Sonarworks offers an excellent product which gives you options to correct and flatten the frequency of your monitoring setup and customise it based on your room and their calibrated microphones and headphones. Even more flexible is you can choose to put it on for system wide listening, or use as a plugin so it only runs in the DAW and not system wide. It really does help knock out some of the troublesome lows in my Beyer Dynamic DT770 Pro. It also helped me make adjustments to my monitors and cut lows on the speakers themselves before measuring again to help flatten the frequency further. It won’t fix everything if you haven’t got a treated room, but even then it can help a little to pull it closer if you have a less than ideal listening environment. It is worth the spend, especially when it goes on sale. When that happens, it is a must have no-brainer. It is my “always on” plug-in.
