Got a new pair of cans today, the AKG K242 HDs, which are the consumer-oriented version of the popular K240s. Gonna be burning them in over the next few days before posting my opinions here.
 
From what I've heard so far, they sound a bit muffled, though that may go away after a few hours. Sibilance is present at slightly above-average volume levels, though everything else is exceptional for the price. Sound stage is beyond decent, though hardly exceptional (that's what I get for auditioning a pair of LCD-2s), and imaging is good. Just good.
 
Look forward to an update (not that these cans have been starving for attention lately)!
 
 
 
 
EDIT (I copy/pasted the review from a few posts down, to save readers the trouble of scrolling):
 
 
And here is the promised follow-up:

After a week of burning them in (my usual playlist + pink noise and freq. sweeps), I'm going to give my final impressions on these cans. For the record, the reason why I took so long to post this follow up was because the K242s I'm using now are a new pair sent in after my original ones suddenly broke (these cans have definite durability issues). That wouldn't have been such a huge issue, if it hadn't taken AKG over a month to replace them.

 
... Seeing as following that line of thought might lead to a biased review, I'm going to drop it now. 
 
Anyway, on to the actual review.
 
Test tracks:
1.) Achilles Last Stand (Led Zeppelin - Presence) @ 320 MP3(Rock)
2.) When the Levee Breaks (Led Zeppelin - Led Zeppelin IV) FLAC (Blues Rock)
3.) Sairin: Katatsubasa no Tenshi [Advent: One Winged Angel] (Final Fantasy VII: Advent Children OST, Disc 2) FLAC (Orchestral)
4.) Gods Bound by Rules (NieR Gestalt & NieR RepliCant Original Soundtrack, Disc 1) FLAC (Vocal)
5.) Welcome to The Jungle (Guns N' Roses - Appetite for Destruction) @ 320 MP3 (Heavy Metal)
6.) Green Dolphin Street (Miles Davis - Kind of Blue) FLAC (Jazz)
7.) The National Anthem (Radiohead - Kid A) @ 320 MP3 (... What genre is Radiohead?!)
8.) S/C/A/R/E/C/R/O/W/ (My Chemical Romance - Danger Days: The True Lives of The Fabulous Killjoys) @ 320 MP3 (Punk/Alternative Rock)
9.) Comfortably Numb (Pink Floyd - The Wall, Disc 2) FLAC (Progressive Rock)
10.) The Catalyst (Linkin Park - A Thousand Suns) @ 320 MP3 (Avant-Garde Rock)

About the reviewer:
I'm a college student who has only recently (recently being approximately three years ago) gotten into classical music, orchestral, classic rock, and the like. I like to think that my ears are in good condition (though I suffered from a perforated right eardrum when someone bumped into me while I was cleaning my ear out). Whether that last bit of info will prove a discredit towards my capability as a reviewer remains to be seen, though I've noticed sounds coming in through my right ear to be slightly muffled. 

 
I'm not a bass head, and I never play music at obscenely loud volumes. The K242s are by far the best cans I've ever owned, the only reference point I have being an Audeze LCD-2 I auditioned several months back. 
 
Anyway, I tried to include as many genres as I could while keeping the review to a manageable size. The fact that a lot of the review tracks are rock songs is probably due to the fact that I love rock and many of its subgenres. I also really enjoy instrumentals, orchestral works and choir music, which accounts for the inclusion of all the other tracks. I'm also a gamer, which is why I managed to include songs from NieR and Advent Children. Technically though, the latter track (One Winged Angel) is from the movie sequel to a game.
 
I listened to the MP3s through the portable setup (Source A), while the FLAC files were played through the home theatre system. 
 
 
Review Proper:
The K242s have a very versatile character, doing well with nearly every musical genre I threw at it. My only complaints with them were that the soundstaging and imaging could have been better for the orchestral works, while there was a persistently muffled quality to all the tracks. It's something you get used to after a while, though, so it's only really obvious if you try A/B'ing it with, say, a Grado or anything else with an open design. 
 
I'm going to give my thoughts on the K242's performance based on how well they did with the above-mentioned tracks. I'll only go out of my way to name a specific track if there's something significant about their performance with the said track.
 
Treble:
Cymbals didn't quite have the right amount of impact to them, but no one's lauding these cans for their treble performance anyway, so that's to be expected. Then again, I found Welcome to The Jungle, When The Levee Breaks, and S/C/A/R/E/C/R/O/W/ much less fatiguing to listen to, so depending on your preferences, the *slight* treble roll-off could actually be considered a good thing. 

 
While the K242s get a passing mark for rock and the like, their performance with orchestral music is sub-par. Listening to stringed instruments becomes a bit of a chore, which doesn't do One Winged Angel any favors. The bass violins still sound excellent, but that's another thing entirely. 
 
Soprano singers also lose a bit of their edge, as was the case with Gods Bound by Rules.
 
Mids:
As you may already know, these are the K242's strength, as with the case of most other AKGs. Vocals are just superb. Sure, they don't have quite as much resolution or detail as some other dynamic headphones *SennheisercoughHD600cough*, but at the price point, it's great value for the money.

 
The midgrange is... velvety. I realize that since this is a review on headphones, that particular adjective might seem a bit out of place, but that's the only word I can think of to describe it. While other midrange-centric or balanced cans seem to have their 300Hz-5kHz a bit disjointed from the rest of the spectrum, their is a seamless unity going from the bass to the treble, which makes these really good cans for monitoring. Well, that's only of you don't take the treble roll-off and mid-bass bump into account.
 
Listening to these cans, I'd heard details in singers' voices that I'd never heard before. An inhalation here, a smack of the lips there, a clearing of the throat, and you're that much closer to actually believing that you're in the same room as the band you're listening to. Most notable of the above tracks is the remastered For No One, which perfectly captures McCartney's forlorn voice, his inflection, tone, and cadence being well-fleshed out.
 
Bass:
The bass is a bit on the heavy side, which may put off some people. It's nowhere near Audio-Technica's Pro700 MK2, which is practically a pair of subwoofers attached to your head, but it stands out slightly. I wouldn't say that the lower frequencies were muddy (I'm too polite to use that particular word for my headphones), but I'd concede that they are slightly "soft" performers. The aforementioned mid-bass hump isn't quite so salient as to ruin your listening, but it's easily noticeable, so I would recommend a bit of EQ tweaking to remedy that. 
 
The bass on The National Anthem and The Catalyst was moderately detailed, in that you could practically heard each string of the bass guitar vibrate on the former track, and realize that there isn't much in the way of actual detail behind the bass of the latter track. For the record, on Snow in Summer (a track also from the NieR OST), the drums sound excellent; the recording and mastering was well-done, so while the drums come off as a bit distant-sounding, though they retain all their strength and force.
 
Soundstaging/Imaging:
I'd give the imaging a slightly above average mark. since at some points, when there are a large number of instruments playing simultaneously, things start to get a bit jumbled. Generally, they do well in this area, or at least well enough to earn them a commendation from someone who infrequently listens to opera and the like.

 
In my experience, however, soundstaging is more of an issue with the quality of the recording itself, as opposed to the performance of the headphones. For instance, listening to a rendition of Carl Orff's Carmina Burana (in a performance conducted by Charles Dutioit), majority of the vocals in O Fortuna seem to come from a mile away (a bit hyperbolical, but not by much), which made it impossible to listen to in an environment even mildly noisy.
 
Then again, I've yet to try the K701/K702, so I may as yet take back those words. 
 
 
Overall:
The K242s are a bit darker than might be appreciated by most audiophiles, and the treble is a bit weak, though this is offset by a superbly smooth midrange. Good for rock, techno, pop, and other similar genres, as well as vocal-heavy tracks; not-so-good for classical music and jazz. 
 
 
P.S.
They have some durability issues, though, from what I've gathered, it is an issue that only affect some units. 
 
P.P.S.
I apologize if the review doesn't really meet the readers' standards. As I type this post-postscript, I look at my clock and find that it's around 1:20 AM. I'll probably edit this in the near future. 
 
... Yes, I re-read this and noticed several typos, which I just fixed. I'm getting rid of the review below, which is pretty much a perfect copy of this one, save for the fact that  they still have the typos.
Cheers!

A very good pair of headphones you got there! But my main "problem" with them is that they have an urge for power. Even if they are rather low-impedance. I had my pair for 1,5 years now and i still think they are very good ( if you have a clean source and some power )

The sibilance should lessen with some burn in, but they're still going to sound a bit 'muffled' I'm afraid. That's their main flaw, but still, you get a very nice midrange for the price you pay for them....better than a lot of similarly price phones,imo.

True, the muffled quality was more or less the first thing I noticed about them. Coming from a stripped down pair of semi-opens (more open than not), they sound a bit soft. Sort of like I'm listening with a cloth sack over my head. 
 
Has anyone experimented with these cans? And by "experimented", I mean modifying them to lessen the muffled presentation. If I had the  guts to play around with these cans (they're currently the priciest pair I've ever owned, though that may change in a few years), then I'd probably try to remove the foamy covering on the inner side of the diaphragm.
 
Spent around 10 hours burning them in, and they sound noticeably better. Either that, or my ears got used to them. The retailer recommended around 300 hours of burn-in though, so it may take a while before I make any final decisions regarding these.
 
Detailing has improved, as has the imaging and, to a lesser extent, the sound stage. I don't have a decent source of my own, so I'll have to borrow a rig, maybe; Any recommendations for a portable amp that goes well with these cans? I'm leaning toward the Fiio E7 myself, since I need the DAC capabilities.

The e10 is supposed to be better, if you can afford it....something like the audinst even better than that....going by reviews I've I read. I didn't notice any significant improvement going from the weak 0404 amp to the mkV, but that's going by memory. They still have that big boominess in the mid/upper bass that makes them sound a bit murky/muddy on some material. But they can sound really good with acoustic stuff and classic rock that doesn't emphasize that area of the frequency range. If I had time I'd try some simple mods....maybe changing the foam covering the drivers for some thinner material....thin speaker cloth or something....even swapping pads.

Do you know the differences between the K242s, K240s, K240MKIIs?

I haven't yet tried the older K240s, but I managed to audition the MKIIs a few months back. 
 
From what I can remember, the original K240s have been discontinued, and have since been replaced by the K240 MKIIs. Though I can only base my statement on reviews and comments I've read online, both cans are reputed to sound somewhat similar, so read up on reviews if you want to get any decent info on them. Some sources here on Head-Fi state that the original K240s are much harder to drive, so you'll probably need a good amp if you're planning to get them. That's about as much as I know about the K240s.
 
Moving on to the comparison between the MKIIs and the 242 HDs.
 
The only overt differences are the color of the headphones, as well as the fact that the cable of the K240 MKIIs are detachable, while that of the K242 HD is fixed. This means that should anything happen to the cable on my 242s, replacing/repairing it is going to be a lot more of a pain than if I'd bought the MKIIs. Also, the MKIIs come with two cables in the box, one straight and one coiled. They're a bit pricier, but said to be worth the extra investment.
 
Comparing the sound of both cans is going to be a bit more difficult. I only managed to use my PDMP (without the benefit of an amplifier) when auditioning the MKIIs, so they might not have sounded their best. Add to that the ambient noise in the store where I tried them on and you'll see why I'm reluctant to say with any surety which between the two is the better in terms of sound reproduction. Sound stage was the same between the two, as was imaging. The MKIIs sounded marginally better than the K242 HDs, in that they had more detail and a better-balanced presentation. That could be due to the fact that they were well-burned in, while my 242s have barely seen a week of use. Either way, I'm still reserving judgement until a few more months pass, when I can be sure that my cans have reached their maximum potential.
 
Basically, the 240 MKIIs are intended for studio use, while the 242s are the consumer-oriented variant of the original 240s. Aside from color and the capability to easily switch cables should anything unfortunate happen, there isn't much of a difference between the two. Oh, and I recall just now that the MKIIs also come with a spare set of pleather ear pads, though the velour ones that are common to both headphones are said to be much better at sound isolation and comfort. 
 
P.S.
Head-Fi is a great place to learn how to research; helped me out in college more times than I'd care to remember. Erm, learning how to sift through info, that is 
wink.gif

Aside from my personal listening impressions (which, if I may say, don't really account for much), all the above info came from looking into forums about the K240s, K240MKIIs, and K242 HDs. I picked the 242 HDs because they came with the better ear pads, and had a nicer aesthetic. Also, I was on a tight budget; the extra cash for a detachable cable, while attractive to some (myself included), I just didn't feel the expense to be fully justified.
 
Good luck, and hope you have enough cash to get the MKIIs

I think you nailed it very well, though I don't find the treble at all problematical. I've never been a fan of very present highs, so they suit me fine. I think your review would apply to the k240S as well, since the drivers are the same....the ear pads to, I think. The S version can still be had at a bargain price on ebay if you search for them. I agree, it's all about the mids and a fairly well balanced presentation otherwise, other than the over done mid and upper bass. The upper bass bloat bothers me more than the mid bass....i thinks it's what accounts for the slightly 'muffled' sound. But yeah, the mids are 'velvety'....a very apt word to describe them. Try them with Sinatra or some other great jazz vocalist and they really shine. I've heard a lot of phones over the years, and I still come back to the k240s for a relaxed listening session with those velvety smooth mids. Another plus....they're extremely comfortable for prolonged listening. In their price range I doubt there's anything that can give you a midrange anywhere as enjoyable as those AKGs. I've yet to try the K141/2 version...some say they're even better....less 'muddy'.

nice review! will it overthrown HD598 ?

I auditioned the HD598 a few weeks back, though I didn't get to spend much time with them. Based on my initial impressions, the K242 HDs are roughly on par with the HD598s (though it must be said that the Sennheisers seem to be much more durable than the AKGs); The mids on the HD598s are warm, much like the K242s, and the bass is slightly less overwhelming (around the level of the K271's bass). I'd forgotten entirely about the treble :P
 
Cheers!

Sennheiser have HD500-series upper earcups crack problems. I think AKG still way more durable than Sennheiser's cracks.
Which sound character you more pleased with, HD598 or K242HD?

It depends on what I'm listening to, really. I went with the AKGs because, at the time of purchase, I happened to have developed an interests in Jazz and vocal-driven music. I believe that AKG headphones in general excel in these genres, though they leave quite a bit to be desired with my favourite genre, rock. Their performance there is still rather good, though. Pop,rap, and hip-hop benefit from these cans' mid-bass bump.
 
As for the  Sennheisers, I find that they excel with instruments. Vocals are a tiny bit worse than on the AKGs, but that could just be my preference for warm sound signatures. Anyway, the HD598s seem to excel for orchestral and the like, while their performance with pop, hip-hop, and techno is... good. The total opposite of the K242 HDs, the treble on the HD598 is actually quite harsh, which makes rock sound more exciting and lively. 
 
But as always, I'm quite opinionated with my headphone preferences. The only real way for you to decide/find out which cans are better would be to load your music onto a decent portable rig and audition both cans yourself.
 
I'm wishing you the best of luck in advance.
 
Cheers!

I have the k240s and used to have the k271 and I can say for sure that they'll suffer no cosmetic breakage. I get the feeling you can throw them across the room onto the bed and they'll be fine. They're the sturdiest pair of headphones I've laid my hands on.
 
I haven't given my k240 a good listen lately cuz I've been mobile for the past month, but I support what you said in the review. A very nice pair of headphones indeed; maybe try a bit of EQing to boost the treble a bit =)  However, I don't think it's exactly fair to compare it to the hd598 as it costs over twice as much as I got my k240s for..
 
I haven't had the chance to try the 598s extensively.. maybe I should go give it a listen later today
