Ordering and shipping were both excellent.I bought The Bose A20, The LightSpeed Zulu and this one. I took them up in the Airplane and tried all 3. The noise cancelling all seemed about the same to me, so I sent the Bose and the Lightspeed back and kept the AVCOMM AC1000 ANR. I have two concerns with this headset. First, it has turned itself off while in flight a few times, but I'm not sure if I bumped the on/off switch, so I will have to try it some more. The other concern is that I am unable to pair the headset with my Android phone. Because of not being able to pair the headset with my phone, I have not tried the Bluetooth, so I can't comment on that. Finally, the headset case should not be a $15.00 add on for a $700.00 headset; it should be included at no charge.
