Hi,Hi, @DC87 I just tried the AirPods Max owned by a friend and connected to his iPhone, I played some songs I know well. Didn't bother to pair with my Android phone, because I was just curious about the sound. I wouldn't stress too much about codecs though. Apple's AAC is perfectly fine and if it works on Android without issues, is ok. But there are other aspects and features that only work with an apple device.
Recently, I had a chance to try out AirPods Max and compare it with PX7, too. On my Android phone both were nearly on the same level. But on the iPhone (12 Pro), PX7 sounded way better than AirPods for my taste...
