I thought bluetooth was always lossy.

I remember reading there is also a lossfree standard, but as of the last time I've read about it (couple of years ago actually, so the situation today might be completely different) the lossless standard was used by only one or two companies. All others were using lossy ones, which means losing audio information. And as all these compression standards are based on psychoacoustic models, they get rid first of the information that we don't (consciously) hear, so exactly where the good stuff is in subliminal land.
