Short answer: the Miniroll, for $28 more. It ranks #12 of 47 small speakers at $49.99; the Select 4 Go ranks #23 at $21.99.
The Select 4 Go’s whole case is price, described in our notes as quite inexpensive for what you get. Its cons are real: bass that doesn’t reach as deep as higher-ranked speakers, volume that tops out before sound quality holds up, and no built-in mic, so playback is mono unless you buy a second unit.
The Miniroll answers with better clarity and detail in the mids and highs, with a warmer tonal balance than most ultra-portables its size, and its own bass simply isn’t quite as deep as the best-rated speakers.
Buy the Miniroll for the better sound at a still-modest price. Buy the Select 4 Go if the absolute lowest price is the priority.
