Why do multiple sets of wireless headphones cut in and out?

Question

I have four sets of wireless headphones from RadioShack, all the same make/model. I have one base station plugged into the television. All four headsets are set to the same channel (of the 3 options I have, they are all on channel 1).

Why is it that when I turn on more than one headset at the same time, the ones that are on experience periodic though frequent distortions, including a complete drop in sound? I'm no physicist, but it occurs to me that if I yell something, one person hearing that yell does not limit how loudly another might hear it. Why would multiple headphones therefore cause interference with one another?

Answer 1

it's signal interference , you bought the same model they keep picking up each other signals no matter what their settinf is , try to look for diffrent models that run on diffrent signals.

Answer 2

because they work at the same frecuency, try using diferent channels for every headphones or find another equipment to do the same as the base, but with better capacity
