Bath Time Sounds This Good?! True Stereo with Two KREAFUNK aJAZZ+ Speakers Is Amazing

I’ve tried lots of waterproof Bluetooth speakers for listening to music in the bath. But KREAFUNK is in a league of its own.

What I love: it doesn’t overdo the bass. Lots of Bluetooth speakers these days pump out surprising bass from tiny bodies, but the aJAZZ+ doesn’t push it more than needed. So violins, pianos, and horns don’t get buried — it’s perfect for classical and jazz.

It’s also rated IPX5, and pairing two gives you true left/right stereo.

Bath-friendly, great-looking as decor, and lets you enjoy classical and jazz in proper stereo. I’d never found a speaker like this before.

When I brought two into the bathroom, my daily bath went from “a place to wash” to “a place I want to listen to music.”

## Stereo in the bath makes a huge difference

Put one on each side for stereo, and the sound opens up — it feels like the whole bathroom fills with music.

Classical is especially great. It doesn’t build impact by booming bass, so strings, piano, and horns are really easy to listen to. Add the bathroom’s natural echo, and the sound gets this lovely spaciousness.

Jazz too — the bass doesn’t jump out more than it should, so piano, horns, and vocals all come through in balance.

“Big bass” doesn’t mean “good sound”

Lots of portable Bluetooth speakers these days sell themselves on bass impact. That’s fun in its own way, but with classical or jazz, it can feel like “that’s a bit too much bass.”

The aJAZZ+ is the opposite. The bass is there — but it doesn’t hog the spotlight, so the overall balance holds.

That really matters in an echoey bathroom. It’s already a space where sound bounces around, so boosted bass can get pretty loud and boomy. The aJAZZ+ stayed easy on the ears even over long listening sessions.

IPX5 means you can bring this sound into the bath

It’s IPX5, so it can’t be submerged, but the maker itself designs it with bathroom use in mind.

There are tons of great-sounding speakers. But sound good enough to truly enjoy classical and jazz, and casual enough to take somewhere wet?

That combo is why I felt I’d never seen a speaker like this before.

Singing with my kid became even more fun

Put on a favorite song and sing together. That alone turns bath time into a little playtime.

With two speakers, the sound fills the whole bathroom without cranking the volume, which is nice too.

I think the most interesting gadgets aren’t just about impressive specs — they’re the ones that make time with your family a little more fun.

Long battery life means I barely think about charging

Considering how long a bath takes, you don’t need to charge it every day, and in practice I barely think about the battery.

The aJAZZ+ also supports Qi wireless charging, not just USB-C. Just set it on a compatible charger — no plugging and unplugging cables every time. Smart. Of course, charge it outside the bathroom after it’s dry.

That said, stereo pairing could be easier to figure out

I love the aJAZZ+, but it’s not without complaints. First, figuring out how to pair two for stereo isn’t very clear.

I like how minimal the design is, but that also makes the controls less intuitive. At first I wasn’t sure, “Is this actually in stereo now?”

The other issue: after pairing, it’s hard to tell which is left and which is right.

The aJAZZ+ doesn’t have a left/right test feature, so I used an L/R test tone and software that pans sound left and right to check.

Since stereo with two is so great, it’d be way easier if it announced “LEFT” and “RIGHT” when connecting, or let you check in an app.

Still, music in the bath is on another level compared to built-in bath speakers

I’ve used bath speakers from YAMAHA and others before, but running two aJAZZ+ made me realize “sound playing in the bath” and “enjoying music in the bath” are completely different things.

Of course, built-in bathroom speakers and portable Bluetooth speakers have different purposes and installation, so it’s not a fair spec comparison.

But in my own experience of “does listening feel good?”, the aJAZZ+ was on another level.

Especially classical. Strings and piano spreading through the bathroom without bass getting in the way — once you experience it, it’s pretty addictive.

The biggest reason I love the aJAZZ+ isn’t the specs.

It makes me think, “What should I listen to in the bath today?”

I’ve used plenty of waterproof and bath speakers, but the aJAZZ+ is the first that made me want to take a bath just to listen to music.

I’d never found a speaker like this before.
