I received AKG K242 HD headphones today and when I dissasembled them I was in shock because I expected different driver.
Looks like there is absolutely the same driver as in K530 Ltd. I don't know how they will sound because they need need burn-in. I wanted to give K530 to my mom so I don't care much. These K242 are more comfortable, though.
What's more. I read in service manual that these headphones:
k141mkII, k142 hd, k171 mkII, k172 hd, k240mkII, k242 hd, k271 mkII, k272 hd
use the same driver 2606B00050. There is no info on K530 but the driver looks the same and ~26mm. Old K240 drivers look different.
In the end, the most important thing is how it sounds. But looks like rip-off to me.
