Thanks to the technical blessing of LDAC, Sony noise canceling headphones WH- 1000XM3 can listen to lossless music. LDAC is a coding technology, which can transmit high-resolution audio wirelessly (without any frequency reduction and sound quality degradation), transmit data about three times that of ordinary Bluetooth audio (the highest transmission rate is 990Kbps), and enjoy the sound quality of Hi-Res (note: two Bluetooth-connected devices need to support LDAC function at the same time to realize LDAC transmission).

ZX300A adopts a new S-Master HX integrated circuit and adds a 4.4 mm balanced interface. The native DSD format can be played through balanced output (MQA and APE file formats are added), which supports 384KHz/32bit LPCM playback. At the same time, in the aspect of Bluetooth data transmission, it supports Sony LDAC high-resolution Bluetooth coding technology, which is a perfect match with WH- 1000XM3.
