U12t vs ER4XR

Entender sensitivity
Sensitivity tells you how much volume a transducer produces per unit of input power. A 100 dB/mW headphone hits 100 dB SPL with 1 mW; an 85 dB/mW headphone needs ~32× more power for the same volume.
Comfortable listening
- Conversation / background music — 60–70 dB.
- Engaged listening — 75–85 dB.
- Loud / hearing-damage zone (sustained) — 90+ dB.
Pairing with sources
A phone's headphone-jack DAC outputs ~25 mW into 32 Ω. With a 100 dB/mW headphone, that's 114 dB peak — plenty. With an 85 dB/mW, you might only get peaks around 99 dB — comfortable max, no headroom for transients.
Este dueloU12t's 115dB is roughly 17% higher than ER4XR's 98dB (a 17dB gap). Whether that gap is noticeable depends on workload — small percentage gaps rarely change day-to-day experience, while gaps of 20% or more usually do.
¿Qué es sensitivity?
How loud a headphone or speaker plays at a given input power, expressed in dB/mW (headphones) or dB/W (speakers). Higher sensitivity = louder at lower power.
