Hi Hassan,

Just wondering if you've ever managed to figure out the right answer? My own research suggests AptX codec is advertised as 0xFF 0x004F 0x01 while AptX-HD is advertised as 0xFF 0x00D7 0x24, so it looks like your earphones only support the former one. A table with several codec IDs can be found here (~60% down): https://habr.com/en/post/456182/

HTH.

Thanks & Regards,

D.
