All user reviews for the AKG K 422

Based on using for four months: 

<div>
I tested all headphones available to listen to at FNAC. This one was what appeared to be a headphone that does not change the sound and that is accessible for city use.

At the trial I was amazed.&nbsp;

Although they are an excellent value at € 39, they are much better than many others that are much more expensive!

Good - but on the other hand, I did not notice that they leak sound because they are half open (or semi-closed to the pessimists: o) ...
And I listen to the likes Musk - it is hard to escape the bustle of the metro, bah there all the wagon benefits: o /

Even in the office, I kept the volume low because my ipad interfered with my colleagues.
So it's a great headphone but you really have to be careful when you are not using it alone.&nbsp;

</div><div>It is impossible to use it while recording or performing with amplifiers because the headphones leak so much sound that it goes it goes into the microphone or produces feedback.
Too bad, &nbsp;because otherwise they are great! </div>
