Short answer: the Teufel Boomster 2021 for balance, the JBL Boombox for features. The Teufel is described as pretty balanced and slightly warm, with boosted mid bass compensating for bass that is not as deep as higher-ranked speakers. The Boombox links Connect+ across up to 100 speakers, but its treble is not very smooth.
Buy the Teufel Boomster 2021 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Blast instead.
