Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Bose SoundLink Color II is the better pick: it ranks #125 of 175 medium speakers by sound quality (rated 2.7/5), against #161 (rated 2.2/5) for the Ultimate Ears Roll 2. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79. The Ultimate Ears Roll 2 has been replaced by the Ultimate Ears Miniroll.
The Bose SoundLink Color II is the better-sounding choice. Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. It plays in stereo from a single unit, unlike the Ultimate Ears Roll 2. The catch: Boosted bass on Color II.
The Ultimate Ears Roll 2 is the lighter, tougher option. Thin, flat profile fits easily in a bag or purse. At 0.7 lbs (330 g) it weighs much less than the Bose SoundLink Color II at 1.3 lbs (600 g). It is rated IPX7 against IPX4 for the Bose SoundLink Color II. It keeps a wired aux input, which the Bose SoundLink Color II lacks. Watch for: Barely any bass, rolled off treble off axis.
Buy the Bose SoundLink Color II only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the EarFun Uboom L instead.
