I did not buy the shell. But I am just by looking for a good sturdy cover for my new QC20 because the shell that is not good. But this shell can only get worse in the measurements given here of 7x5 cm. For it must indeed get into the length before at least 13-15 cm to the headphones for the device anhängeden clever inside. The title "Small Hard Case in black for BOSE QC20 In-Ear Headphones" So is a marketing lie, when the hardcase wirlich has the specified dimensions.
