My background: Audiophile since my teen years in the 1970s, professional broadcaster since 1978. I've spent many years talking on and listening to mics. I'll be the first to admit that my hearing's high end isn't what it used to be, but I can still recognize that this mic provides excellent sound quality and is a great value.
I produce a weekly podcast of sorts, and I've been using a voice booth at the TV station where I work to do the raw recording, then take the file home for editing. That's rather inconvenient, so I got to thinking that I should buy a USB mic to use at home. The reason I picked this model is because it is available for local pickup, was on sale at $129, it has a headphone output, and it looks nice.
Now that I've brought it home, I can add to the list that it has great build quality, and excellent sound. I'm sure that true audiophiles could pick at real or imagined flaws all day long, but for basic, clean vocal recording into a PC, it does an impressive job at a low price.
I recorded several voice samples at home, and compared them to some recordings from the TV station voiceover booth. Although there is a slightly different coloration in the frequency response, the Samson G-Track Pro compares quite favorably. In fact, if I were not doing A-B tests, and you just walked up to me one day and presented me with a recording without telling me which mic it was from, I probably could not reliably identify the source. Clean, wide-range sound, reasonably low preamp noise, and surprisingly good shock isolation. The built-in headphone amp sounds very good and can drive low-impedance headphones to a very loud level. I didn't test the instrument input.
I am confident that for any home, or even some professional voice recording scenarios, this mic will do an excellent job at a very attractive price point. I wish they had stuff like this at this price when I was cutting my audio teeth over 40 years ago!
