Short answer: the Soundcore Boom Go 3i if sound quality matters most, the Onn Small Rugged Speaker if price matters most. The Soundcore Boom Go 3i ranks #2 of 62 small speakers, rated 4.4/5, at $79.99. The Onn Small Rugged Speaker ranks #35, rated 3.1/5, at $14.88, $65.11 cheaper.
The Soundcore Boom Go 3i is the better-sounding, longer-running pick. A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. It is rated for 24 hours of battery against 10 for the Onn Small Rugged Speaker. It has an adjustable EQ, which the Onn Small Rugged Speaker lacks. The catch: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic.
The Onn Small Rugged Speaker is the lighter option. A very cheap, tough waterproof mini speaker with USB-C charging, an aux input, and a speakerphone mic. At 0.6 lbs (286 g) it weighs noticeably less than the Soundcore Boom Go 3i at 0.8 lbs (380 g). It keeps a wired aux input, which the Soundcore Boom Go 3i lacks. The catch: 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 Soundcore Boom Go 3i if sound quality is the priority over the price, or the Onn Small Rugged Speaker if the price is the priority over sound quality.
