It was weird but as I was in the kitchen talking away, wearing the headset while the phone was on the kitchen counter. Reheating my dinner! but anyways I was standing maybe 5 feet away from the microwave and my bluetooth phone was on the kitchen counter about 8 feet away from the microwave. What I would get is a dropped link between the phone and the headset, and the phone would then say continue call so i then picked up the handset and continued talking.
Obviously we can't change channels on a bluetooth device. But I on a similar note I setup a wireless lan for a customer and everytime he would surf on his laptop and would be on the phone (2.4) it would drop his connection to the ap sitting in the other room. So all I did was change the channel of the phone and it was working. Obviously I told him that these two devices will or may interfere in the future. So we moved the ap as far as away from the base station of the phone and i told him to use certain channels after playing with it for a bit.

Believe it or not the BreezeCom DS.11's would _shutdown_ (ie: stop transmission altogether) in the presence of the 1 watt FCC permitted microwave leakage. I verified this using a spectrum analyzer. I have an old Radar Range that I use for 'testing' as the chamber is large enough to act as a mini faraday cage for low output 2.4GHz devices. When I use it to make my daily pot of tea, it puts out the cleanest 2.443 Ghz carrier I have ever seen. But when that was turned on, the DS.11 would stop transmitting no matter what channel it was on. The AP was 14 feet to the right and behind the microwave. I don't know if anyone else has ever looked various microwaves with a spectrum analyzer but most of them spew square wave modulated RF up and down the 2.4Ghz band, and a little above and below as well depending on how cheap of a brand microwave you have. That is the first instance I have heard of a microwave knocking out a bluetooth link. Does this happen whe you are activating the microwave where you are standing in front of it and the laptop is across the room? If that is the case, then the microwave is just literally jamming your headset when the distance between you and the laptop is greater than the distance between you and the microwave.
