I was initially excited about the email, elegant design! But the joy did not last long, because to get nich to the headphone jack (Alternative Bluetoot headphones) and after a short time burst at the corners of the envelope parts away until now (about 1/2 year after purchase of the envelope only still behind the aluminum is left. This in turn is very zerkratz and no longer looks really good.
For the low price but still ok, but a shame that you life is so short!
