Marshall has been on a roll in 2026, adding to its lineups of headphones, home speakers, and now, portable Bluetooth speakers. For the past couple of weeks, I’ve been testing the Marshall Stockwell III which succeeds the seven-year-old Stockwell II — and it has quickly become my go-to speaker for almost everything.
The Stockwell III improves on its predecessor by doubling the battery life (over 40 hours now), being more waterproof thanks to its IP55 rating, and delivering punchier bass, brighter treble, and incredible 360° sound. Though a little expensive and slightly heavy for a portable speaker, those feel like minor issues in an otherwise compelling (and beautiful) package.
