In my review of the flagship Soundboks 4, I noted I was hesitant to blast it at its max 126 dBs while outdoors (mainly for fear of noise complaints, as I was in a park next to many residential homes)—and while I’m glad I did anyways, not everyone needs this much power. Enter the more affordable, more compact younger-sibling speaker.

The Soundboks Go is much more portable and almost as loud, with the same 40 hours of battery life. As you can read in my review of the Soundboks Go, you’ll get an impressive volume of 121 decibels in a small 20-pound speaker. It’s also rugged, with a splash and dust-proof IP65 rating. I took it to my local soccer field and was able to blast music for 22 players to enjoy throughout the rain, even taking a couple of tumbles from loose soccer balls.

The speaker is made for those who want an easy portable speaker that you can carry with a single hand but deals some serious damage while still sounding great. While it may lack many party tricks and features, it does the simple things extremely well.

Looking for something else? Retailers like Walmart, Best Buy, and Home Depot have Prime Day competition sales that are especially useful if you don’t have Amazon Prime.

• Walmart’s Prime Day competition sale begins at midnight on July 8 and will include deals up to 50% off. It’s an especially good option if you have Walmart+. 

• Best Buy’s Prime Day competition sale, “Black Friday in July,” runs through Sunday, July 13 and has some of the best tech sales online. It’s an especially good option if you’re a My Best Buy “Plus” or “Total” member.

• Home Depot extended its 4th of July sale through at least July 9, competing with some amazing deals of its own. It’s an especially good option if you’re looking for power tools, appliances, or outdoor equipment.
