Eliminate those cumbersome headphone wires by utilizing RF Headphones. These low-profile headphones are designed to work with the 205_595 RF Headphone System. By working on the VHF Band (194.05), the headphones require no "line of sight" transmission for operation like IR transmitted headphones. Add as many headphones to a system as you like within its operating range. This makes them perfect for mobile video applications. Headphone features: Volume Control, Power Indication Light and On/Off Switch. Requires two AAA batteries (included).
