Huawei Freebuds Pro 4, Wireless, Calls/Music/Sport/Everyday, 2.07 oz (58.6 g), Headset, Black
Description
Silver Sring Design
Marvel at the laser-engraved handle, a homage to the elegance of string instruments, and delight in the scintillating sounds.
HUAWEI SOUND
Cutting-edge technology recreates authentic sounds
Total immersion in what's meant to be heard
Lossless Sound Quality for Authentic Sounds
HUAWEI FreeBuds Pro 4 is the first pair of earbuds to support 2.3 Mbps lossless transmission,4 thanks to the Huawei-exclusive L2HC 4.0 audio codec5 and upgraded Polar Code technology. HWA Lossless and Hi-Res Wireless Audio certifications mean that this sterling sound really isn't too good to be true!
Tuned by Experts
HUAWEI FreeBuds Pro 4 is tuned by musicians at the Central Conservatory of Music to provide concert-level listening experience, and features two stunning sound effects to capture your imagination.
Classical
Immersive stereo audio effects to create an all-absorbing sound field with every detail.
Clear Calls from Any Place
Calls are crystal clear at wind speeds of up to 10 m/s6 and in situations with noise levels of up to 100 dB,6 such as concerts, live houses, or the metro, thanks to an advanced AI call-noise-cancellation algorithm, with powerful sound pickup made possible by a reverse bone conduction microphone working alongside three other microphones.
Standout Noise Cancellation
Brand new three-layer shape-memory foam ear tips cancel out up to 30% more ambient noise.7 With memory sponge, the ear tips automatically expand to fit your ear canals for a snugger fit.
Tune Out, Tune In
The tip fit test matches the noise cancellation parameters for two types of ear tips. This lets you customise your fit and listening experience while keeping noise at bay—even on flights or high-speed trains—with the help of intelligent dynamic ANC.
Nod to answer phone calls
Answer or reject incoming calls hands-free, just by nodding or shaking your head.
