4 in 1 Wireless Receiver & Transmitter

I'm selling a 4 in 1 wireless receiver and transmitter! It can be used as a transmitter to turn a non-wireless TV/PC/Mp3 player into a wireless transmitter. It can also be used as a receiver to turn a non-wireless headphone/speaker into a wireless enabled one and enjoy wireless audio pleasure. It also has hands-free and visual display capabilities
