This one wins when it comes to volume. Every other 'cheap' aftermarket imitation I've used makes it very difficult to hear the other party while contending with highway/road noise (especially the Jabra gel hands free). With the Nokia hands free, I actually had to turn the volume down half way for one of my calls because it was too loud.

Just like any other hands free piece, you will have to treat it gently (I've learned this the hard way). I don't think any of them are designed to handle abuse. Finally - I've had some after market headsets that had problems maintaining good contact with the phone. Only a few locked onto the phone and maintained contact 100% of the time. So far I haven't noticed any problems with Nokia's headset. The round ear bud might not fit everyone, and I haven't tried it on any long phone calls (yet), but it was initially very comfortable (more than the Jabra gel's I've used in the past).

Overall - I am initially very pleased with it.
