The Xiaomi Buds 4, released in December last year, is the world’s first TWS headphones to support LHDC 5.0, with a sampling rate of up to 192kz, which allows you to experience QQ Music’s “mastering” 24bit/192kHz high-quality audio, and is said to have no impact on any of the audio quality even if it is transmitted “wirelessly”. It is claimed that even “wireless” transmission will not cause any loss of sound quality and distortion due to any downsampling process.
