Query: Couldn't Hear Well, Not Sure Why?

I bought this one after my wife already bought another one almost identical to this one at Wal-mart and she really liked it. She used it on our home phone and I was buying this one for her cell phone. She plugged it in and the volume was too low no matter what we changed in the settings. We then switched back to the other head set she bought at Wal-mart and it worked great. I still think, since they are both Plantronics and look identical except for a small on/off button on the one from Amazon, that they would be of the same quality- so it probably was a "lemon" set and wouldn't be typical, unless others have similar problems with this particular model. I sent it back. (Amazon does provide for a very simple and easy return)
