Marshall has introduced its latest portable Bluetooth speaker, the Stockwell III, aiming to offer significant upgrades while retaining the original price point of its predecessor.

Launched on June 9, the Stockwell III is priced at $249.99, identical to the Stockwell II released seven years ago. This decision stands out in a market where tech product prices often increase with each generation. Key improvements include a doubled battery life, now offering 40 hours of playback, and an enhanced IP55 rating for dust and water resistance, an upgrade from the previous model's IPX4. The speaker also features new audio drivers, including a three-inch woofer and two 1.75-inch wide band drivers, with Marshall's True Stereophonic technology promising 360-degree sound. USB-C charging is now standard.

A notable feature of the Stockwell III is its emphasis on longevity through modular and replaceable parts. Components such as the battery, grilles, silicone sleeve, and carrying case are designed to be easily swapped out, extending the product's usable life and potentially reducing electronic waste. The speaker incorporates a silicone sleeve, a PU leather strap with velvet lining, and a brass control panel, combining aesthetic appeal with durable materials. It measures 7.1 x 5.9 x 2.8 inches and weighs 2.9 pounds. The Marshall Stockwell III will be available for purchase starting August 4 through Marshall's official website and at Costco, in classic black, brass, and cream color options.
