Short answer: the JBL Go 3 for pocketability and price, the Miniroll for clarity. The Go 3 is genuinely pocket-sized at 0.5 lbs (209 g), is IP67 rated and survives full submersion in a meter of water for 30 minutes, and costs $39.95, though it has not much bass at all and a strange mids peak. The Miniroll gives good clarity and detail in the mids and highs, but its bass is not quite as deep as the best rated speakers.
Buy the Ultimate Ears Miniroll. It is rated higher for sound quality, and the $10.04 you would save on the JBL Go 3 does not close the gap.
There is a real battery-life gap here: the Ultimate Ears Miniroll is rated for 12 hours, the JBL Go 3 only 5 hours.

Ultimate Ears Miniroll: $49.99 Amazon eBay
Older model: the Ultimate Ears Roll 2 (rated 2.2/5).
Pros: Ultimate Ears Miniroll uses 45.6mm active with passive radiator. Its 279 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection, up to 83dB and mono playback make it a practical option for its intended room or portable use. Good clarity and detail in the mids and highs, with a warmer balance than most speakers its size.
Cons: There is no companion app. No EQ adjustment. Bass does not reach as deep as the best-rated speakers.
