Best Over the ear headphones under 3k

Hi guys!

My ears are kinda big and I need headphones that offer comfort, maximum comfort. The kind that came on sennheiser studio headphones.

What should I purchase?

My use case is 10hrs of white noise, lectures, music (1.5hrs at best) Currently use a boat 412 but they aren't as comfy.

Is boat rockers 550 plus a safe bet at 1.8k?
