Short answer: it depends, the JBL Go 4 for a little more bass and the Miniroll for the mids and highs. The Go 4 adds a little more bass than the Go 3 and fixes the strange mids peak, but it still has not much bass at all, especially with electronic and bass-heavy tracks pushed past about 50% volume. The Miniroll offers good clarity and detail in the mids and highs, with bass that is not quite as deep as the best rated speakers.
Buy the Ultimate Ears Miniroll. It is rated higher for sound quality, and saving $0.04 with the JBL Go 4 does not make up for the sound-quality gap.
If battery life is a priority, the Ultimate Ears Miniroll is rated for 12 hours versus 7 hours for the JBL Go 4.

JBL Go 4: $49.95 Amazon B&H Photo Video eBay
Newer model: the JBL Go 5, ranked higher, rated 3.2/5.
Pros: A little more bass than the Go 3 and they fixed the strange mids peak. Measured bass extension of ~82Hz (-10dB).
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.
