AptxHD is not CD quality. Max is 500 or so bit rate, close but not enough for lossless. Your cans have aptx adaptive which is a bit better but not much and is backwards compatible with older aptX bt codecs. Just not enough bandwidth. You need a better codec headphone+Dac for pure CD, only one being Ldac Sony cans+android or Dac, or straight up cable. For HiFi forget about it over bluetooth.

Bang & olufsens for me. Have the H4s and Portal, light and round cup, low heat retention, nice snug and all that. Really resilient cans too, i’m very destructive. The Sonys XM4s are bit to tight and the ear pads fail every few months (mostly cause of 1 ear removal to hear & amazon pads are thicker=tight snug & hot). B&O lamb leather is really nicezz.
