Update! Glasses just get 1st impression very good. Unfortunately it does not work! ... Shame ...

... Nevertheless advance times 4 stars for design and 1st quality impression.
The lack of functionality I want to vote here until further times by only 1 star deduction until I know how the seller responds.
Should he be replaced immediately and send an OK-unit, 5 stars.
On the other hand, here are possible deductions to 1 star. Look let's ...
What did not go?
1) Glasses can be no more than the PC USB LW recognize. Suspect 3) the problem is.
Glasses were recognized immediately in the first time plugging in, then never again. I played as equal to some MP3s up to test the music quality. Result: good. But unfortunately 2)
2) relatively loud noise at the left earpiece at normal volume (since only the left, I think to myself, it can only be an error)
3) Reset button has no tactile feedback! Dump them?
4) indicator light illuminates permanently fix
5) No flashing when loading

Conclusion: Could be a "very good" product be (Design top!)
Unfortunately, the reset button appears to be the core of evil.
The music quality left something irritates me.

Hopefully have a Monday device, would necessarily have the spectacle OK

UPDATE:
The reaction from traders was exemplary!
The owner contacted me personally via e-mail the same day, and informed me of the complaint process.
Goods will this time of them personally tested before shipped. In addition, there's a small apology gift.
Goods arrived back at short notice. Everything OK now works very well.
Picture day Super, indoors in low light OK.
Sound is also good. For High End Hifi earphones securely enough, but that says a yes even the price. But I am very satisfied! For very soft music a squeak. Once I turn a little louder, but that is gone.
Operating ergonomics and good to very good.
Design very good
Quality is very good
THANKS

Thank you for the fast service. Problems can always occur, but the question is, how to handle it.
