Quotes from the Reviews - What People Say about:

Cable

Cable:
"The image and stereo field is cramped into the middle of your head, the bass feels undercut and lacking all the time (which is even weirder considering how much of a seal they create against your ears), the things are relatively freaking heavy and uncomfortable, the cord is too short, and the sound is weak and simply not realistic in representation."
_
"I had a pair of AIWA from ten years or so ago that where $60 on sale then, probably over a hundred new today and the children ruined the cord using it for the computer."
_
"They insulate against outside noises very well - and I love how the generous jack cord manages itself!"
_
"One nice thing I can say about these is that the cord is very long, it stretches across my entire room which is great for when I want to be quiet at night."
_
"I wanted pretty design and a coiled cord, so I took a risk with Koss."
_
"The gold plating is nice but a detachable cord would have been a great add on."
_
"It makes owning a set of cord headphones quite nice."

Fit

Fit:
"Nice fitting headphones, poor sound very tinny Very weak bass and they have a buzzing sound."
_
"They were also a great fit, though the adjustable head strap is hard to work without taking it off of your head."
_
"And god forbid if my head was any bigger I wouldn't be able to fit them."
_
"Part of the good sound is a good fit (pressure) on your ear."
_
"Nice fitting headphones, poor sound very tinny Very weak bass and they have a buzzing sound."

"They never seem to fit perfectly to my head which is an average size."
_
"The phones are mounted in a curved-metal spring clip that fits into holes on the earphone cup and can easily be removed and replaced."

Heavy

Heavy:
"Negative::Bulky, heavy and ear sweat that's about it."
_
"Standard complaints apply: They're incredibly heavy and they'll make your ears sweat."
_
"The image and stereo field is cramped into the middle of your head, the bass feels undercut and lacking all the time (which is even weirder considering how much of a seal they create against your ears), the things are relatively freaking heavy and uncomfortable, the cord is too short, and the sound is weak and simply not realistic in representation."
_
"The only problem is that your neck starts to hurt after wearing them for a while because they are heavy."
_
"The main complaint that I read of them being heavy has yet to bother me."
_
"My only complaint is that they are a bit heavy and squeeze your ears (especially if you have glasses)."
_
"GREAT sound quality, but just too heavy."
_
"They are heavy and well put together."
_
"I found them heavy out of the box but very comfortable when wearing them."
_
"After a couple of hours they get to be pretty heavy and I have to take a break to let my head rest."
_
"The KOSS earphones inspire confidence, as they are heavy, fit snuggly and comfortably, and do not spontaneously break."

Level

Level:
"Problem is that at the level necessary for them to sound good I have to limit my exposure as the ensuing fatigue and ringing in my ears makes a listening session less than enjoyable."
_
"Cons:- My biggest complaint with these headphones would be that the bass sound level is somewhat soft."
_
"all my life i've enjoyed listenin to music to the maximum level i could possibly reach before unbearable distortion...and these pair of headphones deliver."
_
"As well, they are not the most efficient headphones so hard to drive to very high sound levels without an amplifier."
_
"It's made completely out of plastic and to me it's ridiculous that a supposedly Professional level headphone should be so brittle at such a crucial location."
_
"One thing to consider though if you're going with quality headphones is a quality soundcard and good software that you can manipulate the soundlevels with, straight windows audio controls won't cut it, I use SoundMax to adjust the levels and it works really well."
_
"For instance, I can listen at a lower level with my Audio Technica ATH-AD700's and still get all the musical information and enjoyment that takes a higher sound pressure level for the Koss' to deliver."
_
"Nothing I did ever raised the Pro4AAT's sound quality to even the level of a cheap set of Sennheiser PX-30's or 40's, much less something on the level of Grado SR-80's, which consistently outperform the Pro4AAT's in bass, midrange, and treble."
_
"Problem is that at the level necessary for them to sound good I have to limit my exposure as the ensuing fatigue and ringing in my ears makes a listening session less than enjoyable."
_
"- The mid-range and treble sound levels are really nice on these."

Listening

Listening:
"I had my pair of Koss headphones for several months and tried listening to them several times but they sounded so terrible I couldn't stand it; the sound being dark and dead."
_
"-----------------------------------------------OK, here's an edit update from June of 2013:I still have these same phones and have been using them off and on since I purchased them and have come to the conclusion that maybe their sound has morphed into something a bit less horrible since I first started listening to them...BUT, as it turns out, it takes listening to them at levels louder than I want to listen."
_
"Hmmm... maybe that last item should be a pro given the damage many of us have done listening to music at overly high volumes."
_
"I put them on before listening to anything and found it hard to hear anything (always a good sign)."
_
"He took them out of the box and was complaining about how they just weren't the same, then he put them on, and started listening to music, he has had a smile on his face ear to ear ever since, and told me how much lighter and more comfortable they were, he also mentioned that he hated to admit it but they also sounded beter."
_
"Happy Listening..."
_
"I can honestly say listening to the end product is fantastic."
_
"Also, the headband piece has an adjustable tongue slot mechanism at each side, enabling comfortable listening by children and adults."
_
"They just arrived and am writing this while im listening to Deep Purple-Machine Head on Vinyl through these great headphones."
_
"Surprisingly given the tight seal and all that I don't find them uncomfortable for extended listening."

Music

Music:
"I am neither as I like them with some music and hate with some other."
_
"all my life i've enjoyed listenin to music to the maximum level i could possibly reach before unbearable distortion...and these pair of headphones deliver."
_
"As far as the sound... highs are good, mid range... bland, bass... think about listening to music coming from the other side of a thin wall, terrible...they sound muddy, lack clarity, lack dynamic range, very disappointing."
_
"Hmmm... maybe that last item should be a pro given the damage many of us have done listening to music at overly high volumes."
_
"But unfortunately here is the bad, I expected them to be a lot louder for how large they are, I was disappointed when I put them on for the first time and cranked up my music full blast and I could still hear the TV in the background."
_
"He took them out of the box and was complaining about how they just weren't the same, then he put them on, and started listening to music, he has had a smile on his face ear to ear ever since, and told me how much lighter and more comfortable they were, he also mentioned that he hated to admit it but they also sounded beter."
_
"Pro:The sound is great on most music."
_
"I hear many of the small treble effects, like chiming on guitar strings, to be just flat gone, and forget about hearing any texture in the music...these things are great homogenizers of what ever is fed them...kind of like MP3's at even the highest bit rates corrupt the sound in comparison to the original CD, DVD-A, or SACD sound quality...I am older so clean and clear treble is a necessity for me, any distortion in this region reduces listening enjoyment and leads to fatigue...but, the PRO4AAT's don't even seem to reach that high and what treble that is present is greatly lacking in clarity and extension...which is a problem that I do not have with the aforementioned PX-30's or the JR-170's, much less the SR-80i's, SR-125i's, or SR-325i's from Grado that I have listened to extensively."
_
"I pretty much only have time to listen well recorded music, mostly classic rock, jazz and classical, never any MP3's, and have pretty decent analog and digital gear...such as a Sony SACD player, Teac reel to reel tape decks, an old, but very good sounding CD digital setup with a Philips CD-80, and a Home Theater PC feeding it's digital output to an Audio Alchemy DTI 2.0 and that feeding a DDE 1.2 HDCD DAC...my Linn Sondek has the Ittok LVII arm, cartridges range from Benz woodies to Ortofons, to, well, just too many to mention here...all these are fed through an Audible Illusions Modulus 3A preamp...the ASL headphone amp is fed from the tape loop output of the AI...current headphone amplifier is a tweaked Antique Sound Labs MG-Head OTL MkIII DT...main speakers are Martin Logan Aerius-i electrostats...cabling is Wireworld, Cardas, etc...power cables are Shunyata...I vary between tube and solid state amps powering the ML's...To give a comparison to something else in the Koss line, I have a pair of the JR-170 wireless headphones."
_
"If you love to listen to your music with a ton of bass, then these aren't the headphones for you."
_
"all my life i've enjoyed listenin to music to the maximum level i could possibly reach before unbearable distortion...and these pair of headphones deliver."

Noise

Noise:
"After disappointing durability with Sony noise canceling headphones, which ate batteries and were quite flimsy, I bought the AAT's having owned a pair of Pro 4 AA phones in the 70's."
_
"although I will still use my dead headphones because they hide outside noises they wont be put to used as headphones as the right ear died on me."
_
"Also I don't like the material of the ear pads, they make this annoying squeaky noise whenever you move."
_
"Didn't block out exterior noise very well, so I returned them, then found the best pair of headphones I've ever heard and for half the price... California Silverado headphones from CaliforniaHeadphones."
_
"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."
_
"They insulate against outside noises very well - and I love how the generous jack cord manages itself!"
_
"They are not noise cancelling but are effective at muting ambient noise."

Price

Price:
"The full ear cups are sealed in a high-quality vinyl which remains soft and pliable (I hate those cheap fabric-covered foam ear cups that either break down in a short while or the fabric basically DISSOLVES)."
_
"Once again, the cheap, cheap, cheap Sennheisers I mentioned before actually outperform the Koss here...but, the cheap Senns aren't really that good of 'phones in the grand scheme of things, but work out well as gifts to younger folks wanting something better than their ubiquitous earbuds...I've had these Koss phones for a couple of years now and did have them spend many hours (well over 100) alternating between using burn-in disks and playing music, yet nothing I have done has been able to make these phones sing....But, there is one use for them I have found that is just great...and that is when I use them with my Ham Radio gear...it doesn't matter whether it's TenTec, Yaesu, Collins, or Drake, the Koss phones work well for Ham Radio usage...in this instance the lack of high frequency clarity and extension actually comes as a benefit with the kind of noises we have on the HF bands."
_
"Keeping your hands on the cans helps stabilize this...- Crappy, cheap ear pads."
_
"Why would I waste my money to compensate for the failings of these cans?"
_
"Get them here for the amazing price of $49."
_
"I think I paid around $60-70 for these, and based on the lack of comfort I'd say they should go for about half that price."
_
"That said, these are excellent phones for the money or anywhere near it and I do not regret the purchase."
_
"Overall: great set of headphones for the price, look really slick, sound is great if tweaked often for different types of audio you'll be listening to, be prepared to take breakssometimes from wearing them."
_
"Sound: The sound is great, you won't be dissapointed unless you're some kind've audio nutcase that is looking for perfection, IMO if you're that type of personyou shouldn't be expecting that from something around this price range, but these headphones are definitely worth the money and produce great sound quality."

Quality

Quality:
"The Koss Pro4AAT headphones are quality headphones, but sounds weak when driven through a regular headphone jack from your receiver or tv."
_
"I don't know if I've gotten more discriminating over the years, if Koss has degraded in quality, or maybe I've gotten a lemon."
_
"I'm just now hearing that some of my files aren't very good quality, because I'm hearing hisses and stuff I never heard before."
_
"I would not recommend this hi-end quality product to anyone, even for my enemy!"
_
"Sound quality is not that good that I was expecting."
_
"GREAT sound quality, but just too heavy."
_
"I do enjoy the sound quality--if you get the plastic-y ear pads to seal against your head with moisture on your skin (disgusting, right? )"
_
"Build quality is good, sound quality is good."
_
"KOSS PRO4AAT Stereophones have very good sound quality, but tend to lack any form of bass and comfort."

Response

Response:
"Unfortunately, the bass response is just not that good."
_
"The Pro4AATs have mediocre bass response at best."
_
"Sound-wise, the bass response is excessive and muddies midrange vocals, while extreme highs are somewhat recessed."
_
"These seemed somewhat comparable in bass response to Pro4AA, are lighter and more comfortable but way too bright in the upper frequency range."
_
"These headphones (what, with all their titanium coating and that nonsense) really fall flat on their face, and not in a frequency response 'good' kind of way."
_
"The Pro4AATs have mediocre bass response at best."
_
"The bass response was good, they were THE most comfortable headphones I've ever worn, and they've lasted a good many years."
_
"Those have fair quality, especially at 15$.Response is great, as you would expect."

Sound

Sound:
"It is a shame these great sounding headphones are prone to this failure."
_
"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."
_
"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."
_
"Nice fitting headphones, poor sound very tinny Very weak bass and they have a buzzing sound."
_
"It sounds beautifully."
_
"GREAT sound quality, but just too heavy."
_
"Pro:The sound is great on most music."
_
"It is a shame these great sounding headphones are prone to this failure."
_
"Part of the good sound is a good fit (pressure) on your ear."

Weight

Weight:
"And out of the box, they preformed just as good as the ones before (great).Some people complain about the weight."
_
"Thats the only drawback the weight, but i doesnt matter to me (also I dont think the lifetime warranty covers AUS but you never know your luck) At least they are not cheap chinese .....For overseas buyers i'm in Victoria Australia and took 11 days with Expedited International Shipping."
_
"Well, the discomfort from the sweating is actually greater than the one from the weight."
_
"Do the research and buy something else - don't be fooled by the sleek looks and solid weight in your hand - or the word Pro."
_
"For all you weenies that complain about the weight, get a life."
_
"And out of the box, they preformed just as good as the ones before (great).Some people complain about the weight."
_
"Six months laster I am enjoying the sound just as much, and am living with the weight ok."
_
"Physical: These headphones are really slick professional looking, although the material the clips and headband are made of look like a somewhat toughplastic, I can assume by looking at it that it could easily break if it were dropped by accident and the weight of the whole thing might make that alot more possible, soit's a good idea to have something setup to hold them in place on the desk wherever you use them, or put them up after every use somewhere safe."
_
"I love these headphones; they sound great, don't weight too much, and sit on my head comfortably."
_
"I love the weight to them, the sturdy looking feeling construction, and especially the lifetime warranty."
