I hope I have not handled the connector wrong, but when I read other reviews by me so it was not just me that.
If you have the cap is detached from the first connector connecting the cable to the contacts no longer a problem thanks to two small screw. Insert the plug-part back in the sheath has it works easier than taking out (just push in)
The connection to the speaker was then ultimately no longer a problem and the plug has served its purpose.
It should be noted in any case that the adapter cable to only 1.5mm cross-section "swallows", the bottleneck is at the entrance of the adapter but made of plastic and can be combined with a small knife if necessary slightly wide.
Conclusion: handling somewhat difficult, high but otherwise fine - indeed have to suffer a bit, the plug in the expansion of contacts, he has good sheathes.
