If you are into an old school fully enclosed headphone it's difficult to beat this pair. This is a sturdy time tested design has been around since the 1970s. It produces a smooth and accurate sound while eliminating a great deal of outside noise distractions. These do not feel like a modern light headphone they are a bit heavier due to the solid construction and oldschool design. This aspect is a big part of their charm. The 250 ohm rating does require you to turn the output up quite a bit more than you would on other headphones. This aspect does not detract from the good sound quality it just means you need to use more energy to drive the headphone. Play back at low volume may seem a bit lacking, however at mid and high volume you receive a rich full sound. Sturdy construction with a good quality sound production and a lifetime warranty, it's hard to beat this pair of headphones.Read full review

These were my first 'real' headphones from 1974-1979. Even with moderately-priced Japanese electronics of the era, they sounded amazing in my late-teen years. I sold them in 1979 for AKG K240 Sextetts. I haven't heard them since then until I decided to hear my old reference in early 2016. I have every reason to believe the Pro4AA I bought from eBay are in good shape sonically and all-around, and built sometime in the '70s. They have the vice grip clamp on my head and ears and are very heavy by today's standards, which I expected. I didn't expect the sound was so, uh, colored, nor do I remember it being so much so. A huge upper-bass emphasis ~300Hz, still-strong bass below there, that render mids and treble way into the background. And this is using equipment that is far more open and capable than my '70s electronics. Eventually I plugged them into a good receiver with tone controls: it actually requires only minor adjustment to cut bass and boost treble to get a more-even tonal balance. Though that's imperfect vs proper equalization, it does show the high frequencies and vocals are actually fairly well-rendered even compared to modern $100 MSRP closed-back headphones. And it remains a remarkably well-built robust piece throughout, as their materials, condition, adjustability and even sound prove out. Compared to modern reference-level headphones there's no comparison sonically. But in 45 years you'd expect headphone technology to move forward substantially, especially with the relatively recent mainstream popularity of headphones. But for $25 they're well worth keeping as a not-awful-sounding piece of high-end history. Comparing them to brand-new current-production $100 Koss Pro4AA from the factory, er, well, that's a different review...Read full review

This will be a different review for I didn't buy the headphones for the purpose they are intended and that's listening to music while sitting. Before I go to sleep I do a pre-sleep session so that when I do hit the sack I won't lay there thinking. Doing a pre-sleep session prepares me to start snoozing the minute I lay down for serious and then I sleep for approximately 7-8 hours of solid sleep. However, the reason I bought these headphones is because I am a titanium person and I presently own 2 pairs of the rare, vintage ('90s) Sterling Te-400 (originally $139) which I swear are the best-sounding headphones I have ever heard since the 1960s and they are light on the head but not loose enough to fall off when I use them flat on my back. But the cables started shorting near the volume controls and I kept repairing them but the cables got shorter so I decided to replace them and the KOSS sounded like a good replacement and the higher ohmage (260 versus the Sterling's 60) made me think that the sound would be superior although it was only an assumption since I'm not electronically-savvy. High-end, expensive headphones usually feature an ohmage of between 260 and 300. When I received the KOSS the first thing that hit me was the weight due to superb craftsmanship and materials. Also, these headphones surround your ears while my Sterlings rest on the ear and I prefer that style. Unfortunately, the weight worked against me when I laid down and the headphones slipped off my head. Immediately I knew I wasn't keeping them. Then I played music and while the reproduction was excellent thanks to the titanium element instead of mylar or whatever. But, as a headphone forum member mentioned, they are a bit laid back while my Sterlings bring the sound to your ears, have deeper, natural-sounding bass (not bloated), and require less volume than the KOSS. To cut to the chase, these headphones are not for my listening purpose as explained above. Also, I think that my Sterlings produce true natural sound as if you were in the recording studio listening to the actual instruments. And their light weight make the headphones disappear. With the KOSS you always know you're wearing big, heavy headphones.Read full review
There is not a lot that needs to be said. How do you describe the best stereo headphone ever manufactured. I could write for a solid hour about the frequency response, sound quality, low distortion rating, etc, etc. But instead of boring you with technical jargon, all I will say is buy 'em, try 'em and you will be in stereo ecstasy! Whether you dig classical, rap, country, metal, classic rock, jazz, whatever you listen to, these are the greatest sounding headphones ever made! They have been the standard of MANY recording studio engineers for decades! Buy a pair and you will QUICKLY see why!

I needed a good set of isolation headphones to use when I'm practicing on my drum set to cds. Works great. Great sound and isolation. I have used Koss phones in the past, never disappointed in the quality or the sound!
