Our take on the AKG K 242 HD

by Kristen Schaub

Professional-quality headphones for work or play
These headphones are perfect for critical listeners who spend a lot of time in front of their home hi-fi system, or even in a professional recording studio. They feature oversized speakers for outstanding performance and incredibly comfortable earcups with a semi-open, around-the-ear design. AKG has been making high-quality headphones for music enthusiasts and professionals for over 60 years, and the K 242 HDs are no exception. They use AKG's patented Varimotion technology, which allows for greater motion of the speakers' diaphragms to produce powerful, crystal-clear sound. No matter what type of music you listen to, these 'phones will deliver sparkling highs, engaging mids, and dynamic bass.

Carefully designed inside and out
The K 242 HD's self-adjusting headband and soft velvet earcup padding gently conform to your head. The single-sided oxygen-free copper cable supports a clean signal from the source to your ears, and comes with a convertible headphone plug that works with both mini- and full-sized jacks.

From the review AKG 242 HD Headphones -- studio quality, indeed
"The AKG 242 HD headphones were a joy to use. I highly recommend them for high-quality listening sources. These headphones will definitely deliver, if the detail's there. And they do indeed deserve the moniker "studio headphones." I'm not sure I'm quite ready to go back to the status quo. There may be a set of AK 242 HD headphones in my immediate future."

AKG K 242 HD

Written By Kris, Texas on Thursday, October 13, 2011
Incredible earphones!!! First unpacked and listened to them for a few hours was very impressed. After reading some reviews about how great they sounded after a few hundred break in hours I couldn't wait I set my computer to loop and connected my headphones and walked away. A week later....WOW what an improvement. Highs are crystal clear, the mids are fantastic and the lows are great (not over-emphasized). If you want tons of bass these are not the cans for you (buy some beats chit), but if you want great quality sound then you will not be disappointed. Word of advice, if you want to listen to these with you iPhone or iPod buy a headphone amp apple devices do not have near enough power to get the great sound out of these. I recommend the cmoy amp from jdslabs.com send him the specs of your earphones and he will costume build your amp for you at a reasonable price. Only gave them 4 stars because a ten foot cord c'mon really?? Put a detachable short cord on and have the ten foot cord as an accessory. All in all great headphones!!

Fits like an OJ

Crutchfield Customer Review (What's this?)
The AKG sound and fit is perfect. Just what I was looking for. Listened to my
music for three hours and never had to just. The auto adjustment headband
works great and more importantly my BIG ears are covered.
Got my recommendation!

Best ive ever owned

Written By SeanP, Rochester, NY on Tuesday, March 15, 2011
Crutchfield Customer Review (What's this?)
I bought these because the bose tri ports I had were showing their limitations as
of late, and wow, I am completely blown away at the quality of these cans.
I put in Clapton Unplugged, playing through my XFI sound card, and the level of
detail was staggering, you can hear the fingers ride on the guitar strings. The bass
is not too strong, but I am also just breaking these in and have not made too many
eq adjustments as of yet. Definitely Satisfied with my purchase.

Great Headphones

Written By Greg, Columbus, Ohio on Wednesday, October 13, 2010
Crutchfield Customer Review (What's this?)
These headphones sound great and are very very comfortable, only complaints is that iPods don't have enough power to drive them and you really need a headphone amp if you want to use them. Also a detachable cord would be nice so that a shorter cord could be used
