Marshall Stockwell III Launched 7 Years After Second-Gen Model With Upgraded Replaceable Battery: Price, Features

Marshall has unveiled the Stockwell III portable Bluetooth speaker, marking the first update to the Stockwell series in seven years. The new model arrives with a larger battery rated for more than 40 hours of playback on a single charge, alongside improvements in durability and repairability.
