Just had to research V-shaped and I guess that could be it, though I would have naively assumed the drum sounds would be coming through cleaner if the bass was being boosted. Going to rack up some listening hours to see if my ears just get used to it.

Yeah the more I listen the less outright ‘bad’ it sounds, just different. Well, at least for certain songs. There are definitely some songs just sound outright worse, though some sound better. Why can’t this stuff ever be linear improvements? 😫

See I had read what people refer to as the “Sennheiser sound” so presumed (in my ignorance) their over ears would all broadly sound similar to a certain extent. 🤷‍♂️ Good shout in different device; smartphone has no jack so I’ll try it on my MacBook.
