FWIW I also agree that hardware can definitely affect the quality of a BT headphone. I mean after decompressing apt-x or A2DP/SBC, there's still got to be an amplifier section that can make or break the sound quality. My personal example is my car, which has a spectacular sound system yet manages to ruin BT audio somehow. Without knowing the system architecture, it's not fair to blame the lack of apt-x, but it's all I have to go by as my BT source is apt-x.
