Looking for an excellent Bluetooth speaker that won't overwhelm your wallet? Right now, you can get Soundcore Boom 3I for just $75 on Amazon and Walmart -- that's $65 off its regular cost. We've been tracking the price of this product, and this is the lowest we've seen. The rugged and powerful Anker Soundcore Boom 3I is the updated version of the Boom 2, which is our top pick for the best value speaker of 2026.

It's no surprise that this is a limited-time deal, so grab one before the stock runs out. You'll also have to make a tough decision of which color to pick (you should definitely choose the green one).

This speaker has a stacked set of features that make it an incredible value for just $75. It's equipped with a 40W subwoofer for rich, powerful lows and a 10W tweeter for crisp, piercing highs, and it has an impressive maximum volume of 96dB.

It's also perfect for summer adventures with a seriously durable design. It's fully waterproof -- including protection against saltwater -- and is designed to float so you don't have to worry about taking it out on a boat. You can also keep the party going all day or night with a 16-hour battery life, and it has built-in LED lighting to help set the mood. It weighs just under 2 pounds and has a detachable shoulder strap for easy transport.

CNET's audio expert, David Carnoy, said the Boom 3I "sounds great and works while floating in water," also noting that, "the Soundcore Boom 3I gives you what you want from a portable Bluetooth speaker from a sound perspective. By that I mean it plays loud for its size -- it weighs about 1.8 pounds and measures 8.3 by 3.1 by 3.3 inches -- plus it puts out a reasonable amount of bass and has fairly respectable clarity."

Note that this is a limited-time deal, so we can't vouch for how long it's going to last. At least you don't have to enter any codes or clip any coupons, and your new speaker could be with you as soon as tomorrow.

Why this deal matters

Claiming multiple spots on our list of the best Bluetooth speakers of 2026, Anker's Soundcore speakers offer a tremendous value thanks to their solid sound, affordable price and rugged design.

The Soundcore Boom 3I is perfect for camping trips, beach days and just about any other summer adventures. It's already a decent value at full price, so a chance to pick it up for $65 off is a deal you won't want to miss.
