Bottom Line:   
Sonically these headphones are fine at the price but the sheer physical weight of them is just ludicrous in this day and age, ultra fatiguing and the earpieces are insufficiently deep to avoid pressing painfully on my ears but that will possibly not be the case for others. Going to splash out and get myself some nice LIGHTWEIGHT HD 600 Sennheisers....quality costs. So my advice is to check the comparative weight of your headphones before buying.

No where near the phones the 4AAA are. I have both and thinking the AA would be lighter I bought them as was sorry within a month. Both end caps on the band became loose so I super clued then back in to position. They have nowhere near the bass and some male voices sound like their in a tin can. Wife uses them from time to time, she has a tin ear.

Bottom Line:   
i bought these headphones a weak ago, both because i've heard that they sounded really good, and because i found them at half the price on the internet. the package contains the headphones + koss's lifetime warranty, a nice bag to store them in, and that's it. one thing i missed was a manual for such expensive headphones, that would describe how to treat the headphones and so on.. when i first tried them on, i got really disappointed about the sound, because they sounded like garbage. metallic, and with no clear treble or bass, the sound was familiar with cheap headphones. then i thought that i might had to play them in, and put them on the stereo constantly...after a few days they sounded just amazing! deep bass and correct sound with crystal clear treble and midrage, i would really recommend this product. the only thing that annoys me is the headband, and ofcourse the weight....

Bottom Line:   
Sometimes the sequal just isn't as good as the original... that describes these classics from Koss. I had the originals, which offered a nice neutral sound with deep bass and decent treble. Sure they were heavy - and very, VERY fragile, but they were truly decent back in the 1970s.

Now if Koss simply re-issued the same headphone out of old time sake, I'd like to have a pair. Make the headband more durable (for example) and keep that same sound... I'd like to have a pair out of old time sake. BUT these don't sound like the originals! The bass is bloated, the treble is muted and "slow" (lacking any hint of "airiness") - a dissapointing sequel.

If you want to get a feel for how headphones were back in the 1970s - for the price (which is very heavily discounted) - pop for a pair. At least the bass is there. Otherwise, some things are best left in the past.

Bottom Line:   
This review is for the "NEW" version of the Pro-4AA's that has been re-designed and is different from the "OLDER" version. First of all DO NOT waste your money on this new version of the Pro-4AA especially if you had the older version. They are made like Garbage!! Cheap plastic and cheap materials is what makes up this new version. I removed one of the ear pads,and there were 2 staples holding down the mesh pads to a piece of cheap felt!! I couldn't beleive it!! The adjustable headband is made so poorly,it's a struggle just to adjust the size. And of course most importantly;The Sound. At 250-Ohms impedance they are difficult to drive,even with a Headphone Amp. I am a headphone enthusiast and use a well known high-end Headphone Amp; and they sound like total crap!! The old version was WAY better than these,all around. If you want to spend $100 get a pair of Sony MDR-7506,Sennheiser HD-280 or AKG K-240S which all will absolutely blow these away.
