Summary: I PREVIOUSLY EXPRESSED MY DISSATISFACTION WITH THIS PRODUCT AND ASKED FOR RETURN AUTHORIZATION. I RECEIVED ADDITIONAL INSTRUCTION FROM QIMING LI, AND WHICH I ATTEMPTED TO GET THE ITEM WORKING TO NO AVAIL. AGAIN, I ASK FOR RETURN AUTORIZATION!!!!
Summary: Has a range of about 10 feet at best. I put the transmitter on top of a large cabinet and the reciever in the room next door, and the sound quality is not very good. In addition to that, transmitter shuts down for no reason now and then.
Summary: I purchased one, it had lots of noise and worse the transmitter power lite would go off and on when this happens you get no sound, I returned that unit and got another, wound up with the same problems. Avoid at all cost!
Summary: As the previous reviewer says the idea is a great one. I bought this speaker for the very same reason. Except that I wanted to take them outside. The range is suppose to be 150 feet, but I guess that must be without any obstacles in its path.
Summary: Just like the reviewer "Ed", my first set "didn't work properly. "They would shut down and not work after a few minutes." I would have to jiggle the power cord to get them to work again. I sent the unit back to Sony.
Summary: Overall they are pretty good. I use them to listen to internet broadcasts from a remote location. You will have to experiment with the location of the sending and receiving units and their placements to get the best sound. It seems they are sensitive to various items, IE pipes, telephones, etc.
Summary: I feel for the price this was a good purchase. It works in the areas in which I was planning to use it. The only problem is the battery will die without warning. Therefore if you are planning to use it for a special occasion make sure the battery is fully charged.
