Query: Using the headphones correctly, and they do work well

In reading the reviews, I'm thinking some people do not understand how to use them correctly. When I set mine up, you have to have the sound input set very high. This will cut down on the hiss you hear considerably. Also, there is a power saving feature that will cut off the connection when no sound is being inputted into the base station. This is by design, and takes a little getting used to. Once I understood all this, I discovered they work really well.The only thing I do not like is when the unit is in power save mode, and the headphones are on, you will hear a pop type hiss every so often. This is caused by the units attempting to make a connection though the base is in power saving mode. No biggy, but it is something that could have been better engineered. I have a different brand of wireless headphones that do not do this, but they do not have the power save feature.
