LDAC high-definition audio can be understood as a "highway" between a mobile phone and Earbuds. It supports a 24-bit bit depth, a 96kHz sampling rate, and a streaming transmission rate of 990kbps. The high transmission bit rate prevents high-resolution audio files from being over-compressed, thus preserving more musical details and significantly improving sound quality.
*This high-definition audio will only take effect if the mobile phone supports it and the selected codec has been enabled on the phone.
For Android phones, first check if your phone has LDAC enabled by default. If not, go to [Settings - Developer Options] to see if LDAC is supported. If your phone supports LDAC, enable it first. Then connect your Earbuds to the Nothing X App, tap Device settings in the App, and then turn on High-quality audio to enable the LDAC high-definition audio codec.
*To ensure the smooth playback of LDAC high-definition audio, it is recommended that when using this feature: 1) In the phone's Developer Options, set the LDAC playback quality to the default adaptive mode; 2) If a higher-quality audio bitstream is selected on the phone, it is recommended to turn off the dual-connection feature to ensure that the LDAC high-definition bitstream has sufficient bandwidth for use.
*Since iOS devices only support the AAC Bluetooth high-quality audio codec, they are temporarily unable to support other high-quality audio codecs.
