Marshall has unveiled its latest portable Bluetooth speaker, the Stockwell III, aimed at users seeking powerful sound without compromising on portability. This speaker incorporates Marshall's innovative 'True Stereophonic 360-degree' sound technology, which is designed to fill any space with rich and expansive audio. It also features a 'Dynamic Loudness' function that automatically adjusts bass, mid, and treble frequencies to maintain clarity at any volume. The Stockwell III offers an impressive battery life of around 40 hours and is rated IP55 for dust and water resistance, enhancing its portability. Additionally, it can double as a charging bank for smartphones and other devices. The design is reminiscent of a mini guitar amplifier, complete with a leather carry strap and the iconic Marshall logo on the external grille. Simon Berbec, Product Manager at Marshall Group, highlighted the advancements in technology since the launch of the Stockwell II in 2019, noting improvements in battery life, acoustics, and protection features. The Stockwell III will be available starting August 25, priced at £200 or $250.
