In trying to sort out why my Sena SMH10B headset won't carry A2DP (tunes, etc.), I fiddled with playing music via a BlueAnt Q2 headset (it does it in dull, bland, non-exciting mono, of course). While the DINC2 was on my desk, charging as it played music, all was well. Put the DINC2 in its holster and the tunes started to stop (dropouts and even total loss of signal to the point of loosing the BT connection [the Q2 says "there is no phone connected"]). A lot. After a bit of experimentation, it seems that having the DINC2 vertical (in portrait orientation) on my belt means a poor signal to the Q2. Turn the holster so the DINC2 is horizontal (in landscape orientation) and the tunes play just fine. My guess is the BT antenna(s?) are oriented so they radiate in a way that makes the veritcal orientation a problem.
