I find this topic very interesting, if i may add my thoughts.. Well i use A2DP with my phoone, and i enjoy it alot, mine arent nearly as big as moto headsets or anything like that.. but its true.. the quality isnt par to quality wired headphones.. But they are impressive for sure.. And to really think about it, this is fairly new, and not every phone on the market has them. So i think within the next year or so it will improve greatly.. I recommend them, if i want to hear true quality audio then ill listen to my bang & olufsen system. For a quick trip around the block or riding the train its plenty good. just my 2 cents.
