Short answer: the Ultimate Ears Miniroll for better sound quality, the Boat Stone 190 for the lower price. The Ultimate Ears Miniroll ranks #12 of 50 small speakers, rated 3.9/5, at $49.99. The Boat Stone 190 ranks #34, rated 2.9/5, at $9, $40.99 cheaper.
The Ultimate Ears Miniroll is the better-sounding, longer-running pick. Good clarity and detail in the mids and highs, with a warmer balance than most speakers its size. It is rated for 12 hours of battery against 6.5 for the Boat Stone 190. It links with other speakers (PartyUp/Auracast, Miniroll-only), which the Boat Stone 190 cannot. The catch: Bass does not reach as deep as the best-rated speakers.
The Boat Stone 190 is the lighter option. Ultra-lightweight 0.4 lbs (185 g) design with IPX7 waterproof protection. At 0.4 lbs (185 g) it weighs noticeably less than the Ultimate Ears Miniroll at 0.6 lbs (279 g). It keeps a wired aux input, which the Ultimate Ears Miniroll lacks. Watch for: Minimal low bass extension below 95Hz; highs are rolled off at higher volume.
Buy the Ultimate Ears Miniroll when sound quality outweighs the price for you, and the Boat Stone 190 when the price outweighs sound quality instead.
