True Stereophonic 360° Sound
One 3" woofer and two 1.75" wide-band drivers, powered by a 65W + 2x31W Class D amplifier design, deliver Marshall's signature multidirectional sound from every angle.
40+ Hour Battery Life
A user-replaceable battery delivers over 40 hours of playback on a single charge — twice the runtime of the previous Stockwell II.
Fast USB-C Charging
A 20 minute quick charge adds 7 hours of playtime, and a full charge takes under 3 hours with a 30W USB-C PD charger. The same port doubles as a power bank, outputting 5V/3A to charge other devices.
IP55 Dust and Water Resistant
Built to handle low-pressure water jets from any angle, making it equally at home by the pool, at the beach, or caught in the rain.
Bluetooth 5.3 with Auracast
Multipoint connectivity and Auracast broadcast support with a stable 10m wireless range, plus SBC, LC3, and AAC codec support.
Real Repairability
The battery, carrying strap, front and back grilles, and silicone sleeve are all user-replaceable, extending the speaker's usable life well beyond a typical charge cycle.
Tactile Analogue-Style Controls
Physical bass, treble, and volume dials sit alongside a media jog and dedicated Bluetooth button for quick control without reaching for your phone.
Guitar-Inspired Design
A genuine leather carrying strap and Marshall's iconic amp-inspired styling, built from 27% recycled materials by weight.
40+ Hours Playback
A user-replaceable battery delivers over 40 hours of playback on a single charge with fast USB-C quick charging.
Power Bank Function
The same USB-C port outputs 5V/3A to charge your phone or other devices when you need it.
Real Repairability
The battery + carrying strap + grilles + silicone sleeve are all user-replaceable for a longer usable life.

Handles low-pressure water jets from any angle - equally at home by the pool + at the beach + in the rain.
