Summary:
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.

Strengths:
Lighter

Weaknesses:
Can hear what people are saying around you. Lacks fullness and has poor bass.

Summary:
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....

Strengths:
very good and clear sound - solid construction

Weaknesses:
too heavy and tight to wear for a long period - a bit uncomfortable headband - no manual included

Summary:
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.

Strengths:
True deep bass from a headphone. Excellent acoustic isolation. Cheap street price.

Weaknesses:
Lackluster treble performance - lacks the midrange "richness" of their original couterpart. They are very heavy... but I've got to say that is part of the nostalgia - I guess.

Summary:
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.

Strengths:
NONE

Weaknesses:
Horrible Build Quality.Horrible Sound.Overpriced.

Price Paid:  $0.00

Summary:
This is a great headphone. The sound quality is excellent and very clear, it handles trebble and bass without any fuss, and has the largest freq. respone on a headphone under $100 I've seen. I've heard many good things about Koss headphones, and decided to get these after reading the positive reviews on this website. When I got them from J&R, I realized that I underestimated how heavy these headphones are. I've read all the warnings, but never imagined headphones could be so heavy - but they are! Imagine having a pair of speakers hanging from your head - you get speaker quality sound, but you also get speaker weight. These are pretty hard to drive - my Pioneer receiver did fine, but my computer's Sound Blaster Platinum had trouble pushing these heaphones to the same level. I finally returned them after a month of use, not because of poor sound (these headphones really rock when it comes to sound, even at very loud levels, I didn't hear distortion till 98db), but out of sheer discomfort - I couldn't listen to them for more than half an hour at a time, and my head and ears got very sweaty because of the cussions. I needed headphones that sounded good and that i could wear for prolonged periods of time. Koss Pro 4AA offered great sound at a great price, but I couldn't wear them while writing a paper or reading a book. Recommended for people who have strong necks and want to hear everything clearly and without distortion.

Strengths:
Excellent detailed sound - perfect trebble, almost perfect bass. Very good for critical listening - you'll hear stuff you've never heard before.

Weaknesses:
HEAVY! VERY HEAVY!
