Headphones Upgrade


I’m currently using old Sennheiser HD518 headphones for my home playing. In the Archetype: Gojira, the clean tones are pretty good, but when I add heavier distortion (especially with the 3rd amp), it feels like I can hear some artefacts.

Do you think, is this limitation of my current headphones and upgrading them to some current model could help? If so, could you, please recommend some brands/models?
