I use two interchangeably - Focal Spirit Professional, and Avantone Mixphones. I've tried some others before like Sennheiser (HD280, 650), Westone, and studio classics from Sony and Shure, but they all had their translation issues.
I settled on the Focals and Avantones for a few reasons. 1.) They're similarly "transparent" (nothing is truly transparent, hence the quotes lol) to one another.
2.) I mix and monitor through Focal CMS 65s and 40s and an Avantone Mixcube.
3.) The Avantones have a mono switch built it. Which is great since I record some things in mono (clean, high gain) and some in stereo (delay, reverb), so it's nice to be able to check easily.
Ultimately, I've found them to help easily craft tones that translate perfectly for me since I can pick up on the slightest EQ tweaks. Even more so than through studio monitors and an FRFR.
I'm just curious about what others are using. Or if you're using headphones at all. I know some people prefer not to.
