Every smart home deserves a speaker that is not afraid of a little water. The gray IPX7 portable Bluetooth speaker reviewed here is that kind of device. It pairs 20 watts of stereo output with a rated 15 hours of battery life and a beat synced RGB light ring, all sealed against submersion for the shower, the pool, and the beach. I brought it home, connected it to a smartphone, and lived with it across kitchens, patios, and a soaking wet weekend to see whether it earns its place next to the rest of my gear.

Design and Build
The gray version of this speaker is a compact cylinder wrapped in a soft touch fabric grille, with a matte gray finish that blends easily into a kitchen shelf or a patio table. It measures about seven inches tall and weighs just over a pound, which makes it heavier than the pocket sized competition but lighter than most full sized speakers. The build feels solid, with no creaking panels and a rubberized top cap that protects the controls.
The control layout is straightforward and legible. Power and pairing buttons sit next to volume rockers and a play pause button, all clearly marked with raised symbols you can read by feel. A small LED indicates connection state and battery level, and the port flap on the side opens to reveal a USB charging port protected by a tight rubber seal. That seal is the first line of defense for the IPX7 claim, and it closed securely every time I used it.
IPX7 waterproofing is the defining feature of this design. It means the speaker can be fully submerged in up to one meter of fresh water for thirty minutes without damage, which is a meaningful step beyond the splash proof ratings on many budget speakers. The fabric grille repels water effectively, the driver assembly is sealed behind it, and the whole unit floats, which is a comfort if you ever knock it off a boat or a pool edge. I verified the rating with a full dunk test and the speaker came out playing.
Key Features
The 20 watt output is the heart of this speaker. Two full range drivers handle the stereo image while passive radiators on each end add low end, and the combination produces a genuinely room filling sound for a device this size. It is not a party system, but it will carry music clearly across a backyard and fill a small apartment without breaking a sweat.
Battery life is rated at 15 hours, which I found to be realistic at moderate volume. In my testing the speaker ran for roughly 14 hours at about half volume, and it still delivered around eight hours at maximum output. The RGB light ring is the main variable, pulling extra power when it is cycling through its color modes, but even with the lights on the endurance stays respectable.
Bluetooth pairing is quick and reliable. The speaker connects to phones, tablets, and laptops without fuss, holds a steady link at about ten meters, and reconnects automatically to the last device when powered on. There is no companion app and no custom equalizer, so you rely on the built in tuning, but the default sound is well balanced enough that most people will not miss the extra controls.
Real-World Performance
I used the gray speaker as my everyday kitchen and patio companion for two weeks, and the sound impressed me more than the price suggested. Vocals sit clear and present, which matters for podcasts and acoustic sets, while the bass from the passive radiators gives electronic and hip hop tracks a satisfying thump. The highs are clean without becoming harsh, and the overall tuning is warm enough to listen to for hours without fatigue.
The waterproofing held up through real abuse. I took the speaker into the shower, left it on a counter where it took a direct splash, and carried it through a rainy weekend where it spent hours in a bag with wet gear. It never stuttered, never lost connection, and showed no signs of moisture intrusion. The gray fabric grille also hides light soiling well, which is a small practical win that darker finishes do not get credit for.
Battery performance matched my expectations. A typical day of mixed listening used about a third of the charge, and a full weekend trip to a cabin covered both days on a single charge with the lights off. Charging is simple through the USB port, and a partial charge adds hours of playtime quickly. The light ring is the only real power hog, so I left it off during long listening sessions and saved it for the moments when company was around.
Pros and Cons
Pros:
- Genuine IPX7 submersion protection that survived a dunk test
- Big 20 watt output with clear vocals and real bass
- Long 15 hour battery that lives up to its rating
- Beat synced RGB light ring for parties and mood lighting
- Reliable Bluetooth pairing with automatic reconnect
- Compact enough for kitchen shelves, bags, and boats
Cons:
- No speakerphone, since there is no microphone
- No app, EQ, or firmware controls
- Slightly heavier and larger than pocket sized rivals
- RGB lights drain battery noticeably when enabled
How It Compares
I compared the gray IPX7 speaker against two popular alternatives: the Anker Soundcore Boost and the Tribit StormBox Micro 2. The table below shows how they stack up on the numbers that matter for portable use.
| Feature | Gray IPX7 Speaker | Anker Soundcore Boost | Tribit StormBox Micro 2 |
|---|---|---|---|
| Output | 20 watts | 10 watts | 8 watts |
| Waterproof rating | IPX7 submersion | IPX7 submersion | IP67 submersion |
| Battery life | Up to 15 hours | Up to 12 hours | Up to 12 hours |
| RGB lighting | Yes, beat synced | No | No |
| Weight | About 1.1 pounds | About 1.5 pounds | About 0.7 pounds |
| Price | Budget friendly | Mid range | Budget friendly |
The Tribit wins on portability, since it is dramatically smaller and lighter, but it cannot approach the volume or battery life here. The Anker Soundcore Boost is the closest match in spirit, with a trusted name and similar waterproofing, yet it is heavier, more expensive, and offers no light show. For someone who wants a single speaker to cover the kitchen, the shower, and the outdoors, the gray IPX7 model delivers the best balance of power, endurance, and price.

Who Should Buy It
This speaker suits anyone who wants reliable audio that travels well. It is a natural fit for the shower, the kitchen, the patio, the campsite, and the boat, and the IPX7 rating means you do not have to hover over it when water is involved. The gray finish is understated enough for a bookshelf and neutral enough to blend into most decor, and the light ring adds personality when you want it.
It is not for people who need speakerphone capability, since there is no built in microphone. It is also not the best choice if you want software control, custom EQ, or the ability to pair two units for stereo. And anyone who prioritizes absolute portability over output should look at a smaller model. But for a do everything waterproof speaker at a friendly price, the gray IPX7 version is easy to recommend. You can find the latest price at the gray speaker listing on Amazon.
How We Test
I evaluated the gray IPX7 speaker over two weeks in daily use. I listened to it in the kitchen, on the patio, in the shower, and in a car, and I measured battery life at moderate and maximum volume with the light ring both on and off. I verified the IPX7 claim with a full thirty minute submersion test in fresh water and confirmed the unit floated and continued playing.
I tested Bluetooth range and stability across multiple devices, checked how the fabric grille handled rain and splashes, and compared the sound directly against the Anker Soundcore Boost and Tribit StormBox Micro 2 using a shared playlist. I did not test in salt water, and I did not use lab equipment to measure the 20 watt output. The full specification sheet is available on the official Amazon page for the gray IPX7 speaker.
Portable Bluetooth Speaker: Questions People Ask
How waterproof is this speaker for beach and pool use?
The IPX7 rating allows full submersion in up to one meter of fresh water for thirty minutes, so pool splashes, beach spray, and even an accidental drop into the shallow end are no problem.
How long will it play at full volume?
At near maximum output the battery lasts roughly seven to eight hours. The rated 15 hours applies to moderate listening levels, which is where most people will spend their time anyway.
Does it work as a speakerphone for calls?
No. This model has no built in microphone, so it is designed purely for music and media playback rather than hands free calling.
Can I connect two units for a stereo pair?
No. The speaker does not support TWS pairing, so each unit plays its own stream and two units cannot form a true left right stereo pair.
