AKG K-371

Značka AKG již není rakouská, přesto kvalita zůstává, alespoň dle mého hodnocení, zvuk je vyvážený, sluchátka perfektně těsní, využívám je na nahrávání v domácím studiu, bohaté příslušenství, velké náušníky, které sedí i na velké uši. Určitě se objeví kritika, přesto si myslím že záleží na každém jaký zvuk je mu nejpříjemnější, pro mě je to zvuk značky AKG. Nevyplatí se kupovat o polovinu dražší v této cenové kategorii je jen málo takto kvalitních sluchátek. Vřele doporučuji, pokud posloucháte CD kvalitu, jsou skvělá, pokud jste hifi člověk a posloucháte například SACD bude potřeba pořídit dražší sluchátka. Přesto skvělá univerzální volba pro mnoho použití ve vysoké kvalitě. Sice firmu vlastní již firma HARMAN, ale kvalita stále znát. Lepší zvuk než AKG studio k240.

What I immediately noticed after putting them on was that they might just be the most comfortable closed back pair of headphones I've ever worn. The earcups are simply flawless and while the padding on the headband looks pretty thin I don't have any complaints.
I was also really surprised by their built quality, having heard about issues with this model. I would go as far as to say that it is by far the best built AKG headphone currently in production, although not quite as well as the now discontinued K550 series. However just about everything looses to the k550 series when it comes to built quality. Overall they feel sturdy and use high quality materials with a great fit and finish. That being said the hinge definitely feels like an obvious weakpoint and I would have preferred it if they sacrificed a bit of portability (rotating the earcups inwards really doesn't make them much smaller) for durability, however only long term use can tell how well they'll hold up.

I was significantly less impressed with the sound. They are advertised as professional studio headphones and while they are useable for tracking thanks to their decent isolation, their sound signature makes them simply unusable for pretty much everything else you would do in a studio, as they might be the least neutral headphones I own.
The bass is quite elevated, however they somehow manage to be both bass heavy yet lacking punch in the low end. This leads to comparatively recessed mids making most instruments and vocals sound somewhat distant and muddy. This wouldn't be the end of the world, however it is exacerbated by a massive dip in the upper mids/low treble completely burying many harmonic frequencies in the mix, which causes the already quieter mids to sounds like they were recorded through a pillow. There is a slight emphasis on the mid treble but this does little to add detail or clarity and just emphasises cymbals.
Overall these are terrible for mixing purposes as the frequency response almost feels like it was purpose made to bury potential issues in the mix.
That being said they don't sound terrible when listening to music and they are very forgiving to bad mixes as they bury mistakes and are probably quite decent for bass heavy music like EDM perhaps. However with a lot of songs it can feel like you're being bombarded with bass instruments and cymbals through the headphones while other instruments and vocals are being played through a separate speaker on the other side of the room, which can make for a very straining and uncomfortable listening experience.
They do however have a great soundstage and god imaging for a closed back.

If you want extremely comfortable, well built headphones with good isolation and an ok sound for a reasonable price I can highly recommend them and I'll keep them for these purposes however I will definitely apply an EQ for certain music.
If you want headphones for professional work, you should stay away from these. The same probably goes for people who mainly value sound quality that being said audio is highly subjective and if you get the chance to test them you might end up liking the sound signature.
I would definitely consider them an overall step up from the similarly priced ATH M40x/m50x but I think one of the DT 770 models is still the way to go if you want a closed back in this price range and don't need a detachable cable.
