huawei Freebuds Pro 4

Marvel at the laser-engraved handle inspired by string instruments and enjoy refined sound reproduction with HUAWEI FreeBuds Pro 4. These earbuds support high-bandwidth lossless transmission and use the L2HC 4.0 audio codec together with upgraded Polar Code technology to deliver clear, detailed audio. Tuned by musicians at the Central Conservatory of Music, the earbuds offer concert-level listening and two distinct sound profiles, while integrated microphones and AI algorithms ensure clear calls even in noisy environments.

Advantages

Supports 2.3 Mbps lossless transmission and holds HWA Lossless and Hi-Res Wireless Audio certifications for accurate sound. Expert tuning provides immersive stereo and classical sound effects. Advanced call-noise-cancellation combines a reverse bone-conduction microphone with three additional microphones and AI processing to keep voices clear in wind or loud venues. New three-layer shape-memory foam ear tips improve passive noise reduction and fit comfort, and intelligent dynamic ANC adapts to environments. Hands-free call control is available via nod or head shake gestures.

How to use

Fit the earbuds with the supplied three-layer shape-memory foam tips and perform the tip fit test to match noise-cancellation parameters. Use the device source supporting L2HC 4.0 and high-bandwidth transmission to benefit from lossless audio. During calls, allow the microphones and AI noise-cancellation to operate automatically; in noisy or windy conditions the system prioritizes voice pickup. Use nodding or head shaking gestures to answer or reject incoming calls hands-free.

Recommendations

For best audio quality, pair the FreeBuds Pro 4 with a source device that supports high-resolution wireless audio and enable the tip fit test to optimise ANC. Replace ear tips if they lose elasticity to maintain passive noise reduction and secure fit.
