Short answer: the Marshall Emberton II, if you are buying new. The Bogasing M4 ranks higher than it (#28 vs #123 of 164 medium speakers, 4.0/5 vs 2.7/5) but is discontinued, so only consider it used; the Marshall Emberton II is still sold new at $144.99.
The Bogasing M4 is the better-sounding, deeper-bass pick. Super Bass mode gives the most balanced sound. Its bass reaches about 54Hz before falling 10dB, against 62Hz for the Marshall Emberton II. Alan Ross Reviews measured it at 99dB at full volume, against 88dB for the Marshall Emberton II. It keeps a wired aux input, which the Marshall Emberton II lacks. The tradeoff: It sounds a bit harsh and thin.
Why pick the Marshall Emberton II: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It has an adjustable EQ, which the Bogasing M4 lacks. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Marshall Emberton II, since the Bogasing M4 is discontinued and only worth hunting down used.
