How can I use the Vibez to record with a mic?

[Schiz]

Hi everybody,

I have recently got the TrekStor Vibez, and so far everything is ok. However I was planning to get a quality microphone so that I can make good recordings, but it simply doesn't work. By doesn't work I mean that I plug the microphone(I tried several ones, including simple ones and expensive ones) into the earphones hole(which from what I understood is the line-in) and then I record using the line-in option(high quality).

All I hear when listening to it afterwards is some electric noises(i.e. it's not that it simply records it very weak). The Voice(internal mic) works ok. I don't know so much about this stuff, so please bear with me. Am I doing something wrong, or is there something I'm missing?

Thanks in advance,
Schiz
