HuaweiFreeBuds Pro 4

About

HUAWEI FreeBuds Pro 4, the first HUAWEI Sound earbuds, improves on transmission, noise cancellation, calls, and intelligent experience; while collaborating with acoustic experts to immerse in the sound wave journey with acoustic aesthetics.

Product Features

• Dual-driver True Sound : HUAWEI FreeBuds Pro 4 is the first earbuds to support: 2.3 Mbps lossless transmission and 48 kHz / 24-bit lossless audio. HWA Lossless and Hi-Res Wireless Audio certifications mean that this sterling sound really isn't too good to be true!
• Stable & Clear Calls : Enjoy ultimate privacy wherever you make calls are crystal clear, even at wind speeds of up to 10 m/s or in situations with noise levels of up to 100 dB. Such as concerts, KTVs, or even the metro.
• Intelligent Dynamic ANC: You can customize your fit and listening experience while keeping noise at bay-even on flights or high-speed trains-with the help of intelligent dynamic ANC.
• Silver String Design: The laser-engraved handle, a homage to the elegance of string instruments, and delight in the scintillating sounds. Ceramic DECO features laser-engraved silver strings with a glossy finish that's comfortable to touch.
• Head Motion Controls: Incoming calls, nod to answer. Answer or reject incoming calls hands-free, just by nodding or shaking your head.
• Dual-device Connection: Regardless of whether you're using iOS, Android, or Windows devices, connect to two of these devices at the same time and switch audio between them automatically. When the earbuds are connected to EMUI devices, you can switch audio between more than two devices.
