Marshall Stockwell III Doubles Battery And Keeps Its Old Price
Marshall just revealed the Stockwell III with a replaceable 40-hour battery, holding the same $249.99 price seven years on.
Key Takeaways
- Battery life doubles to 40 hours while the price holds at $249.99, matching the seven-year-old Stockwell II.
- A replaceable battery and swappable parts signal Marshall's wider push toward repairable, regulation-ready audio gear.
- Coverage splits on the launch date, with two sources citing August 4 and Forbes listing August 18.
Marshall has announced the Stockwell III, the first update to its portable Bluetooth speaker since 2019. The headline change is a battery that now lasts 40 hours, doubling the previous generation's runtime.
According to a report from Mashable, the speaker was announced on June 9 at a price of $249.99. That figure matches the Stockwell II, which launched roughly seven years earlier.
The Stockwell III leans heavily into repairability, a direction shaping much of consumer electronics today. Several parts can be swapped to extend the product's usable life and improve its resale value.
According to The Verge, the replaceable parts include the battery, the carrying strap, the front and back grilles, and the silicone sleeve. The same report notes this battery approach echoes Marshall's recent wireless headphones.
The Verge links the shift toward a user-replaceable battery to new EU regulations now affecting many electronics brands. Forbes similarly frames the move around right-to-repair legislation and rising demand for sustainable products.
Sound remains a core selling point, with True Stereophonic 360-degree audio aimed at filling a room evenly. Forbes reports the design avoids dead zones, letting the speaker sit anywhere without losing balance.
According to Forbes, a Dynamic Loudness feature balances bass, mids, and treble across volume levels. At lower levels, the bass and treble are boosted to preserve detail and clarity.
Durability also improved, with the water and dust rating rising from IPX4 to IP55. According to The Verge, that change makes the speaker better suited to splashes and dusty outdoor use.
The brass control panel gained an M-button for jumping to preset sound profiles directly on the speaker. The Verge also notes a dedicated media button for pausing, playing, or skipping tracks.
According to Mashable, the speaker measures 7.1 by 5.9 by 2.8 inches and weighs 2.9 pounds. The same source lists one 3-inch woofer paired with two 1.75-inch wide-band drivers.
The built-in battery can also work as a power bank to top up other devices over USB-C. According to The Verge, that charging detail adds practical value for travel and outdoor use.
Availability dates differ across the coverage, so buyers should watch official channels closely. Mashable and The Verge both cite an August 4 launch, while Forbes lists August 18.
According to Mashable, the Stockwell III will sell through Marshall's website and at Costco. The speaker arrives in Black, Brass, and Cream finishes for the announced price.
