Short answer: the Xiaomi Sound Outdoor. It ranks #44 of 144 medium speakers by sound quality, rated 3.7/5, at $54.99; the Ultimate Ears Roll 2 ranks #130, rated 2.2/5, and costs $100, so there is little reason to consider the other one.
What the Xiaomi Sound Outdoor does well: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Watch for: Its 60Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
Why pick the Ultimate Ears Roll 2: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. The tradeoff: Not stereo.
Worth knowing: the Ultimate Ears Roll 2 has been discontinued and is hard to find new at this point.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Ultimate Ears Roll 2 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.
