Widely called one of the most powerful pocketable units of its day. Reviewers drove an Audeze LCD-4, Sennheiser HD 800 S, HIFIMAN HE1000-class planars and an HD 650 from the balanced or 6.35 mm output, most on medium gain, and Headfonia even got usable volume from an HE-6. The limits sources name are the hardest loads — the Susvara, the Abyss Diana TC and fully opening up an HD 800 S or MDR-Z1R — and FiiO's Q7, which doubles its output on mains power, wins the raw-power comparison.
“Gram-for-gram, Shanling’s H7 is one of the most powerful portable units that passed through our hands, eclipsed only by FiiO’s transportable behemoth, which provided a little bit more grunt.”
Sandu Vitalie, Soundnews
“Less efficient headphones such as the Abyss Headphones Diana TC also sounded a little too polite and dynamically soft for a convincing pairing also.”
Marcus, Headfonics
“新影音在试听完后认为H7虽然能够推动这些设备,但是要推好并且完全推开的话还是还是不大够。”
新影音 (grd125), Zhihu — on the HD 800 S and MDR-Z1R: it can drive them, but not enough to open them up fully
Measured
Shanling rates 28 / 112 / 450 mW into 32 Ω single-ended across its three gains and 87 / 348 / 1,300 mW balanced (its launch notes say up to 1.2 W), with under 1 Ω output impedance on both outputs. No independent bench has verified these figures.
vs. listeners — A Head-Fi showcase owner found IEMs and headphones of 16 Ω or less lost control and blamed the output impedance; Shanling specifies under 1 Ω and a Russian reviewer called it close to zero, but no one has measured it.
