I hav an employer-provided BlackBerry 8700c and a Nokia 6102i for personal use, and I was looking for a headset that would switch easily from one phone to the other. I've had the Scala 700 for about a month, and I couldn't be more pleased with it. It swaps phones quickly, and if I've had my phone off and turn it on, it has reconnected quickly every time.I can hear the person with whom I'm talking better over this headset than I can over either phone, and I've had no complaints about how I sound over it. My wife says that she usually can't tell if I'm on the headset or not.It did take me a couple of days to get the earpiece fixed just right, but after that, a couple of times I have forgotten that I was wearing it till it started to ring.The Cardo Scala 700 has been exactly what I wanted, and quite honestly, it has been much better than I expected from any headset.
