      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.

              these headphones emulate the best in 70's technology. They are heavy. They are hot and make your head sweat. They are not efficient, so driving them with anything other than a very strong audio source results in a relatively quieter response. But it's 2014 and many great advances in earbud and headphone technology have evolved over the last 40 years. Buy something else.

                Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

                Most talk about their wonderful sounding headphones and these do produce excellent sound. However, you notice the bolt on the side, that's what studio used to hang a voice mike. They isolate to allow a singer to listen to the track in his headphones and sing through the mike. My two pair are only 42 years old, so I can't really discuss quality. Frank Sinatra used these in the recording studio. Enough said.

                These cans are the real deal, there's a good reason they have been unchanged since 1970, they are the sm58 of cans, newbies should buy these first so they have a standard to compare to.

                Comments about Koss PRO4AA Noise-Isolating Professional Studio Headphones:

                Good insulating headpones. The vintage design is quite nice, if you like it. Driven by a stereo amplifier performs very well with a precise bass, never booming and a precise midrange and high tones reproduction.
                Also tried with an amateur radio tranceiver and ssb voice and am music listening is quite good.
                Only a word of warning: some portable audio gear may not be suitable to these headphone due their high impedance. Tried with a portable CD player and the volume output was quite low. On other portable gear the volume output was reasonable: i tried with a Samsumg mp3 player and the volume, while not really loud was satisfactory.

                I ordered these headphones because I owned a pair that I bought in the 70's. When they arrived I unpacked them and plugged them into my amplifier. I couldn't hear anything in the left earpiece. I tried them again plugging them into my stereo, still no sound in the left earpiece. I returned them and for a pair of Roland RH 300's.

                    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)
