<----- I've had to replace my headset recently as it got dropped and the volume increase button stopped working, so now it's permanently stuck on "dead quiet!!".
I really wanted one of these new Razr headsets, but disappointingly, they are not available yet. ----->
Anyway, I got a new one and it arrived yesterday. It's one of these new fangled ones that runs off a single AAA battery. Great idea, but it does make it marginally heavier and it does make your ear sore if you've been wearing it for long periods with the ear piece attached too tightly. The other thing that's slightly irritating is how it handles calls.
My other headset used to "chirp" when it picked up and dropped a signal. Which was really handy if you initiated a call as you could clearly tell the other party had disconnected. This new one doesn't - it rings! It tells you when it's picked up a signal, but bizarrely no indication when the signal has been dropped.
On the plus side it works as well with Skype as the old one, now and again the odd crackle, but not enough to be an issue.
