What Bluetooth protocols does the POCO X7 support?

The Bluetooth HD audio protocol supports several advanced audio codecs: AAC, LDAC, LHDC 1.0, LHDC 2.0, LHDC 3.0, LHDC 4.0, LHDC 5.0 and ASHA.
For your reference, here is the information about the audio codecs:
1. AAC (Advanced Audio Codec): It is widely used in Apple devices and offers high-quality audio at lower bitrates, making it ideal for wireless audio. It has efficient compression at lower bitrates;
2. LDAC (Low Latency Audio Codec): Developed by Sony, LDAC allows for high-resolution audio streaming over Bluetooth, supporting bitrates up to 990 kbps, which provides better quality than standard Bluetooth audio codecs like SBC;
3. LHDC (Low Latency High Definition Codec): It is a high-definition Bluetooth audio codec designed to provide high-quality sound at low latencies. LHDC 5.0: is the latest version of LHDC.
