Marshall launches Stockwell III Bluetooth speaker with 40‑hour battery life

Marshall has introduced the Stockwell III, the first major refresh of its portable Bluetooth speaker line in seven years. The speaker retains the brand’s guitar‑amp‑inspired design with a PU‑leather strap, brass control panel, metal grilles and textured silicone sleeve, and is offered in black, brass and cream finishes.

Key upgrades include a user‑replaceable battery that provides more than 40 hours of playback—double the runtime of the previous model—and a USB‑C port that also allows the speaker to function as a power bank. The device carries an IP55 rating for dust and water resistance, features Marshall’s True Stereophonic 360‑degree sound technology, and offers a dedicated M‑button for presets and track control. Pricing is $249.99 in the United States and A$359 in Australia.
