Mic arrived quickly. Calibration software was easy to install. Calibration process took some time but directions were clear and easy to understand. Applying and adjusting the calibration was easy. The difference in sound is amazing. I started with a good set of 6.5" monitors. It now sounds like I have ultra flat 8" monitors. I still can't believe the sound is coming from my speakers. Easily worth the price. Highly recommended to anyone serious about mixing and producing.
