Review on Enhanced In-Flight Experience with Sierra ANR Aviation Headset featuring Bluetooth Connectivity by Charles Alvey

The biggest complaint about using a Bluetooth connection to make calls. When using Bluetooth, there is an audio break between speaking and receiving. Loss of connection for 1-2 seconds makes a phone call almost impossible. I had a BluLink adapter that I had used before and it worked great with any headset. Now I connect it to Lightspeed and use BluLink for Bluetooth and Lightspeed for ANR. Better get a non-Bluetooth ANR kit and buy BluLink. At least if you're trying to use your phone at low altitudes. Bluetooth works great for listening to music with the radio turned off.
