Both are portable amplifiers, $650 against $829. 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?
On raw power they are level: each reaches 100 dB on 566 of the 567 non-electrostatic models here.
| Specification | Chord Mojo 2 | Shanling H7 |
|---|---|---|
| Power into 32Ω | 564 mW | 450 mW |
| Power into 150Ω | 145 mW | 96 mW |
| Power into 300Ω | 90 mW | 48 mW |
| Power into 600Ω | 45 mW | 24 mW |
| Output impedance | 0.06 Ω | 1.0 Ω |
| Output noise | 2.7 µV | 1.5 µV |
| Price | $650 | $829 |
| Headphones it reaches 100 dB on out of 567 | 566 | 566 |
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.
On power they are interchangeable across this whole database: there is no headphone here that one reaches 100 dB on and the other does not.
15 headphones are left alone by the Chord Mojo 2 under the one-eighth rule but coloured by the Shanling H7 (64 Audio Nio, 64 Audio Volur, Campfire Audio Andromeda 2023, 12 more).
11 headphones stay below the audible-hiss threshold on the Shanling H7 but cross it on the Chord Mojo 2 (64 Audio Fourte, Campfire Audio Andromeda 10, Campfire Audio Andromeda 2023, 8 more).
566 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: Chord Mojo 2 and Shanling H7. Or put either against your own headphones in the source comparison tool.
