Marshall Stockwell III: A New Standard for Outdoor Audio
The Marshall Stockwell III is a significant upgrade over its predecessor, offering improved durability, longer battery life, and enhanced sound performance. It features a robust IP55 rating, a replaceable battery for longevity, and a 'True Stereophonic Sound' system that ensures consistent audio from any angle. While it offers a warmer, smoother sound profile compared to competitors like the JBL Charge 6, it excels in vocal clarity and consistent performance across various environments.
Design and Build
The Stockwell III maintains the iconic Marshall aesthetic with a detachable handle and a premium feel, now utilizing more recycled materials. It features a boosted IP55 rating, making it more resistant to dust and water than previous models. The control layout has been simplified with dedicated buttons for power and Bluetooth, alongside a customizable 'M-button' and a dedicated media jog.
Key Features and Connectivity
Equipped with Bluetooth 5.3 and multipoint technology, the Stockwell III allows for seamless switching between two devices. It supports Auracast for broadcasting to other compatible speakers and features a dual-purpose USB-C port that can function as a power bank. A standout feature is the ability to mix sources, allowing users to play audio from a wired connection and a Bluetooth device simultaneously.
Battery and Performance
The speaker boasts a substantial battery life of over 40 hours on a single charge. A major leap in sustainability is the inclusion of a replaceable battery, which can be serviced directly through Marshall. It also supports fast charging, providing significant playback time with just 20 minutes of charging via a 30W USB-C PD charger.
Sound Quality Analysis
The Stockwell III delivers a 'warm' and 'weighty' sound profile. While it may not have the raw punch of some competitors, it provides excellent midrange clarity and smooth treble. The 'Dynamic Loudness' ensures a balanced experience at any volume, and the 'Soundstage' mode allows users to choose between a tighter, punchier sound or a wider, more airy presentation.
