Marshall has launched the Stockwell III, its first update to the portable Bluetooth speaker line in seven years.
The new model arrives with a user-replaceable battery, a feature that aligns with upcoming EU regulations.
The Stockwell III retains the classic guitar amp-inspired design with a metal mesh grille, brass control panel, and a velvet-lined strap handle.
Under the hood, it offers over 40 hours of playback, doubling the battery life of its predecessor.
Key Upgrades and Features
The speaker now has an IP55 rating for dust and splash resistance. It charges via USB-C and can function as a power bank for other devices.
Audio improvements include True Stereophonic technology for 360-degree sound and dynamic loudness processing to maintain balanced audio at any volume.
A dedicated M-button on the top panel provides access to presets and track controls.
Marshall has focused on repairability: the battery, carry strap, grilles, silicone sleeve, and carrying case are all user-replaceable.
This move comes ahead of EU mandates requiring replaceable batteries in consumer electronics starting next year.
The Stockwell III is available in black and brass or cream color options, priced at $249.99 in the US.
