Short answer: the Tribit Stormbox Micro 2. It ranks #1 of 62 small speakers by sound quality, rated 4.5/5, at $35.39. The Onn Small Rugged Speaker ranks #35, rated 3.1/5, at $14.88, $20.51 cheaper, which does not close the gap in sound quality.
The Tribit Stormbox Micro 2 is the better-sounding pick. An excellent sounding small speaker, with surprisingly deep bass for its size and a strap that holds it on a bike or backpack. It has an adjustable EQ, which the Onn Small Rugged Speaker lacks. The catch: Finicky phone charging, which doesn’t usually work.
What the Onn Small Rugged Speaker does well: 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 Tribit Stormbox Micro 2 lacks. It links with other speakers (Party Sync Mode), which the Tribit Stormbox Micro 2 cannot. 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.
Buy the Tribit Stormbox Micro 2. It is rated higher for sound quality, and saving $20.51 with the Onn Small Rugged Speaker does not make up for the sound-quality gap.
