I'm not an expert but here's what I can say about this new AKG headphones: packaging as a whole is really any and did a little cheap. The helmet meanwhile has a beautiful look, despite the massive presence of plastics. The arch is lined with a rubber band to provide more comfort around the head. It is easily adjusted and easily fits around every head. It folds easily and fits without having to force in the cover provided in tissue. The helmet is really light as it weighs only 133g. The audio cable is detachable which is no more significant context as well as the remote control for influencing the volume or pause playback (tested without problem with my XPERIA M2) But let's get to the point: the sound. Without being an expert, I repeat, I can not too wrong to say that the sound of this headset is very well made, that the bass is very present without the mids and highs are forgotten. Power is also the rendezvous as well as isolation from outside noise which is pretty impressive for a headset of this price. Even after 1 hour of listening to the headset remains comfortable and is forgotten. A LITTLE WHILE detail before concluding: the headphone remote is not yellow as shown black but making it less visible. In conclusion: apart from any packaging this new AKG headphones is a pleasant surprise nonetheless sold to my senses a bit expensive.
