The Bang & Olufsen Beoplay H95 is 12Ω with a sensitivity of 101.5 dB/mW, which is 120.7 dB/V. To reach 100 dB SPL — genuinely loud, louder than most people listen — it needs 0.71 mW, or 92 mV across the drivers.
That puts it in the easy category. A phone, a laptop headphone jack or the cheapest USB dongle will drive it to painful levels. Of the 280 sources in the database, 277 have at least 10 dB of headroom and another 3 have enough. The cheapest portable source that does the job is the Apple USB-C dongle (US) at $9.
Sensitivity here is in dB per milliwatt. Why the unit matters.
Bang & Olufsen publishes this directly as 101.5 dB (1mW @1kHz), per milliwatt, so nothing was converted.

Bang & Olufsen prints 20–22,000 Hz for the Bang & Olufsen Beoplay H95, under the heading “FREQUENCY RANGE”. Source: bangolufsenrmaskillgohel.blob.core.windows.net.
No tolerance is printed with it, so “20–22,000 Hz” says nothing about how loud this headphone actually is at 20 Hz.
Only what the maker printed; maker by maker.
| Level | What it is | Power | Voltage | Current |
|---|---|---|---|---|
| 85 dB SPL | quiet background listening | 0.02 mW | 16 mV | 1.4 mA |
| 95 dB SPL | normal listening | 0.22 mW | 52 mV | 4.3 mA |
| 100 dB SPL | loud listening | 0.71 mW | 92 mV | 7.7 mA |
| 105 dB SPL | very loud | 2.2 mW | 0.16 V | 13.7 mA |
| 110 dB SPL | peaks on dynamic music | 7.1 mW | 0.29 V | 24.3 mA |
Most people listen between 75 and 85 dB; the 100 dB row leaves room for peaks.

Hiss. At 120.7 dB/V these are sensitive enough to reveal a source's own noise floor. The noisiest source in the database, the Schiit Mjolnir 3, would put its hiss at roughly 29 dB SPL in these headphones — clearly audible in quiet passages. Check your own source.
Output impedance. At 12Ω these want a source output impedance below 1.50Ω to satisfy the one-eighth rule; 41 of the 192 sources that publish one miss it. Check yours here.
