To enable LDAC for the A100 on your Andorid device please follow the steps below:
1. Open Bluetooth settings on your Android device.
2. Select the gear icon next to your connected Melomania A100
3. Enable LDAC to enable high quality audio.
Please note that iPhones do not support LDAC. Apple devices use the AAC (Advanced Audio Codec) for Bluetooth audio streaming, which offers excellent sound quality but is not as high-resolution as LDAC. LDAC is a Bluetooth codec developed by Sony that allows for higher bitrates and supports high-resolution audio, but it is not compatible with iPhones.
