Quotes from the Reviews - What People Say about:

Adapter

Adapter:
"I tried using them in this manner via an adapter, and was very disappointed."
_
"My existing set is wonderful and the only problem was having to use a 3.5mm to 1 4 stereo plug adapter.....this was causing intermittent sound loss and some static."
_
"I would give five stars if it came packaged with a quality adapter for use with a small headphone jack, generic adapters don't work great and will cause static and sound loss when barely touched."
_
"Hook the RCA jacks to the phono inputs in the back and WHAM they work great and they plug right in no adapter required."
_
"Perfect for my hi fi system, down to my iphone -when using the 6 to 3 mm adapter."
_
"My existing set is wonderful and the only problem was having to use a 3.5mm to 1 4 stereo plug adapter.....this was causing intermittent sound loss and some static."
_
"It can be easily remedied by buying a $5 1 4 to 3.5mm adapter, but looks very odd (and can cause bending issues) coming out of an MP3 player or computer."
_
"You'll probably have to buy an adapter (very cheap, < USD 5), but be careful to choose a good quality one, as a poor adapter can spoil the awesome sound quality2) size and weight: make no mistake, these are BIG headphones."

Audio

Audio:
"I tinker with my computer and thought that it was possible my audio card was broken when suddenly all audio only came through the left ear phone- so I plugged it into my amp and played the theremin and confirmed my headphones are shot."
_
"I'm no audiophile, so I can't speak much to audio quality; I can hear junk, but anything above a reasonable midrange sounds equally good to me."
_
"The imaging and dynamics are both excellent, and although the imaging is not quite as good as a pair of Audio Technica ATH-M50s I own, these provide for a better overall listening experience over time."
_
"Get these if you're serious about a great audio experience."
_
"The Audio Technica are way more efficient than the original Koss Pro 4aa, and quite a bit lighter and more comfortable."
_
"It's just unfortunate that KOSS offers many great & comfortable headphones, but can't seem to connect highest possible audio quality with highest possible physical comfort."
_
"YES, the audio quality is much greater, but at what cost?"
_
"Same high-quality audio as I remember from the set I had in the Army."

Comfortable

Comfortable:
"Pro's: not expensive, very durable, comfortable, look classic, and sound great (The bass is there unlike the Koss QZ-99 model)."
_
"They sound great and although they're heavy, I find them to be pretty comfortable for an hour or more at a time."
_
"It's just unfortunate that KOSS offers many great & comfortable headphones, but can't seem to connect highest possible audio quality with highest possible physical comfort."
_
"Well, apparently that cost is ear & head comfort - less breathable, much tighter, and heavier."
_
"Whether lying down or standing up, the Pro-4AA's are extremely heavy and less adequate in comparison when it comes to comfort."
_
"The sound is as I remember from the ones I'd bought in 1979 or so, and while the ear cushions don't feel exactly the same original liquid-filled ones back then, but they are just as comfortable, and seal very well."

Design

Design:
"I mainly wanted the pro4aa standard set because I really liked the old school design of them, some peoplewill have negative comments to say about the design, but it's basically a personal preference, I really like the retro design, makesme feel like I'm in an old studio wearing them."
_
"Retro in design, but probably the best pair of headphones I have owned and used."
_
"The closed cup design reduces noise sufficiently that I can listen to and enjoy music with persons walking nearby and with the television on in the next room."
_
"The main reason I purchased these headphones was due to their durable design and lifetime warranty, but also heard about their noteworthy history and lifespan."
_
"Koss, IMO, have used their huge experience and no doubt unique access to specialist in-house materials, employed successfully for well over 30 years in the same design, to keep costs down, and carefully updated key components, whilst very cleverly voicing the PRO-4 AAs sympathetically to the originals, but at the same time also adding a more modern and incisive sound."

Fit

Fit:
"Love the sound (very natural, I think), pretty good isolation, they seem to be pretty durable, but they fit really tight, they're very heavy and cause pain to the ears and neck after a while."
_
"The frame is steel and can easily be bent to fit the user's head."
_
"The headphones fit on my head, and the cups fit over my ears perfectly, with the right amount of tension pressing against my ears."
_
"These have fit the bill perfectly."

_
"Some may find them heavy and uncomfortable, but once you put them on, the sound is worth it."
_
"They are a bit heavy and can get a little uncomfortable with long term use."
_
"These phones are heavy, a bit awkward, and look a bit dated unless you want to look like your about to construct aircraft carrier traffic."
_
"They look dumb, they're big and heavy, and they need to be broken in, but they sound great, and they'll last long enough to make your grandkids look like nerds."
_
"heavy, hard, and uncomfortable, For someone who spends hours a day in a set of cans, these were about the furthest thing from ideal as possible."
_
"They sound great and although they're heavy, I find them to be pretty comfortable for an hour or more at a time."

Listening

Listening:
"One use the Pro-4AA's excelled at - and still do - is listening to short wave broadcasts, as well as DXing, the process of listening to distant and weak stations."
_
"I just don't use them as much as I'd like, because unless I'm in my office, laying on my couch, listening to my turntable, they are too uncomfortable."
_
"Everybody says this in reviews, and I'm going to as well: they're heavier than you think they are, and they can get uncomfortable to support for extended listening."
_
"I would not recommend these for general music listening as they lack lower bass response but they are built down right durable for professional recording purposes unless you are a bassist or percussionist."
_
"And if your just planning on kicking back in the recliner and listening to some tunes to relax, then you cant go wrong."
_
"The sound comes through so deep, rich, and clear you almost feel like you were listening to music with cotton stuffed in your ears before."
_
"One use the Pro-4AA's excelled at - and still do - is listening to short wave broadcasts, as well as DXing, the process of listening to distant and weak stations."
_
"I like a decent amount of bass to give whatever I'm listening to some depth body."
_
"Excellent sound isolation as well for listening in a noisy environment or for keeping others from being bothered by what you are listening to."
_

Music

Music:
"No matter how good those phones are, when the music is that compressed it loses dynamic range."
_
"I went through countless pairs of earbuds before finally deciding they were uncomfortable and made all my music sound like it was playing through a tin can."
_
"I would not recommend these for general music listening as they lack lower bass response but they are built down right durable for professional recording purposes unless you are a bassist or percussionist."
_
"In other cases, you may discover that the music doesn't sound as great with the headphones, and it could leave you a bit disappointed."
_
"The only thing I can complain about is the fact that I am into metal music."
_
"If you just want 'jogging exercise music', then these will not work well."
_
"The sound comes through so deep, rich, and clear you almost feel like you were listening to music with cotton stuffed in your ears before."
_
"U can hear every detail of the music.. Must have a good amplifier to move this headphones."
_
"Takes me back to the days, when music was enjoyed and not just in the background."
_
"I listen to all types of music and it all sound perfect."
_
"The closed cup design reduces noise sufficiently that I can listen to and enjoy music with persons walking nearby and with the television on in the next room."

Noise

Noise:
"Sound: Sound quality is great, but not as good as the pro4aa in my opinion, but if you're looking for outside noise reduction, they do a really good job at that, and keeping sound in."
_
"Their sound-isolation feature can be helpful in various noisy environments as well..."
_
"And noise isolation is great."
_
"Yep, just like the old days, snug and cozy, and block out the ambient noises very well due to the sturdy construction."
_
"Crucially, they are also as effective at keeping noise out the other way, so that only the user is aware of any music being played, making these headphones ideal for use late at night where the slightest noise may disturb others sleeping."
_
"The PRO-4 AAs also shut out external noise extremely effectively (probably the most effectively with any headphones I've used to date), which certainly aids detail retrieval, as one's ears are immersed in total inky-black silence, from which music then emerges rather spookily."

Price

Price:
"The only downside of these are that they are Affordable, thus you can't brag about how much money you spent on your headphones, I mean, if you have a $700 pair of headphones on your head, you must be cool ... and a great musician to boot."
_
"It's not easy for me to recommend it at full price either."
_
"Despite the differences between the originals, I still recommend these headphones for anyone who wants a great sounding pair of headphones at a reasonable price that will challenge plenty of more expensive headphones on the market."
_
"Unfortunately, these great features come at a hefty price: the weight."
_
"-Really amazing price considering the sound and build quality and power impedance."
_
"A good pick for the price that you'll get a high end headphones at a good price ."
_
"They have excellent sound for the price."
_
",these will beat any Grado's or AKG's that are twice the cost,I'm sticking with this model for the rest of my life,Olivia Newton John's voice never sounded better as the vocals and midrange on these phone are too good to be true for the price."

Quality

Quality:
"These were a little uncomfortable, but I was willing to endure that for the quality of the sound over other headphones."
_
"I'm no audiophile, so I can't speak much to audio quality; I can hear junk, but anything above a reasonable midrange sounds equally good to me."
_
"Sound: Sound quality is great, but not as good as the pro4aa in my opinion, but if you're looking for outside noise reduction, they do a really good job at that, and keeping sound in."
_
"I may as well wear my earbuds as the sound quality certainly didnt make up for the construction quality and uncomfortable wear."
_
"It doesn't matter how durable and solid the construction is if you use a poor quality cable."
_
"Great sound quality, you wont be disappointed here!"
_
"( + ) superior isolation excellent sound quality."
_
"Sound quality is great!"
_
"Love the sound quality its simply amazing good stuff! "

Range

Range:
"These headphones deliver some of the best sound in *closed back* headphones in the under $300 range."
_
"Excellent full range, best there is."
_
"These have to be the best value in this price range."
_
"Good clarity (could be better), good dynamic range, good imaging, good basses, good midrange, good highs."
_
"Otherwise they perform very well as a vocal monitor for recording and some instruments that encompass the upper frequency range will also be heard in great detail."

Response

Response:
"The soundstage (separation) isn't quite as well defined in my opinion as the Bose, but the flat response and excellent overall sound quality give them at least as high marks."
_
"The Koss Pro 4aa have an excellent sound with very natural timbre, flat response and frankly little coloration perhaps because of their weight and large driver design."
_
"Amazing frequency response."
_
"The base sound is quite good, and I cannot fault the response at the higher frequencies."
_
"The superior response and isolation make Koss' 'old standard' the best on the market."
_
"They have great bass response."

Size

Size:
"I also read how heavy they were but after strapping these babies on and started to listen, I completey forgot about that small problem."
_
"Size matters: they are heavy, and bulky so they're not easily concealed; and since iPOD or MP3 players use the mini plugs, these require additional hardware."
_
"It's pretty small, like your right there in front of the performer."
_
"However, I'd like a longer cord (it IS quite long and curly - like old telephone cords -, but for home theater usage it needed to be longer) but that's not its major problems:1) 1 4 inch (6,3mm) connector: these are full size connectors, meaning it won't fit into 99% of household appliances, not to mention personal MP3 players, video games, consumer gears in general."
_
"You'll probably have to buy an adapter (very cheap, < USD 5), but be careful to choose a good quality one, as a poor adapter can spoil the awesome sound quality2) size and weight: make no mistake, these are BIG headphones."
_
"But if you really want to get lost in your music, try an open design--you can get lost in the sound the Pro-4AAs provide, but you'll be running around a pretty small block."
_
"Anyway, they are well worth the small investment!"

Sound

Sound:
"They sound anemic and thin when not driven well, and also harsher."
_
"Some may find them heavy and uncomfortable, but once you put them on, the sound is worth it."
_
"I have a pair of $40 earbuds that sound nearly as good, with none of the discomfort."
_
"They sound good, but all the cords were frustrating."
_
"These were a little uncomfortable, but I was willing to endure that for the quality of the sound over other headphones."
_
"They certainly are great sounding - to me - just not comfortable enough."
_
"( + ) superior isolation excellent sound quality."
_
"These are good headphones,but do not produce the sound I thought I would hear."
_
"The sound comes through so deep, rich, and clear you almost feel like you were listening to music with cotton stuffed in your ears before."
_
"Sound quality is great!"
_
"They sound great and although they're heavy, I find them to be pretty comfortable for an hour or more at a time."

Stereo

Stereo:
"Problem solved by buying Sennheiser HZR-62 Stereo Volume Control."
_
"My existing set is wonderful and the only problem was having to use a 3.5mm to 1 4 stereo plug adapter.....this was causing intermittent sound loss and some static."
_
"Without a headphone amp, the soundstage (think stereo widening, or feeling encompassed in sound) is terrible."
_
"I have used these in professional sound reinforcement systems as mixer monitors and now have a pair for my home stereo system as well."
_
"A really great buy for someone who likes good quality sound and is a stereo buff."
_
"Remember, these were designed in the 1970s, when speakers, stereos, and records were engineered to actually sound _good_, not just more kickin' and or loud (loudness curve).These are truly high-quality, and I'd buy them again in a second."
_
"My existing set is wonderful and the only problem was having to use a 3.5mm to 1 4 stereo plug adapter.....this was causing intermittent sound loss and some static."
_
"I recommend the Cables To Go - 40636 - 3.5mm Stereo Male to 1 4 Inch (6.3mm) Stereo Female Adapter over the one that appears on the page for these stereophones, it's more sturdy than the ARISTA one that appeared when I bought the headphones."

Warranty

Warranty:
"The 8ft cord is longer then I remember on my old ones (longer than I prefer), and maybe not as heavy, (but more flexible) and the 1 4 stereo plug molded onto the wire, and is not solid brass, and removable as was on my old Pro-4AA, it is perfectly adequate, and with a Lifetime Warranty, who could possibly complain."
_
"The right channel did not work and ear pads were deteriorating, so sent back and paid $9 to repair under lifetime warranty."
_
"Hopefully I don't break them (but then again it comes with limited lifetime warranty, so whatever damage I do might just be covered).If anybody's worried about packing, shipping, etc, mine arrived fine."
_
"With a lifetime warranty, how can you go wrong? "
_
"-Koss's excellent lifetime warranty!"
_
"The 8ft cord is longer then I remember on my old ones (longer than I prefer), and maybe not as heavy, (but more flexible) and the 1 4 stereo plug molded onto the wire, and is not solid brass, and removable as was on my old Pro-4AA, it is perfectly adequate, and with a Lifetime Warranty, who could possibly complain."
_
"Thumbs up to Koss for honoring their warranty after all these years and having a terrific product that is still tops today."
_
"I am delighted to have these phones back in commission and am thankful that Koss Stereophones makes good on their warranty even after forty years!"
_
"They are built to last and wow a life time warranty you just can't go wrong with this deal."

Weight

Weight:
"Not very comfortable as the weight of the headband pushes down on select points on your head."
_
"Many of these reviews seem to complain about the weight of these headphones."
_
"Now to the negative: I read the reviews, but I thought all those that complained about the weight and pressure were just wimps."
_
"=) They sit well on the head, so there are no pressure points or localized discomfort, but the weight is still there."
_
"I feel therefore that their apparent 'excessive weight' is somewhat overplayed (although they do tend to 'clamp' your head in an almost vice-like grip), as is the 'sweat factor'."
_
"Another complaint from others is the weight."
_
"After saying that the 4AA sounds great, I was hoping something was done about the weight when purchased, I did hear koss made a similar phone."
_
"It is considered heavy in weight (insulated) which is one of the reasons for its superior sound isolation."
_
"You'll probably have to buy an adapter (very cheap, < USD 5), but be careful to choose a good quality one, as a poor adapter can spoil the awesome sound quality2) size and weight: make no mistake, these are BIG headphones."
_
"Don't get me wrong they are heavy (the weight does not bother me) by today's standard when comparing to newer style headsets, but then again this one is not made of cheap plastic and foam."
_
"While the sound quality is very good, the tight fit and heavy weight of the headphones is just not worth the listen."
