sensitivityを理解する
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.
この対戦In this spec, ATH-M50xBT2 and Major V are effectively tied at 99dB — buyers can treat them as equivalent on sensitivity alone.
用語集
sensitivityとは？
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.
