The SMSL C200 is a desktop DAC/amp at $219. It delivers 1.3 W into 32Ω and 139 mW into 300Ω, which ranks it 66 of 280 for raw power among the sources in this database.
Measured at 100 dB SPL it has comfortable headroom on 566 of the 567 dynamic and planar headphones catalogued here and enough but not generous on 1. Power is published at 16Ω, 32Ω; the rest of the table is derived from those figures. The published figures describe the balanced output, so the single-ended jack will put out less. Output impedance is published only in words, not as a number. Output noise is not published, so the hiss estimate cannot be run.
The manufacturer publishes 2.6 W into 16Ω, 1.3 W into 32Ω. The rest of the table is worked out from those.
The published figures describe the balanced output. A single-ended jack on the same unit will put out less — usually about half the voltage and a quarter of the power.
Derived rows hold output voltage steady, as an amplifier does (method).

The manufacturer does not publish an output noise figure for this source, so there is no hiss estimate here. If you have a measured figure, the hiss calculator takes it.
The manufacturer answers this question in words rather than in ohms, which leaves nothing to compute with. Without it, nothing here can say how this source will behave with a multi-driver in-ear.
With a measured figure, the checker works out the consequence.

Of the 280 sources here, 15 do everything the SMSL C200 does as a headphone output: reach 100 dB on every headphone it reaches. The cheapest of them is the Schiit Magni Heresy at $99, against this one’s $219 — $120 less, and a desktop amplifier rather than a desktop DAC/amp.
The cheaper one also publishes an output impedance, which the SMSL C200 does not — so on the paperwork it is ahead, not merely level.
This counts the headphone output only; inputs, converters, the volume control and the build are outside it.
