I don't think it's ADPCM since it sounds really good. I'm not an audiophile or have done any comprehensive testing, but it' the kind of quality a normal person would use for music without complaining.

That was meant to agree with you - AptX is a kind of ADPCM with some other filters added on, so this could be the same thing. That's how it gets low latency.
