"Echo problem with Sony Ericsson T616"1.5 starson by CarlZhou
Pros: It works. Easy to setup.
Cons: poor voice quality when using with T616
Summary: I use this system with my Sony Ericssson T616 cellphone. During cell calls, the other party can hear their own voices (echo problem) while can barely hear my voice. I don't have another cellphone model to try. The problem may be just with T616. The customer service people are not aware of such a problem. It seems that I am not alone (please see previous reviews). I believe that the problem may be caused by RF interference.
