LDAC high-definition audio can be likened to a "highway" between your phone and earbuds, supporting streaming rates of 990 kbps and a sample rate of 96 kHz with a bit depth of 24-bit. The high transmission bit rate allows high-resolution audio files to be less compressed, retaining more music details and noticeably improving sound quality.
*This high-definition audio requires support from the paired device, and the selected codec needs to be activated on the device to take effect.
For Android phones, first check if LDAC is enabled by default on your phone. If not, go to [Settings > Developer Options] to see if LDAC is supported. If your phone supports it, activate the phone's LDAC and make sure high-definition encoding is turned on in the Nothing X app, thus enabling LDAC high-definition audio encoding.
*To ensure smooth playback of LDAC high-definition audio, it is recommended that when using this feature, 1) the default LDAC playback quality in the developer options is set to adaptive; 2) if the phone chooses a higher quality audio stream, it is advised to turn off dual connection functionality to ensure there is enough bandwidth for the LDAC high-definition stream.
*Since iOS devices only support the AAC Bluetooth high-quality audio codec, for the time being, they cannot support other high-quality audio codecs.
