Perfect for recording my guitar lessons!

This mic I use to record my guitar lessons for several years on a player / recorder Sharp MD MT190.
It allows me to listen to them again during my teacher on my channel or record accompaniments on which I try to improvise.
The sound of the record is really excellent, the breath is barely noticeable and balanced sound, I find it perfect for use that I in fact, nothing to do with the microphone SONY ECM-F8 I bought first given its price much more affordable but whose records were really bad.
I definitely recommend the Sony ECM-DS70P to all those who are likely to have the same use as I'm sure they will not be disappointed.
