Unfortunately tested Did the micro only one hour and then re-wrapped. After some trial and error what is going on, I then realized that the plug of the microphone caused in the socket properly loud noise. The plug is so "sensitive" that moving the table or fine movement range on the cable. This truly minimal movements are enough apparently, that the micro-right causes severe noise. When I try to remain perfectly still, but then supplies the microphone from a relatively good quality. But unfortunately it is only slightly better than my headset. I did test shots with Audacity and clipped the micro to the arm of the headset so that it ziehmlich exactly has the same position and distance as the headset microphone. It sounds almost identical. When I talk louder, less ambient noise or background noise can be heard on the Speedlink. But otherwise the same.
Unfortunately, I had partly correct blatant, even fiepende noise through the defective connector.
Absolutely useless!
I will then probably soon I can make decent voice recordings to a t.bone SC440 or a similar grab it.
I bought the part only because there were several videos in Youtube where the quality of the micro quite well came over. I do not know whether what has changed in the part or if my headset is actually not at all that bad as I thought.
