Minirig 4 vs Ultimate Ears WONDERBOOM 4

The Ultimate Ears WONDERBOOM 4 is more versatile than the Minirig 4, though less customizable. The Ultimate Ears speaker's battery lasts longer with a tougher IP67 rating, meaning it's suited for adventures. It sounds nearly the same at every listening angle with better dynamics performance at max volume, too. Its controls are clearly laid out and you can pair a second compatible speaker over Bluetooth. However, the Minirig offers both wired and Bluetooth connections with an app that lets you adjust the bass and treble. Despite being smaller, it also gets a bit louder. You can also use it as a power bank to recharge other devices. However, its IPX4 rating won't ward off damage beyond a few raindrops.
