In addition to the rubber balls, there’s a nice physical interface on the side for adjusting volume and pairing multiple Mix speakers together if you have multiple on hand (I was only sent the single mono speaker). Setup involves installing the Soundboks app, pairing to the speaker via Bluetooth on your phone, and picking 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 audio. Everything reminds me very much of the Peavey PA system I have in my music rehearsal space. The top of the speaker features a built-in carrying handle and a place for a strap (an accessory you have to buy aftermarket, or you can fasten it with any strap you have that fits through the hole). There are also top-hat mounts for the speakers to slide onto traditional PA pole stands, if you wanted to use them in that way at a party or event.
The grill is replaceable, as is the massive internal battery, which means that these things are pretty much indestructible as long as the amp and speakers themselves still work—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 testing period, and the thing just 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 about eight hours at max volume (which is very good for the category). If you need to bring some walk-out music to your kid’s all-day Little League tournament, this a great way to go.
Big Sound
Soundboks calls this speaker midsize, but at 21.4 pounds and the size of a medium-size cooler, I’d still call it a large speaker. That said, the size doesn’t make it any less portable than competitors from JBL and others; you still need a car or cargo ebike to take one of these with you, so what’s a couple inches here or there? The fact that this is a rectangle actually makes it easier to strap down than many others, especially with the holes for the strap and the built-in handle to tie down through.
