I operate the headset with a Nokia N95 as an MP3 player and occasional phone calls. The sound when listening to music is quite good, but not top notch. The bass is surprisingly strong. The volume is sufficient for quieter MP3s you would sometimes still want some more juice - but so easy on you his ears little minutely. When comfort you have to get used to something. After a short time hurt my ears - with a little straighten and habituation is but less. The service is really very simple. However, one should be careful with the left button - which is used for A / ARGUS is switched on as well as for call control. Depending on the press to choose the last site called. The key is careful not to use wisely. The quality of the phone's loud statements of my interlocutors good speakerphone accordingly. On my side the interlocutor but listen to a bit dull, which may certainly be due to the sudden change of quality to precisely identify music.
The Ligthshow during playback (the left and right buttons light up softly and regularly) I do not see it myself and find it rather funny. Shutdown can they but apparently not.
What may be due to my phone - when the player is not already running on your phone, the playback does not start automatically.
The connection to my Vista laptop was previously fold only with the bad Mono profile, but not with AD2P. But I have tried only twice.
The association at a BT partner (phone, PC) works well, but the headset will automatically connect only to the last partner.
