Soundboks Mix Review: A Great Party Speaker

In addition to the rubber balls, there’s a nice physical interface on the side for adjusting the volume and connecting multiple Mix speakers together if you have multiple on hand (I was only sent the single mono speaker). Setup involves installing the Sound box appconnect to the speaker via Bluetooth on your phone, and select whatever you want to play. It’s all quick and painless, especially for my first time pairing with a Samsung Galaxy S24 Ultra.

Otherwise, it’s all very pro-sounding. Everything reminds me a lot of the Peavey PA system I have in my music practice space. The top of the speaker has a built-in carrying handle and a place for a strap (an aftermarket accessory, or you can attach it with any strap you have that fits through the hole). There are also hat mounts for the speakers to slide onto traditional PA pole stands, if you want to use them that way at a party or event.

The grill is replaceable, as is the massive internal battery, meaning these things are pretty much indestructible as long as the amp and speakers themselves are still working – the battery is the weak point of most portable speakers in 2026.

I bounced it around my yard, dropped it off my patio, and generally beat the crap out of it during my two-week test period, and the thing only needed a little wipe down and a charge when it ran out of juice. The claimed 40 hours of battery at reasonable volume is accurate, but you’ll get around eight hours at maximum volume (which is pretty good for the category). If you need to bring some walkout music to your kid’s all-day Little League tournament, this is a great way to go.

Soundboks calls this speaker mid-sized, but at 21.4 pounds and the size of a medium coolerI would still call it a large speaker. That said, the size doesn’t matter less portable as competitors of JBL and others; you still need a car or cargo e-bike to take one of these with you, so what’s a few inches here or there? The fact that it is a rectangle actually makes it easier to tie than many others, especially with the holes for the strap and the built-in handle for tying through.
