LHDC 5.0 can be understood as the "highway" between your phone and earbuds. It supports 24 bit/192 kHz high-resolution audio streaming transmission. The transmission rate can reach up to 1 Mbps, which is about 4 times that of the traditional SBC encoder (328Kbps). The high-resolution audio file will not be over-compressed, so more music details can be retained, and the sound quality will be significantly improved.
*High-quality audio settings need to be supported by the phone and the selected codec must be enabled on the phone to take effect.
For Nothing phones, the LHDC Bluetooth audio codec function is turned on by default. After the user connects the headset using Nothing OS, LHDC high-quality Bluetooth audio transmission is enabled by default. Users can operate the headset in the Nothing X app to turn on or off LHDC audio encoding.
For non-Nothing Android phones, you can check whether the phone supports LHDC in the Bluetooth Audio Codec settings of the phone. If the phone supports it, turn on the phone's LHDC in the settings and confirm that LHDC is checked in the HD encoding options of the Nothing X app. LHDC high-quality Bluetooth audio transmission will be turned on.
*To ensure smooth playback of LHDC high-definition audio, it is recommended to turn off the Dual Connection function when using this function to ensure sufficient bandwidth for the LHDC high-definition stream.
*Since iOS devices only support the AAC Bluetooth codec, other high-quality audio codecs are not currently supported.
