If you don't care about latency, like listening to music or watching a movie, Bluetooth audio can be as good as wired. The maximum bandwidth for Bluetooth audio is 576kbps (aptX HD) which is way above the point at which you can tell the difference.

On the other hand, if latency is important, like on a call, then you can get kind of reasonable latency if you almost give up on quality (34ms from aptX Low Latency) But you're much better off sticking with wired (low single digit milliseconds) since latency matters so much for good conversation.
