I think I need to weigh in here in support of my Motorola S805 Bluetooth headphones. I believe I first learned about them in this forum (from Milhouse?) and to me they are great. I listen principally to classical music and their sound quality I find superb. They play both with Bluetooth and alternatively through a headphone cable, and they also can be employed with a mobile phone, as they contain a microphone and an easy switching method to go between listening on the N800 via Kagu or the mobile phone.
