no question ... EDIT TOP !!!

Delivery: Very fast (4 days earlier than expected)
Comfort: a matter of taste ... I think is very good, as the "Leather" is very pleasant and you can adjust the EP650 perfectly on the head with the ironing.
Optics: a matter of taste ... in my opinion also very good, as they damn classy yet modern look (bordo red).
Battery: For three days not charged (after / before school during the breaks used) and still fully functional.
Sound: The bass is excellent. The sound is overwhelming in the price range.
Microphone: Three times used and the interlocutors were always impressed by the crisp sound.
Value for money: In my opinion, no question ... for about 40 euros you can find nothing else.

Conclusion: The sound is of course not as pronounced as headphones from 400 but these miracles headphone promise for the low price and huge can keep up with one or the other Sennheiser headphones in the low three-digit price range. I can not understand the bad reviews ... Ex .: When you get a broken device can it ever within the next 14 days to return (regulated by law), and often can not help the company. If you know of yourself that you can roughly handle such devices then you should order now to the sleeve ... And not to fall off the multiple-retailers accuse you produce a bad product.

All in all I'm thrilled and would recommend to 200% headphones !!!

EDIT:
Hello again,
I wanted to add that the headphones no longer respond to the Equalizer for a few weeks. Did it with a number of attempts but nothing has happened ... This is a shame because I have no ordinary bass more :( Many recognize the equalizers not at once that a headset is connected. Has anyone might have a similar problem and can help me?
Otherwise, the headphones still fulfill their job perfectly!
If I still get this problem under control, they are again 1A ++)
