Both are dongles, $22 against $20. This page puts them side by side on the only three things a maker can be held to — power, output impedance and noise — and then asks the question that actually matters: which headphones do they treat differently?
The FiiO SnowSky Tiny B reaches 100 dB on 554 of the 567 models here, the JadeAudio JA11 on 547.
| Specification | FiiO SnowSky Tiny B | JadeAudio JA11 |
|---|---|---|
| Power into 32Ω | 34 mW | 30 mW |
| Power into 150Ω | 7.3 mW | 6.4 mW |
| Power into 300Ω | 3.6 mW | 3.2 mW |
| Power into 600Ω | 1.8 mW | 1.6 mW |
| Output impedance | 1.0 Ω | 0.5 Ω |
| Output noise | not published | 1.7 µV |
| Price | $22 | $20 |
| Headphones it reaches 100 dB on out of 567 | 554 | 547 |
A figure marked not published is missing from the maker’s own material, which is not the same as being good or bad. Where one of these two publishes a number and the other does not, the comparison on that axis cannot be made at all — and saying so is more useful than guessing.
7 headphones reach 100 dB on the FiiO SnowSky Tiny B but not on the JadeAudio JA11 — Kinera Freya Vanir, Moondrop PARA 2, Moondrop VENUS, 4 more.
14 headphones are left alone by the JadeAudio JA11 under the one-eighth rule but coloured by the FiiO SnowSky Tiny B (64 Audio Nio, 64 Audio Volur, Campfire Audio Andromeda 2023, 11 more).
547 of the 567 models here reach 100 dB on both. That is a power count and nothing more; whether either source suits a given headphone also depends on the two lines above.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: FiiO SnowSky Tiny B and JadeAudio JA11. Or put either against your own headphones in the source comparison tool.
