Anker Soundcore Mini 3 Bluetooth Speaker Review
Pocket-sized waterproof speaker with surprisingly punchy bass for backyard hangs and shower sing-alongs.
A waterproof Bluetooth speaker that fits in a cup holder, survives a poolside splash, and pumps out bass no can-sized speaker has any business making. For under $45, it's the easy pick.
What the Soundcore Mini 3 actually is
This is Anker's pocket-sized portable Bluetooth speaker, roughly the size of a soda can and built to get wet. It carries an IP67 rating, which means it shrugs off dust and survives a brief dunk in shallow water. The brief part matters. It's splash-proof and drop-in-the-pool-proof, not a submarine.
Anker positions it as a grab-and-go speaker for showers, backpacks, picnic tables, and kitchen counters. It's not trying to fill a house party. It's trying to follow you around, and at this size it does that job better than most.
How it sounds day to day
The headline feature is bass, and owner consensus backs it up: for something this small, the low end is genuinely impressive. Anker uses what it calls BassUp tech to squeeze more thump out of the drivers, and on tracks with a steady beat it delivers. Vocals and mids come through clean at normal listening levels.
Push it to max volume and the limits show up. Treble can get a touch harsh and the bass loses composure, which is true of basically every speaker in this size class. For a shower, a kitchen, a backyard table, or a hotel room, it's more than loud enough. As the only speaker for a 30-person cookout, it'll struggle. Know which job you're hiring it for.
Battery, app, and the small stuff
Anker rates it around 15 hours, and like most speakers that figure assumes moderate volume. Crank it loud and lean on the bass and you'll see less. Still, you can run it most of a day on a charge, and it tops up over USB-C, which is the right port to have in 2025.
The Soundcore app adds a custom EQ and a few sound presets, so you can tame the treble or boost mids if the default tuning isn't your taste. It's a nice extra, not a requirement. You can pair two units for stereo if you buy a second one down the line.
Who should buy it, and who shouldn't
Buy it if you want a cheap, durable speaker that travels well and sounds better than it looks. It's a smart pick for showers, dorm rooms, beach bags, and bike rides. Anyone shopping the under-$50 aisle who wants real bass without a JBL-sized price tag should put this near the top of the list.
Skip it if you need room-filling volume or party-level output. Step up to a JBL Flip 6 or the larger Soundcore Motion line if you want more punch and headroom, though you'll pay more than double. And if you already own a solid mid-size speaker, the Mini 3 is a second speaker, not an upgrade.
The verdict
The Soundcore Mini 3 is one of the easiest recommendations in the budget speaker category. It's small, tough, waterproof, and surprisingly bassy for the money. You're not getting big-room sound, and you shouldn't expect it. For a portable everyday speaker in the $35 to $45 range, it nails the brief and then some.

- How long does the battery last?
- Anker rates it around 15 hours at moderate volume. Expect noticeably less if you play it loud with the BassUp feature on. It charges over USB-C.
