Ok, I have only had this headset for about 10 hours, but I have to say I love it! Paired up flawlessly with my Tmobile MDA Music and phone profile work perfectly and all of the controls function as expected. Sound quality it awesome. I've had them on all day and after a few hours my ears do start to hurt, but a little shift fixes it and I think I'll get used to them as I use them.Range from my phone is slightly better than my Cardo Scala 700, which is excellent. I can leave my phone on my desk and walk anywhere on the lower level of my house and stay in range. I expect the range to be even better with my anycom bluetooth dongle.I havent tried using them with my PC yet as I am still waiting for my bluetooth dongle to arrive.
