I fly with my phone plugged into my Lightspeed just so I can say and think I'm working, as in if I get a call for a crane job, I can beat feet home and get to my job. My phone for some reason works great with my Lightspeed Zulu3, better then my old Telex ANR, so good that when I first tried it in flight, calling a pilot buddy, we talked for a few minutes and it wasn't until I told him I was flying that he even knew. My bluetooth is always on BTW, as I always have the Sirius radio on, and this is the one damn thing I hate about the Zulu: I can't just plug in an audio cable direct from the sat receiver to the headset. I have to screw around and turn on the bluetooth transmitter, then the bt mode on the headset, and wait until they sync up. Having said that, once I go thru the motions, the sound quality from the Sirius receiver is EXCELLENT. If someone know how i can just plug direct from sat to Zulu, let me know.
