khzIn a rather early celebration of my new job I've been shopping. First up, brand new headphones -
AKG K240 Studio, bought from an actual shop in
Skelleftea believe it or not. The shop had a number of headphones available for costumers to try out. The clerk informed me that due to the connections and
mish-mash of multiple headphones and amps the audio clarity will be less then ideal, and he wasn't kidding. A very audible hiss was a constant background nuisance, however it did not increase with volume so I managed to overlook the phenomenon. The clerk recommended the K240 so I tried them first. I'm not sure what songs I was listening to, but the K240 did sound very nice - much more vivid then my old
Sennheiser yet with great clarity and a good "drive" (probably due to the 55 ohms impedance). I've never been much into bass heavy headphones (or God forbid -
EQ enhancement), they usually have a deep but uncontrolled bass at the cost of clarity and resolution - but the first thing that actually struck me with the K240 was the rich and tightly controlled bass. On top of that, the higher pitched notes were really detailed and sharp which gave the K240 a reference-like sound. Reference headphones play music as close as possible to the original recording, not trying to warp or enhance low or high frequencies. As for the K240 some argue that the sound is fuller then the original recording, and hence not a true reference model but most agree that it is well within an acceptable limit.
As with most headphones you need to test different models with the same music player in order to really nail the differences in sound. I did some test with the
AKG and the old
Sennheiser using .
wav rips from the CD Holy Diver by
Dio. The recording quality of the Holy Diver CD from 1983 is not particularly good (I guess no one was surprised by the 2005 remastering - which still sucked unfortunately), there are a few glitches in some of the tracks but nothing major (the grain in "Invisible" and "Rainbow in the dark" for instance). Unfortunately (well, kind of) high end headphones are very unforgiving when it comes to recording quality. Good headphones produces such high detail and resolution that any minor sound or imperfection unfortunate enough to make it onto the recording will be noticed. Low end headphones simply does not have the required resolution in audio quality to reproduce minor imperfections which makes the system smooth out the edges - and also makes the sound less detailed and more "
meh".
Anyways, I listened to the intro of "Straight through the heart" to compare the headphones. The K240 did an admirable job, deep and exact bass in the background with clear guitar riffs up front and drums somewhere in the middle. Very good indeed. Switching to the
HD 215:s the difference was staggering, the
HD's most notable feature in the intro was the
rampid bass line. Left
uncontrolled, the bass lingered in a slithering echo to the paper flat guitar riffs over a grainy
soundscape. I was amazed at the difference, I mean the
HD 215 isn't exactly
Sennheisers flagship
but in comparison to the K240 they really sounded like crap. The 215 does have a lower impedance which probably explains the lack of drive to the sound but that also makes them play louder then higher impedance models at the same volume setting from the source player.
The K240 sounds great and due to it's constant level of competence it's easy to take the incredible sound for granted. There are however songs that produce that "wow" sensation every time. One of which is "Feel for you" by
Nightwish (.
wav rip). The song starts with a heavy bass track, sounds deep and beefy through the K240, which contrasts nicely to the crystal clear and sharp sound of the strings which follows. The bass plays in the background as the strings takes over and the song takes off.
As for the construction the ear-cups are connected through the two wires which holds the sound cables and by the headband. This makes the headphones very flexible and unlikely to break. There are two strings on each ear-cup, connected between the headband and the ear-cup, which in turn is mounted on springs (or something similar) which puts the strings under tension. This makes the headband self adjusting, just put the headphones on your head and place the ear-cups over your ears. Very smart and very comfortable.
In
summation I really like the
AKG K240 Studio headphones. Unfortunately you'll need a high quality music player coupled with a
high quality recording, otherwise all the minor imperfections just might drive you mad. Since these are semi-open headphones the noise of the outside world is not as reduced as with closed 'phones and the outside world will also hear more of your music - but then again, it's better then with open headphones (for best quality open headphones is the way to go, but due to the lack of isolation open headphones require a quiet environment). I
highly recommend the K240's and considering the price range, it's an absolute
bargain.
