I have a case for my Sony Ericsson MW600 Bluetooth receiver and my Sony In Ear Headphones thought and it all fits into just fine and is well protected. Nothing is pure crushed or lost in it. The processing is in my opinion very good and stable. Of course, it does not hold any force was, however, for.

A nice side effect: the two things are now kept finely clean in one place.
