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."
