Analysis
The Sennheiser HD 800S scores 9.5/10 with 300Ω impedance and 102dB sensitivity. At 300Ω, it benefits significantly from a dedicated amplifier.
The 64 Audio U12t scores 9.5/10 with 12Ω impedance and 108dB sensitivity. At 12Ω, it can be driven directly without extra hardware.
Both headphones score equally. The best choice depends on your full audio chain — use our analyzer to find your actual bottleneck.

A high headphone score doesn't mean your audio sounds great. Your DAC, amp or source might be the real bottleneck.
