Each wireless headset unit has only 3 separate 900 MHz frequency range transmission channels; and therefore interference will likely occur when 7 units are attached to 7 TVs potentially operating simultaneously on 7 different TV channels, all within close proximity.
Sorry, there was a problem. Please try again later.When many Sony MDRRF985RK Headphones are used in the same area, then there will be interference. Also, the Transmitter has only 3 Channels to select from. Therefore, there is a possibility that the other Headphones won’t work with their respective Transmitters.
