Nothing special was required to pair the H375 and the N800. I think the sound is very good. I have used the headset for viewing videos and some of the streaming tv channels discussed in other threads and it was perfectly adequate (although mono of course). I was very happy with the audio performance when using Skype. I also have a Motorola S9 stereo headset that I don't use yet. It works well but only in mono. I am waiting for the A2DP protocol support which is necessary for stereo Bluetooth headsets (hopefully coming soon?).
