Volume Up, Prices Down: Early Prime Big Deal Days Sales on Speakers and Soundbars

September 29, 2025

Amazon’s Prime Big Deal Days sale is happening Oct. 7 and 8, and if you’re like me, having great sound wherever you go really makes all the difference. From drives through the countryside to lazy pool days to even hair-wash day, there’s always a background score to my life, thanks to my speakers. Portable speakers today don’t just get loud; they’re waterproof, dust-proof, and tough enough to toss anywhere. And with brands like JBL, Anker, and Beats already marked down, these early discounted speakers are basically begging me to upgrade. Keep your eyes (and ears) on this space for updates leading to big sale days.

Ultimate Ears Speaker Deal

The Wonderboom 4 is a great combo of tiny and mighty. It offers 360-degree sound with surprising bass punch for such a small device. It’s fully waterproof and dust-proof, and it even floats if it falls in the pool or lake. You’ll get around 13 hours of playtime, which means it keeps going as long as you do. The early 12% discount brings it down to $88 right now from its original $100 price, making it a great reason to toss out those old speakers. Note, however, this deal might not last long.

The Ultimate Ears Boom 4 is the kind of speaker you can drag to the pool, the beach, or a camping trip without stressing. It’s fully waterproof, floats even if it takes a dive, and pushes out 360-degree sound that really feels bigger than its size. Its battery life runs up to 15 hours, and the 147-foot Bluetooth range means you don’t have to keep your phone glued to it either. Right now, you can get it at $129.99, down 13% from its usual $150 price. It’s a sturdy, fun pick for anyone who wants music that actually follows them outdoors.

Anker Soundcore Speaker Deal

This speaker can really stand up to the elements; the Boom 3i is literally built for it. It’s waterproof, dust-proof, and saltwater-resistant, so it’s ready for fishing trips, camping, or just a day at the beach. Its BassUp technology adds some real oomph to all your jams, and 16 hours of battery life keeps the party going. Right now, it’s priced at $99.99, which is a 29% discount on its original $140 price. This really is a great pick for those wanting tough gear and great sound.

The Anker Soundcore 2 has been around for years, and there’s a reason people keep buying it. It’s small enough to toss in a bag, but its stereo sound and BassUp tech give it more punch than you’d expect for this size. You get 24 hours of battery life, IPX7 waterproofing for poolside or travel, and the option to pair 2 devices together for even better sound. At $29.99, down 33% from its actual $45, the Soundcore 2 is still one of the easiest speaker buys you can make.

We love this one, and here is what our experts have to say about Anker products.

Beats Speaker Deal

The Beats Pill combines serious sound with a look that fits everywhere. It puts out clear, super loud music, lasts up to 24 hours on a single charge, and is water-resistant enough to handle occasional splashes and spills. It’s compatible with both Apple and Android, making it a good go-to whether you’re traveling or just want quality sound at home. PCMag’s audio expert Tim Gideon rated this one “Excellent” in his review and noted how it really stands out for everyday use. At 14% off for early Prime Day, it’s going for $129, down from its original $150 price tag.

Bose Speaker Deal

The Bose SoundLink Flex (2nd Gen) is a compact portable speaker that still manages to deliver super hi-fi audio. It’s fully waterproof and dustproof, and the 12-hour battery life keeps it running through most of the day. Its design is tough but still feels sleek enough to carry anywhere. Our expert, Tim Gideon, rated it “Excellent” in his 2021 review, highlighting how Bose manages to make small speakers sound much bigger than they look. At $129, down almost 13% from its usual $150, it’s an easy grab if you want premium yet portable sound.
