This version of the H10-20 has a five foot coil cord instead of a straight cord. It is made to work with fixed wing general planes (PJ055 and PJ068 plugs). The noise reduction rating is 24 dB for hearing incoming transmissions clearly, and you have an M-7A microphone (top of the line) for clear outgoing communication.The gel ear seals and cushioned headband are built for comfort.
