Playback time (measured)iReviewer-measured playback per charge. Volume, lighting, sound mode, firmware and connection belong in the source note.

9.13h12Measurementsoundguys.com/marshall-emberton-ii-review-117005Read 23 October 2026SoundGuys standardized battery test: 9 h 8 min, stored as 9.13. Firmware 14.0.35, app 3.2.4. The review gives no test volume. SoundGuys' public method plays music peaking at 75 dB(SPL). Far below the maker claim of 30+ hours. Labo Fnac reports almost 17 h and Delamar reports 30+ hours at low to medium volume, so results depend on volume.

Max sound pressure (measured)iReviewer-measured maximum SPL. Distance, test method and power source belong in source notes.

87dB17Measurementleclaireur.fnac.com/test/120210-test-labo-de-la-marshall-emberton-iiRead 23 October 2026Labo Fnac test of 23 August 2022: output reaches 87 dB at 100 Hz, almost nothing at 60 Hz. The page gives no microphone distance or distortion limit. Labo Fnac's BOOM 3 test states 50 cm and 10 percent distortion. The value equals the maker's 87 dB SPL at 1 m claim, so check it.
