The Shanling M3 Ultra is a portable player at $479. It delivers 140 mW into 32Ω and 15 mW into 300Ω, which ranks it 180 of 280 for raw power among the sources in this database.
Measured at 100 dB SPL it has comfortable headroom on 507 of the 567 dynamic and planar headphones catalogued here, enough but not generous on 49, only marginal on 6 and not enough power for 5. Compact player with both jacks and published power at one load. Two gain settings, both rated.
The manufacturer publishes 140 mW into 32Ω. The rest of the table is worked out from those.
The balanced output is rated separately: 260 mW into 32Ω through the 4.4mm jack.
Derived rows hold output voltage steady, as an amplifier does (method).

| Load | Power | Status | How it was arrived at |
|---|---|---|---|
| 32 Ω | 140 mW | Published | the manufacturer publishes this figure at this exact load |
| 150 Ω | 30 mW | Derived | beyond the published loads, holding output voltage constant — which understates rather than flatters |
| 300 Ω | 15 mW | Derived | beyond the published loads, holding output voltage constant — which understates rather than flatters |
| 600 Ω | 7.5 mW | Derived | beyond the published loads, holding output voltage constant — which understates rather than flatters |
Easiest to hardest to drive, with headroom at a 100 dB SPL peak.

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.
At 1Ω output impedance, the one-eighth rule says this source suits headphones of 8.0Ω and above. 15 of the 567 models here fall below that. Most of them are multi-driver in-ears, and the mismatch tilts the frequency response audibly rather than subtly.
| Source | Type | Price | Into 300 Ω | Output impedance | Output noise |
|---|---|---|---|---|---|
| FiiO KA11 | USB dongle | $29 | 22 mW | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | Bluetooth receiver | $59 | 10.0 mW | 0.6 Ω | 1.0 µV |
| FiiO KA3 | USB dongle | $79 | 14 mW | 0.5 Ω | 1.7 µV |
Of the 280 sources here, 43 do everything the Shanling M3 Ultra does as a headphone output: reach 100 dB on every headphone it reaches and stay inside the one-eighth rule wherever it does. The cheapest of them is the FiiO KA11 at $29, against this one’s $479 — $450 less, and a USB dongle rather than a portable player.
The cheaper one also publishes a noise figure, which the Shanling M3 Ultra 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.
