Pros: AAA battery, long talk and standby time
Cons: disconnect with phone when it's not used(for saving power?)
Summary: when I use it to connect with Ericsson T39, I can hear clearly but the receiver can't hear me. However, I connect it with Motorola E398, it work perfectly!
Using AAA battery let me no need to bring one more charger on my trip!
By the way, I'm looking for a headset which can be connected to both mobile phone and PC, then I can switch between mobile and skype!
