I slightly Rabotte the edge to get it into the rather small notch of the MM550.
FYI I used a disposable razor to have a roughly flat on the headset connector (the plastic is well cut like that) and a nail file to "cleaner".
Well run and with a cutter blade it should also work, you get the idea :)
Pictured my cutting.
The 1m cable is on the move (connected to the phone in the pocket or laptop computer), I'll take me a cable of 1.5m from the same vendor (; refRID = 19AME6RC5MYN5WAPJBB6) to allow it to "fixed ".
Fast and consistent delivery, average cable, it seems solid and me no problem since I have it, please :)
