Two HP-12S headphones in excellent condition. They were used less than a month for my car's entertainment system. Feature an adjustable swiveling over-the-ear pad to reduce ambient noise. Each HP-12S headphone has independent volume control, channel selector switch, and an auxiliary audio input to directly connect an iPod or other device with headphone output. A hardened plastic carry case is included for protective storage. HP-12S can be used with any mobile entertainment device featuring a dual channel Infra-Red transmitter. Fee Shipping!
