Our Verdict
Minirig 4
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, and its tougher IP67 rating makes it suited for adventures. 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 fair bit louder than the Ultimate Ears. You can also use it as a power bank to recharge other devices. However, its IPX4 rating won't ward off damage from more than a few raindrops.

Hi there,
Thank you for pointing this out. We will take a look at both reviews and make sure the recordings were done correctly.
why does the minig’s binaural recording sound like its been boosted a lot? there is loud hiss at the start before the speaker starts playing. has the gain not been set correctly? any other speaker sounds a lot quieter and less hiss. both are tested with the same methodology, but something sounds quite off, and not because of the speaker itself.
