K-52 : You get what you paid for

PROS:

-Very lightweight and comfortable;

-Decent quality for 30€, but do not expect "high quality" as I saw many people (and AKG) writing;

-2.5m cable, which could be a pro but also a con :D ;

-Decent bass for the price.

CONS:

-Very bad isolation;

-Really bad frequency response: highs totally messed up, mids with strange behavior;

-Consequentially, stereo image is pretty messed up;

-Materials do not feel like solid, balanced or strong - they're still acceptable for price range.

I am a master's degree student in electroacoustic composition, ergo: not an expert but not just an enthusiast.

I have to say my recent headphones have been AKG702 and Beyerdynamic 990 PRO, also in these days I am listening in a very great studio (well treated - enormous Genelecs), so my standards may be strongly influenced by this.

So, these headphones are pretty much ok for the money you're about to spend. But do NOT expect a decent isolation, a reasonably fair frequency response, a nice stereo image.

I just thought this pair of headphones would have been something better. Unfortunately it does not satisfy me, so I will send it back.
