Short answer: the JBL Go 4 for better sound quality, the Onn Small Rugged Speaker for the lower price. The JBL Go 4 ranks #30 of 62 small speakers, rated 3.2/5, at $42.99. The Onn Small Rugged Speaker ranks #35, rated 3.1/5, at $14.88, $28.11 cheaper.
The JBL Go 4 is the lighter option. A pocket sized waterproof mini speaker with a loop for hanging and app EQ. At 0.4 lbs (190 g) it weighs noticeably less than the Onn Small Rugged Speaker at 0.6 lbs (286 g). It has an adjustable EQ, which the Onn Small Rugged Speaker lacks. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
The Onn Small Rugged Speaker is the deeper-bass pick. A very cheap, tough waterproof mini speaker with USB-C charging, an aux input, and a speakerphone mic. Its bass reaches about 66Hz before falling 10dB, against 82Hz for the JBL Go 4. It keeps a wired aux input, which the JBL Go 4 lacks. The tradeoff: 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 JBL Go 4 if sound quality is the priority over the price, or the Onn Small Rugged Speaker if the price is the priority over sound quality.
