Short answer: Ultimate Ears Miniroll is the better small-speaker choice for midrange clarity, while Bose SoundLink Micro 2 makes its case with compact IP67 durability. The Miniroll has a warmer, more detailed presentation but does not reach as low as the leading ultra-portables; Bose lacks the same clarity.
Buy the Ultimate Ears Miniroll if clearer mids and highs matter more than maximum bass.
Buy the Bose Soundlink Micro 2 if a compact IP67 build is the priority.

Bose Soundlink Micro 2: $129.00 Amazon eBay
Older model: the Bose Soundlink Micro (ranked lower, rated 3.5/5).
Pros: IP67 rated, survives a 1m dunk for 30 minutes. Compact fabric strap for clipping to bags/bikes: replaces the 1st-gen’s hook clip, which was prone to breaking. USB-C charging. Surprisingly good bass when mounted outdoors, like on a bike.
Cons: Lack of clarity. Overly boosted bass that causes some thudding, and can overdrive/distort at higher volumes: worse in this regard than the 1st-gen model. Overly boosted treble, turn down bass and treble in the EQ. Falls clearly behind the Tribit Stormbox Micro 2 on bass depth, cleanliness, and loudness.
