I bought the headset, because I had lost enclosed with my smartphone. Flew in that this is a cheap plagiarism, but was pleasantly surprised. The same good quality as usual from Samsung usual.
Now I was looking for the headset for a week ... it had found today, as I had washed my shirts - it was washed at 40 °. Lo and behold, it works perfectly, is beautifully clean and pleasant smell of fabric softener.
I can say that this headset has passed my unplanned robustness test successfully.
CONCLUSION: buy recommendation!
