Product Description

Koss Pro4AA headphones set the standard for full size professional headphones. They were introduced in 1970 as the first dynamic headphones to deliver true full frequency and high fidelity performance with impressive noise isolating capabilities.

Retired in the late 80's, Koss swiftly returned the Pro4AA headphones to its product lineup due to overwhelming popular demand. They have since remained a staple of studio headphones in the radio and recording industries.

Product Reviews

  • "Nice cans for more than 40 years" by mrognstad on 8/12/2014
    Overall: 5 out of 5

    I've had a pair of these since the early 70's, and liked the sound. One side went out, and Koss covered it under their lifetime warranty - only $9 for shipping. Good sealing around the ears for isolation from ambient noise - only problem is my ears get hot after an hour or so. That little silver knob on one side is for mounting a boom mic - unfortunately no longer available.
