Customer review

I had a pair of Pro-4AAs back in the 70s. At the time, I thought they were the greatest sounding headphones ever made. Short of kilobuck electrostatics, perhaps they were. I wore those old Koss cans for most of the decade, which probably explains the groove across the top of my head, because they are heavy.

After a few intervening decades of lightweight headphones, ear buds, and other over-the-ear headphones, all of which sounded like crap, broke quickly, bled sound all over the office, and mostly annoyed more than they overjoyed, I finally decided to return to something I was familiar with.

I got the Pro-4AAT rather than the Pro-4AA classics just because the -T has a 3.5mm plug on the end of the cord, and I’ve had such bad luck with 1/4″ to 3.5mm adaptoplugs in the past.

They sound pretty much as I remember. In fact, they sound good enough that I’ve come to realize just how crappy most MP3s sound, and how poor the DAC on my tablet is. Which means going back to FLACs and plugging in a DragonFly DAC. Which sounds great, by the way.

One other advantage that doesn’t get mentioned much is: Who the heck needs sound deadening headphones when you have these? When I put these on in the office, they isolate me from ambient noise so well, that I’ve had people walk into my cube, stand behind me and talk, and I’ve never heard them. Even during the quiet parts.

Standard complaints apply: They’re incredibly heavy and they’ll make your ears sweat. Not recommended for people who live with other people who want to talk. But I’m used to all of that.

Customer questions & answers

Q: Is the bass good for listeners of classic rock, but dont do rap or games?

A: THESE ARE TERRIBLE FOR BASS OR ANY KIND OF MUSIC. I’D USE THEM FOR SPEECH ONLY. There sound is particularly tinny and mid-range. NOT GOOD FOR MUSIC. Hope you find this helpful. I have a pair here I can’t give away.

Q: What size is the input jack?

A: 3.5 mm stereo jack

Q: Koss 4AAT’s or 4AA what differences that one may consider?

A: T stands for Titanium. So the “T” have Titanium speaker cones and “presumably” sound better and produce less distortions.
To me they sound tinny and dull. I really do not like these except for music like BS&T with lots of brass. They also stick to your cheeks and ears. My favorite and cheaper ones, also more comfortable are either AKG K77 and/or Sennheiser 4..-5.. – (don’t remember which – with velvet earpads) These are more “professional” in sound – more highs and just enought lows for me.

Q: Is the cord detachable so it can be replaced with a shorter one(that is not a coiled one so it’s lighter.

A: The cord is not detachable. You could use an extender cord that is not coiled you will still have the coiled factory one attached. 🙂
