Incredibly reliable, noise isolating headphones still going strong since 1970.

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 ’80s, 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.

Koss Pro4AAs meet the stringent demands of broadcast and recording professionals who require reliable equipment and superior performance. The full size professional headphones keep unwanted sounds out while letting every note in.

Whether you’re a sound professional or an audiophile, Pro4AAs deliver superior isolation, accurate reproduction and sound intensity, and the excitement of a live performance with every recording. Connecting with your music has never sounded so good.

Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

I've been using these more than 40 years. They DON'T break, they're perfect for recording screaming vocals. Those guys(or Gals)want the track VERY LOUD in their cans so they can shred their lungs & still hear the music. Other headphones always leaked into the recording mic. THESE DON'T no matter how loud you crank them. They have also worked great on recordings requiring a little more finesse (4 voice vocal group tracking live over instrumentals, James Taylor-type singer-songwriters). The high-end clarity and deep bottom end are excellent. I'd recommend them to ANYONE. They're great for listening to music,too. You'll hear things that never came out of your speakers. If you work with them for hours(like I have) they CAN get a little heavy but for unextended periods they are VERY comfortable. Better sound than many more expensive models. Worth every cent. BUY 'EM
(No, I don't work for this company,just love these cans)
