Re: Wireless Speaker Help
If someone else near you also gets 900mhz speakers, headphones, telephone or WI FI, you could get to hear theirs on yours and vice versa. Most have channels you can select to get on a sideband to avoid this but there are a lot of these kinds of things that use this frequency.
My phones are all wireless but I put them on 5.6 ghz so they have greater range and less interference. I also have a set of wireless headphones in the bedroom for late night TV watching so I don't disturb the spousal unit and a couple of pairs or TV video/audio transmitters to beam my Dishnetwork to a couple of TVs that I don't connect to the dish box. (cost savings measure and no wires to run).
Give them a try and see for a couple of days. Keep the boxes in case you need to take them back. Try them out at different times of the day to see if you have any interference. Just realize that someone else can pick up your signal on these and you would not know it. 8)
