I’m a big Focal fan and I’d definitely consider the Clear MG and Stellia for this list. Agree that the Utopia is heavy for an all-day headphone. That said, I’m retired now so all-day wear is not a big consideration for me these days. Back when I was still working though, I would swear by the Shure SRH1540 for long sessions. The sound is not as good as my Focal cans and, despite being closed back, their isolation was not as good as others. However, they were super light and the fabric ear pads made wearing them continuously reasonable, so those were the ones I used the most frequently in the office.
I still have the Shure headphones, but Utopia and Stellia have knocked them off the regular listening rotation. That said, I think I’ll break them out tonight for a spin!
