AI Verdict
A rugged, floating $30 speaker that trades heavy bass for an impressive 20-hour battery life and a customizable EQ.
At under $40, this speaker over-delivers for casual outdoor and shower use with its 20-hour battery and floating IP67 design. The 5W output and clear mid-range make it perfect for podcasts. The lack of sub-bass means it won't power a real party.
If you need deep bass or plan to watch videos without audio lag, step up to the Soundcore Motion 300 or a speaker with an aux input.

Pros
- 20-hour battery life outlasts the JBL Go 4's 7-hour rating
- IP67 waterproof rating and naturally floats in pools
- Companion app includes a 9-band customizable EQ
- Supports True Wireless Stereo pairing to link two units
Cons
- Silicone rubber feet peel off easily after a few months
- Half-second Bluetooth audio latency ruins video lip-syncing
- Closed built-in loop requires a separate carabiner to clip to bags
- 5W mono driver produces virtually no sub-bass
Dimension Scores
The 9-band EQ fixes harsh treble, but the 5W driver struggles with sibilance at max volume.
The tiny mono driver physically cannot reproduce low-end thump for bass-heavy tracks.
TWS pairing works flawlessly, but the high video latency and lack of a 3.5mm aux jack limit its versatility.
The 9.3-ounce waterproof body is incredibly easy to pack, though the flimsy rubber feet drag down long-term durability.
Best For
- Listening to podcasts in the shower using the built-in hanging loop
- Floating in the pool or taking to the beach thanks to the IP67 rating
- Budget stereo setups by pairing two units via TWS
Not Recommended For
- Watching YouTube or movies on a laptop due to audio lag
- Listening to bass-heavy EDM or hip-hop tracks
- Clipping directly to thick backpack straps out of the box
Watch Out For
- The four silicone rubber feet on the bottom wear away or peel off entirely within a few months of use.
- Bluetooth latency creates a noticeable half-second audio delay, making it frustrating to use for watching movies or YouTube.
- The built-in loop is completely closed—you must buy a separate carabiner to actually clip it to a backpack or belt.
- There is no built-in microphone, meaning you cannot take phone calls or use voice assistants through the speaker.

What Buyers Say
The most surprising thing about this $30 speaker is the inclusion of a 9-band EQ via the Soundcore app, a feature usually reserved for much pricier models. Battery tests confirm the 20-hour rating, easily outlasting the JBL Go 4's 7-hour limit. The physical design has a glaring flaw: the four silicone feet on the bottom are notorious for peeling off after just a few months. Video watchers frequently complain about a half-second audio delay that ruins lip-syncing.
“For 30 bucks it's a no brainer for the shower, just don't expect it to shake the room and be prepared to lose the little rubber feet on the bottom.”
Common Praise
- Battery easily lasts weeks on a single charge at moderate volumes
- Survives being completely dropped in the pool and floats to the top
- App includes a 9-band custom EQ to tune out harsh treble
- Vocals and podcasts sound incredibly clear for a 5W driver
Common Complaints
- Silicone rubber feet wear away or fall off entirely after a few months
- Noticeable audio lag makes watching YouTube or movies frustrating
- Closed loop design requires buying a separate carabiner to clip it to things
- Zero low-end bass for hip-hop or EDM tracks
Ownership Tips
- The rubber feet on the bottom will likely peel off or wear down within the first 3-4 months of use.
- You will notice a half-second audio delay if you try to use it as a laptop speaker for movies.
- The fabric mesh holds up well to dirt, but the closed loop means you will definitely want to buy a cheap carabiner.
Frequently Asked Questions
Does it have a microphone for phone calls?
No, there is no built-in mic. You cannot use it as a speakerphone or access voice assistants.
Can I pair two of these together?
Yes, it supports True Wireless Stereo (TWS) pairing. You can link two Select 4 Go speakers for dedicated left and right channel audio.
Does the loop open so I can clip it to my bag?
No, the loop is a closed strap. You need to attach a separate carabiner if you want to clip it to a backpack or belt loop.
Is there audio lag when watching videos?
Yes, buyers report a noticeable half-second audio delay when watching YouTube or movies via Bluetooth.
Does it actually float?
Yes. The IP67 rating allows it to survive submersion up to 3.3 feet, and the lightweight 9.3-ounce chassis naturally floats on the water's surface.
Buying Guide
When buying an ultra-portable budget speaker, you trade heavy bass for extreme portability and battery life. A 5W speaker like this is meant for personal listening in a shower or small room, not for hosting a backyard BBQ. Pay attention to the physical attachment points. A closed loop means you can hang it on a hook, but you cannot clip it to a bag without buying extra hardware.
IP67 Rating
The '6' means it is completely dustproof for the beach, and the '7' means it survives being dropped in 3.3 feet of water for 30 minutes.
5W Output
Think of this as the engine size. 5 watts is enough to hear a podcast over shower water, but it will not vibrate your desk with bass.
True Wireless Stereo (TWS)
This lets you buy two identical speakers and link them wirelessly so one plays the left audio channel and the other plays the right.
Alternatives
If you need a built-in clip for your backpack, look for a speaker with an integrated carabiner design. If you want to watch videos without lip-sync issues, seek out a speaker with an aux input.
