Short answer: the Ultimate Ears Miniroll for better sound quality, the Onn Small Rugged Speaker for the lower price. The Ultimate Ears Miniroll ranks #12 of 62 small speakers, rated 3.9/5, at $49.99. The Onn Small Rugged Speaker ranks #35, rated 3.1/5, at $14.88, $35.11 cheaper.
Why pick the Onn Small Rugged Speaker: A very cheap, tough waterproof mini speaker with USB-C charging, an aux input, and a speakerphone mic. It keeps a wired aux input, which the Ultimate Ears Miniroll lacks. Watch for: Its 1.5-inch driver cannot create meaningful deep bass (about 66Hz at -10dB) or the clarity and scale of better small speakers.
The Ultimate Ears Miniroll is the better-sounding choice. A waterproof strap on mini speaker with clear mids and highs, a warm balance, and a long battery for its size. The catch: Bass does not reach as deep as the best-rated speakers.
Buy the Onn Small Rugged Speaker if the price is the priority over sound quality, or the Ultimate Ears Miniroll if sound quality is the priority over the price.
