Soundcore Boost “upgraded” 2021 vs Marshall Emberton III

Last updated: October 12, 2026

Short answer: the Marshall Emberton III, if you are buying new. The Soundcore Boost “upgraded” 2021 ranks higher than it (#5 vs #126 of 175 medium speakers, 4.4/5 vs 2.7/5) but is discontinued, so only consider it used; the Marshall Emberton III is still sold new at $129.99.

Soundcore Boost “upgraded” 2021 vs Marshall Emberton III

The Soundcore Boost “upgraded” 2021 is the better-sounding pick. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. Watch for: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.

The Marshall Emberton III is the longer-running pick. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 32 hours of battery against 12 for the Soundcore Boost “upgraded” 2021. It links with other speakers (Marshall Stack), which the Soundcore Boost “upgraded” 2021 cannot. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.

Buy the Marshall Emberton III new; the Soundcore Boost “upgraded” 2021 is no longer sold new, so it only makes sense as a used find.
