Following the comments which recommended it for the Parrot Zik I bought this case. I confirm that it is possible to store the Zik, but only by tilting through the headphones, causing them to stand on the side of the pads, and may distort over time (even if they are " shape memory "). The storage net is positioned vis-à-vis the earphone side, which are thicker, so not really make sense because you can not fill it too. And as the net is not stretched by a resilient against the wall, it does not retain Elements that would rank them.
Despite all possible and affordable solution to protect your Zik headphones, next to the price of housing sold by dedicated Parrot.
