Overview

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.

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.

Memories !

By Warren

from Mt. Pleasant, NC

Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

As a Top 40 DJ in the 70's I spent many, many hours with these headphones, so when I tried to fix a cheaper set from another brand and super-glued both thumbs to them, I knew it was time for new headphones. I didn't want any dinky headphones that I could fold up, or trendy designer headphones, I went back to what I knew to be great. When I got them and started listening to albums I've been listening to for 40 years, I heard nuances and sounds I'd NEVER heard before.

Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

Bought these to use while playing the drums. They isolate enough sound, to still hear the music. They do need turned up, and the bass will distort at high volume. Bought these on sale, probably would not pay the MSRP for them.

Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

I had a pair of Koss PRO4A's back in high so I won;t wake up my younger sisters when I played bass or listened to music. Great sound, liquid filled ear covers for excellent noise cancellation. The only thing to be wary of is the size and weight. Try them on first. I am ecstatic to have a new pair.

Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

The earmuffs were too narrow, causing them to crush my ears. They became too painful to wear after about an hour of listening. I did like the sound quality and sturdy construction.
