I am not an engineer, and certainly not a professional speaker. I bought this mic because of the reviews here and use it to comment on product videos or add an audio track spokesman. For this purpose, I use changing programs (Audacity, GarageBand, ...). At first I was shocked how bad my sound recordings, but here the fault lies with the user. Once set up the programs clever and everything is fine. I've found with this microphone in combination with an Popkiller a constant quality. In both small and large spaces to get well clear. Ambient noise I make very rarely fixed. Sure - if in the next room, the phone rings, the recording is useless. So far I am very satisfied and have received exactly what I hoped for, due to the reviews.
