Beyerdynamic DT 900 PRO X vs Sennheiser HD 6XX
Both scored on the same six factors, priced on what you actually pay including delivery, and each claim linked to the source it came from. Prototype data — prices and retailer stock are a fixed demo snapshot from 28 July 2026, not a live feed.
Take the Beyerdynamic DT 900 PRO X unless you need price fairness.
The Sennheiser HD 6XX scores highest at 8.7, but it costs 30,00 € more than the Beyerdynamic DT 900 PRO X, which scores 8.6. That premium buys you price fairness — 1.6 points of it. Worth it if the classic Sennheiser sound at the lowest price it has ever had describes you; otherwise it is money you keep. Watch out for more expensive than the DT 990 it replaces on the Beyerdynamic DT 900 PRO X.
