Is the Sennheiser HD 600 still worth buying after 25+ years?

Across the reviewers we read, the HD 600 remains a consensus reference for midrange accuracy and vocal/acoustic timbre, with replaceable parts and long-term durability cited as major strengths. The honest caveats: limited sub-bass extension and a narrower soundstage than modern planars. If you want a tuning reference rather than a wow-factor headphone, it still earns its reputation.
