So far I have not been able to get this headset to work with my Nokia 6133 phone. They pair & connect to each other but the phone does not seem to recognize it as a headset. The headset symbol does not come up on the display and the audio is not routed to/from the headset, it stays in the phone. The headset does work properly on a Nokia 8801 and a Motorola RAZR and other headsets will work properly with my phone. This problem has been escalated to Nokia's engineers. I'll post an update here if & when they resolve the problem. Anyone else had any problems using this headset?Also, as for the earloop that comes with it, I could not get it shaped to a comfortable position where it would hook around my ear right. I found that a spare earloop from my Jabra wired headset fit the hole on the Nokia fine and that makes the headset fit much better on me.
