The plug of the adapter leads to the cell phone has been designed for the "introduced" to the metal is somewhat wider than the original (headset from Samsung)
and then press on the awkward headphone manhole cover (or how to call it otherwise ???) of the mobile phone.
Since the Dremel was within reach I quickly at one edge of the plug ca.2mm plastic ground and now it fits without interfering.
Now I can safely use my Sennheiser headphones on mobile phone, which also sound good with the adapter and the
Radio function can also be used but the reception is slightly worse than with the original headset.
So who does not shy away two minutes work with the Dremel (or smaller file) or to whom the cover on the phone does not matter, can "strike" here. ; O)
Four stars I forgive anyway because the adapters (now) does as it should, the price is ok and sometimes I like to tinker. : O); o)
