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.

I have owned these since 1976. I’ve had them refurbished once for $12 by mailing them to Koss HQ, It may be that the warranty has changed, but for a long time Koss has backed some portion of their products with a repair/replacement lifetime protection program for a low fee. Love this company! These headphones were the studio standard back in the day. Nowadays, they are just very good closed ear headphones. Be aware, they are relatively heavy.

I am unspeakably happy these are available again. These are the headphones of which all others are pale imitations. They weigh a ton and squeeze your brains after a few hours, but slip Close to The Edge onto the turntable, turn it up to head-splitting volume, and travel back in time. I've been listening to Koss Pro/4a's since the 70s, and acquired my first Pro/4AA's for a whopping $4 at a yard sale in 1985. They have served me well. Time to retire the old pair and re-invest. You won't regret it.

I have been in radio for over 50 years. I have used Koss PRO4AA headphones for many many many those years. Perhaps since they were first offered. The fit tightly over my ears and I can crank them waaayyyyyyyyyyy up with no feedback while talking on the air. Love 'em!

I used a pair of these back in the 1970s as a radio DJ. Today I'm back on the air and my new Pro 4AAs live up to the quality of my original set.... great phones!

When my vintage set of these died after 50 years, I was heartbroken until I found out that they're back in production to satisfy public outcry. One cannot find a better sounding pair of headphones unless one is prepared to spend many hundreds of dollars more, and only the most highly trained of audiophiles can tell the difference. These earphones are great! The "bang for the buck" can't be surpassed and I highly recommend them.

Love these cans. Comfortable. Great sounding. They have some weight to them, which, to me, gives them a high quality feel. I don't expect to replace these any time soon (I think they'll last forever).
