JBL Bandbox: New Bluetooth speakers with AI stem separation – a game-changer for practice sessions?

NAMM 2026 is done and dusted, but we’re still on a mission to alert you to as many new product launches as we can. And this release from JBL is certainly worth knowing about.

Meet the BandBox, a new line of practice amp/speakers loaded with AI vocal and instrument separation technology for supercharged practice sessions. Think of it like a portable Bluetooth speaker with a bunch of powerful musician-focused features.

The line comprises two BandBox units: the 30W BandBox Solo – tailored for individuals looking to upgrade their practice setup – and BandBox Trio, which is designed more for group situations, with four instrument inputs and a more powerful speaker configuration, with 135W powering one 6.5” woofer and two 1” tweeters.

BandBox Solo

The ability to utilise AI-powered stem separation to subtract your instrument from a mix and play along will no doubt prove a tantalising prospect for musicians looking to upgrade their practice setup.

The BandBox Solo features a single guitar/mic input – ideal for guitarists or singer-songwriters – and allows the player to stream songs via Bluetooth, and use JBL’s Stem AI to reduce or completely remove specific elements of a track.

The Solo also boasts a built-in looper, as well as a pitch shifter, tuner and integrated LED screen, while the JBL ONE app is on hand with a healthy selection of vintage and modern amp models, and effects including phaser, chorus and reverb.

You can also connect wired headphones for silent practice, and there’s also a USB-C output for recording your sound straight into your DAW of choice.

Of course, it isn’t just a practice amp, the JBL BandBox Solo can also simply be used as a regular Bluetooth speaker.

BandBox Trio

Meanwhile, the BandBox Trio packs a bigger punch, and is aimed at “small bands, jam sessions or duos who want to perform together without the need for a full setup”.

You can balance levels, craft tone and apply effects directly on the speaker unit via a built-in four-channel mixer, while the unit also features a replaceable battery, meaning you can simply swap power packs and accommodate longer practice sessions without the fear of running out of charge.

Like the BandBox Solo, the Trio also features a built-in tuner, metronome and looper, integrated LCD colour screen, Stem AI instrument separation technology, and added control via the JBL ONE app. There’s also a USB-C output for connecting the Trio to your computer for direct recording into your DAW.

What is JBL saying about BandBox?

“JBL BandBox is created with musicians’ needs in mind, and made possible by cutting-edge technology,” says Carsten Olesen, President of Consumer Audio at HARMAN, JBL’s parent company.

“This is the first speaker to feature an on-device Stem AI algorithm capable of removing vocals or instruments, without the need for cloud processing or an internet connection. With this breakthrough, it’s easier than ever to practice, improve and enjoy playing music either on your own or with friends.”

Pricing and availability

Both the BandBox Solo and Trio will be available from February, priced at £199 and £529, respectively.
