Well, to be honest HD555 are pretty good headphones.

Sennheiser reworked HD500 series a lot, so the sound quality scales with MSRP. Still, I think HD599 sound pretty good, HD599 could sound a bit more warm than your HD555 and have different sound signature.

Try listening HD599 with different device, like smartphone, to make sure that it is not your AV that colors the sound.

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.
