it's writen on Facebook that it can handle both directions for blutooth.
zero sense?
well make sense to me for smartphone use at least, when you don't want to be wired, and if your smartphone BT doesn't handle apt-x. (which is the case of my samsung galaxy note2)
I could also see myself plugging a Q5 to my pc, and using the the audio jack when I'm sitting at the desk and using BT apt-x out when i'm a couple of feet away. (Yes I could use a 20$ aptx BT usb dongle, but if I can spare myself from buying one.. also usb BT dongles tend to be cpu taxing, which sucks when playing games, the Q5 wilm prolly handle encoding the sound to BT aptx on it's own (if not, I could easily switch from usb to BT to optical/coax to BT woth the Q5), meaning more cpu ressources left to my game)
Indeed, jack of all trade situation, really.
