Better than the head Hörerer enclosed bag

I've brought my case for my Jabra Revo Wireless, as included on the headphones only a rugged bag.
The displayed in the pictures 18cm length and width refer to the interior surface. So my Revo headset fits really well in the case and has a little air.
What I, however, do not like so much, is that at the level still have too much space headphones and therefore the case rattles like a child Überrschung.
My workaround is probably an insert of soft foam.

The case is pretty thin walls, which can be felt on the stability.
So you can simply squeeze the Case / squeeze.
Also, the zipper does not make the best impression. This increased slightly during the pull.
Possibly itself is the still over time.

Unfortunately, the end of the sewn network is not due to the Case. Thus is always a gap at the open procedure.
This then leads to the cable or other parts inserted, during transport, fall from the mesh pocket.

In the pictures is the way not to be seen, which is stamped on one of the two flat sides of the word "X-trillion".
