Short answer: the Minirig Mini 2 on measured sound quality, the Onn Small Rugged Speaker on price. The Minirig Mini 2 ranks #3 of 63 small speakers, rated 4.4/5, at $100. The Onn Small Rugged Speaker ranks #35, rated 3.1/5, at $14.88, $85.12 cheaper.
The Minirig Mini 2 is the better-sounding, deeper-bass option. A tiny, very neutral speaker with much deeper bass than most its size, a long battery, and an optional add on subwoofer. Its bass reaches about 58Hz before falling 10dB, against 66Hz for the Onn Small Rugged Speaker. It supports aptX Bluetooth, which the Onn Small Rugged Speaker lacks. It has an adjustable EQ, which the Onn Small Rugged Speaker lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
The Onn Small Rugged Speaker is the tougher pick. A very cheap, tough waterproof mini speaker with USB-C charging, an aux input, and a speakerphone mic. It is rated IPX7 against Splash resistant for the Minirig Mini 2. It links with other speakers (Party Sync Mode), which the Minirig Mini 2 cannot. 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.
