  • Summary: I used these phones from 1977 till 1987 and beyond. I assume the original owner still has them. They were used to record and mix tracks in our small studio along with some other types. These were the favorites. They isolated you from room noise and they didn't lie. For the money and considering their anvil-like construction it was a fine deal. I hope Koss still uses the same materials and methods..
  • Pros: Rugged, good sound, neutral, good isolation
  • Cons: Heavy, sonically flat, can be uncomfortable...

Good Classic Cans

  • Summary: I have owned multiple KOSS Pro 4/AA headphones over the years. The Original high power, high volume, super durable headphones from the 1970s - there is a reason they still make them. The Good: They provide good, solid, clear communications audio. Compared to audiophile headphones, and with most consumer grade headphones, they are a bit light on bass, which is ideal for communications grade audio. The high end is more than ample to the task.

  • Summary: I'm a DJ on a Morning Show. The ONLY issue I have is they weigh a ton, and with them on my head for long periods of time, they can cause discomfort. Duh, take them off. It's just a habit you have to get into....but the sound quality is worth the discomfort.
  • Pros: Isolation, Sound Quality
  • Cons: Weight

  • Summary: I inherited this pair of Pro4AAs from my Great Grandfather who bought them back in the '70s, and they've been working well ever since. They are certainly some of the best sounding headphones that I have ever used, with full response even down to 20 Hz. I lost audio in one of the earpieces, and had to send them in to Koss for repairs, then had to send them back a second time as they broke right after I took them out of the return box.
  • Pros: Audio quality, frequency range, build quality, cable length, lifetime warranty
  • Cons: Weight, tightness on ears, wiring

  • Summary: I have both the 4 A and 4AA both are simply a great easy to live with headset. The 4A I have had since about 1971 and the 4AA since about 1980. I have not heard any that sound that much better or are as easy to have on for extended periods. The 4A is now used with a boom mine for amateur radio and the 4AA for music.
  • Pros: Good isolation, great freq. response, nice ear cushions
  • Cons: strain relief could do better on the long haul

Koss needs a mic supplier.

  • Summary: I'm just about at the 1 year mark of owning these. They're about average as far as comfort, can't go more than a couple hours with them on at a time. They required lots of torqueing of the metal bands to make them crush my head less. The sound quality is the best of anything I've used.

Some Good-Some Bad

  • Summary: I use these headphones regularly on my HF transceiver. Good-Sound quality; they sound great and dampen the ambient background noise. Bad-Comfort; they are heavy and the piece that goes over my head will not extend far enough. When they are fully extended, there is too much pressure on the top of my head. To be comfortable, I must wear a hat to provide a cushion.

Good Phones!

  • Summary: I used the PRO4AA phones a lot in the 70's for stereo listening....the best that there was until Sennheiser came along (my opinion of course, and the Senn's were aimed at the "open air" crowd, not the "isolate the listener" crowd). The Koss phones allowed me to enjoy the full effect of the great electronic music groups without the expense of really expensive speakers. The only bad thing was the mass of the magnet structure...
