I have used 2-BH-101 headsets, and 1-BH-703 headset to pair with the N810 WiMax. The results are about the same. They pair and work on the first attempt, and after that the device is recognized, but it wont allow for sound. I think there is some sort a code issue in the driver that is getting stuck. I am totally lost as to what to do. Hope there is a solution that is feasable. Otherwise, I will have to walk around with wires around my neck. Wish I had the answer. Patiently waiting.
