Most cheap Bluetooth speakers ask you to accept a compromise you can feel within a week. The battery fades, the plastic creaks, and the first splash at the pool ends the relationship for good. Spend more and you fix those problems, or so the pricing tells you.
Soundcore Select 4 Go Bluetooth Shower Speaker by Anker
Price: $22.99
Where to Buy: Amazon
The Soundcore Select 4 Go argues the opposite for $22.99. Anker’s palm-sized speaker carries an IP67 rating, floats, and claims 20 hours on a charge, the kind of spec sheet that usually costs three times as much. The real question isn’t whether it’s cheap. It’s whether a speaker this small earns a permanent spot in your bag.
Why the Durability Spec Does the Selling
IP67 is the number that separates this from the drugstore-shelf speakers it competes with. The rating means full dust sealing plus submersion in up to 3.3 feet of water for 30 minutes, so a drop in the pool or a sink full of suds is a non-event. Anker also builds it to float, which turns a dropped speaker into a minor annoyance instead of a lost gadget.
The body backs up the claim. It’s a PC and ABS shell that weighs 9.3 ounces and measures roughly 3.2 by 4.7 by 1.9 inches, small enough to close your hand around. A built-in loop clips it to a shower caddy, a backpack strap, or a set of bike handlebars without a separate mount.
That combination is the whole pitch. You can leave it in the bathroom, toss it in a beach bag, or hang it in the garden, and none of those places threaten it. Amazon shoppers rate it 4.7 out of 5 across more than 12,000 reviews, it holds an Amazon’s Choice badge in its category, and it lines up with the budget picks in our 2026 Bluetooth speaker buying guide.
Twenty Hours on a Charge, Then a Quick USB-C Top-Up
Battery life is where budget speakers usually cut the deepest, and it’s where the Select 4 Go spends its money instead. Anker rates it at 20 hours, enough to cover a week of showers or a full day at the lake on a single charge. Real playtime drops as you push the volume, so treat 20 hours as a ceiling rather than a promise.
Charging runs through a USB-C port behind a sealed flap, and a full top-up takes about 4.5 hours from the 2.4 Ah cell. Anker includes a short USB-A to USB-C cable but no wall plug, so you’ll pull power from a charger or laptop you already own.
What the 5W Driver Can and Can’t Do
The price sets modest expectations here, and the hardware explains why. A single 45mm dynamic driver pushing 5 watts moves the Select 4 Go’s sound, and physics caps what that hardware can do. You’ll get clear vocals and enough volume to fill a bathroom or a small patio, not the chest-thumping low end of a speaker four times the size.
Bluetooth 5.4 handles the connection out to about 30 meters, more range than you’ll use indoors and plenty for a backyard. Pairing takes a single button, and 5.4 is a newer radio than the 5.0 and 5.3 versions common on speakers this cheap.
The Soundcore app is the lever that changes the character of the sound. It adds adjustable EQ, so you can lift the bass for music or flatten it for podcasts instead of living with one fixed tuning. For a speaker at this price, having any EQ control at all is a real step up.
If one unit isn’t loud enough, True Wireless Stereo pairs two of them into a left and right set. Two Select 4 Go speakers still cost less than a single mid-tier portable, which is the quiet argument Anker is making against stepping up a tier.
Who Should Grab One, and Who Should Skip It
This is a grab-and-go speaker, and it’s happiest in the roles that ruin pricier gear. Buy it for the shower, the pool, the campsite, the garden, or the workbench, anywhere water, dust, or a drop would make you nervous with a $100 speaker.
It also makes a smart gift and a low-risk first speaker for a kid or a dorm, since soaking or losing it costs you $23 rather than a weekend’s budget. The 20-hour battery means it rarely dies mid-use, which matters more day to day than a spec war over watts.
Skip it if you want room-filling bass for a party, or if you already own a larger portable that covers outdoor duty. A single 5W driver won’t anchor a backyard gathering. For that job, size up to one of the waterproof speakers we picked for summer.
What’s Good and What Isn’t
The IP67 sealing shrugs off dust and full submersion, and the fact that it floats means dropping it is never a crisis.
The 20-hour battery outlasts most speakers at this price, and it charges over USB-C with the cable already in the box.
The Soundcore app throws in real EQ control, which you don’t usually get this cheap, and TWS pairing lets two units team up for wider stereo.
The tradeoffs are narrower but real. A single 5W driver limits how much low-end bass you’ll ever get out of it, and Anker doesn’t bundle a wall charger, so you’ll need to supply your own.
The Bottom Line
If you’ve wanted a speaker you can stop worrying about, the Select 4 Go is worth the $22.99. It trades big bass for durability, battery life, and a price low enough to stop worrying about, and for shower, pool, and travel use, that’s the right trade.

Want it as your only speaker for parties and bass-heavy nights? Look at a bigger model. Want one you can hang in the shower today and forget about for a week? This is the one to grab, and a second one in stereo still undercuts the competition.
