When I got my new Audio-Technica ATH-M50xBT headphones I did some research so I could set them up for studio monitoring – which basically means endeavouring to get a totally flat frequency response with no colouration. These headphones are known for having a slight bass lift.
I found a great technical reference page:
Although I could use one of the standard Logic plugins, I found the EQ560 plugin by Red Rock Sounds:
This is a very nice graphic fixed band equaliser.
So I now have this on the Logic master output, and can switch it in whenever I’m monitoring and mixing on these headphones.
