At the risk of sounding like an audiophile I noticed that on some bluetooth devices audio quality comes out absolutely terrible (Like radio recorded with a phone microphone). I was using a pair of Bose QC 35 headphones and on my phone they sound just fine but on my desktop which has a cheap $2 bluetooth usb the sound quality is terrible. Ok for $2 what can you expect but now I have a distrust for all bluetooth devices. How can I know if my bluetooth usb is killing the quality of audio when thats not even a listed spec on these devices. I looked in to this a little bit ago and there seem to be a few proprietary extensions to bluetooth that allow lossless streaming but they aren't well supported because they are proprietary. I understand that high quality lossy compression is pretty much the same quality as lossless but how do I find a product that uses high quality lossy compression when it seems some of them use absolutely horrible compression?
