Meze POET: how much amplifier do you need?

The Meze POET is 55Ω with a sensitivity of 101.0 dB/mW, which is 113.6 dB/V. To reach 100 dB SPL — genuinely loud, louder than most people listen — it needs 0.79 mW, or 0.21 V 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, 280 have at least 10 dB of headroom and another 0 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.

Where this sensitivity figure comes from

Meze publishes this directly as 101 dB SPL/mW (at 1 kHz), per milliwatt, so nothing was converted.

The maker adds a power recommendation of its own: Meze publishes no power handling and no recommended amplifier power for the POET; the only level-related figures are "Maximum SPL: >130 dB" and "Total Harmonic Distortion (THD): <0.05%" (no SPL or drive level is attached to the THD condition).

Meze prints 4 Hz – 96 kHz for the Meze POET, under the heading “Frequency Range”. Source: mezeaudio.com.

No tolerance is printed with it, so “4 Hz – 96 kHz” says nothing about how loud this headphone actually is at 4 Hz.

Only what the maker printed; maker by maker.

Most people listen between 75 and 85 dB; the 100 dB row leaves room for peaks.

The three ways a source goes wrong

Hiss. At 113.6 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 22 dB SPL in these headphones — clearly audible in quiet passages. Check your own source.

Output impedance. At 55Ω these want a source output impedance below 6.88Ω to satisfy the one-eighth rule; 34 of the 192 sources that publish one miss it. Check yours here.
