It's a nice mic and you can get a calibration file on this exact microphone by plugging the serial number into Dayton's site.

Nice mic for room testing

It will capture a very natural sound as well, but it's still not a very good recording mic.- Similar products used: Sound Professionals binaural mics

This mic is not expensive and comes with its own calibration file

Overall, good mic and does the job.

great mic for a great price

And it is a very accurate mic for measurement.

Worked great for room measurement, and honestly also is a fantastic little mic for capturing an acoustic guitar and vocal scratch track (or for other idea archival purposes since you only have to set up the one mic and hit record).

This mic will be awesome if it also can be used for vocal, else it will be underused after you are done treating your room

Great price for a great mic
