The product itself is unfortunately totally useless. Immediately after opening the shipping package falls on a pungent smell, even though the case is still in an unopened plastic wrap. You tear open the plastic on now, is a counter breathtaking stench cloud. This is something I've never experienced.
According to the tips of the predecessor I have the case open aired on the balcony for about 3-4 days. The stench is better, but remains on the product.
I have disposed of this case today and can not recommend buying. The headset itself fits the way just as straight as pure.
