I've had several Motorola headsets (HS850, HS810, H700) and none of them seemed to work well consistently with the phones I've had (people always complained that my voice sounded too far away and couldn't hear me). Since I own a Nokia N80 I thought that the Nokia BH-800 would work perfectly with it. Unfortunately, not only do people still complain about barely hearing me, but now I can barely hear people with the volume on maximum! On top of that, if I put my phone in my pocket (same side as the headset) I start to hear static in the headset! Add to this the fact that it doesn't stay in place and always falls out and you have the greatest disappointment ever. This was my first (and probably last) Nokia headset. I love their phones but I'm staying away from their headsets from now on. I thought my Motorolas were bad, but I found something that's even worse. I did however buy the Plantronics Voyager 510 even though I was intimidated by it's large size, it turned out to be very comfortable to wear (actually feels light), the volume is great (I have to keep it on low so I don't hurt my ears), and people can actually here me loud and clear for a change. It also works great with my MacBook Pro and especially with Skype.
