Marshall Emberton III
The Emberton III is the portable powerhouse of the Marshall family. It boasts a rugged, waterproof build with IP67 dust and water resistance, making it perfect for outdoor adventures or just moving from room to room without worry. Weighing just 1.5 pounds, it’s deceptively small for the big, balanced sound it puts out—thanks to True Stereophonic technology that ensures 360° audio dispersion. The retro control knob on top adds a tactile charm, while Bluetooth 5.3 ensures quick pairing and stable connectivity. The Emberton III also supports Auracast for future-forward multi-speaker broadcasting, though it doesn’t allow traditional party pairing with other units.
It’s tuned for clarity and presence, with defined mids and surprisingly deep low-end for its size. This is the speaker you toss in your backpack for beach days, backyard BBQs, or impromptu jam sessions. The 30+ hour battery life means you’ll run out of energy before your Emberton does.

Though smaller than the Emberton, it still brings Marshall’s signature sound with a full-range driver and dual passive radiators that push out punchy mids and bright highs.
You’ll appreciate the soft silicone strap on the back, which makes it easy to attach to backpacks, handlebars, or shower caddies. The single gold multi-function joystick is intuitive and stylish, allowing volume, track, and power control all in one.
It may not fill a room like the larger models, but it’s ideal for solo listening, hiking, and travel. With rugged durability and a minimalist vibe, the Willen II is for the music lover who’s always on the move.

You get clean mids, deep bass, and clear highs at any volume, and onboard treble/bass knobs let you shape your sound just like a guitar amp.
Its True Stereophonic design delivers room-filling, multi-directional sound that’s ideal for backyard hangs or hotel room parties. The 20+ hour battery gives you serious playtime, and it’s tough enough for casual outdoor use despite a modest water resistance rating.

At just over 3 pounds, it’s lighter than the Kilburn and even more versatile thanks to its USB-C charging and phone-charging capability.
The sound is detailed and surprisingly immersive for a speaker this size, thanks to its multi-directional drivers. The onboard knobs give you classic Marshall-style EQ control, and the battery can last more than 20 hours at moderate volume.
If you’re looking for a reliable mid-sized speaker that won’t quit on the go, Stockwell II is a dependable rockstar in disguise. It’s equally at home on your desk or in your gear bag.

This is a perfect speaker for offices, bedrooms, or small living rooms, with just enough presence to keep you engaged without overwhelming the space. You’ll find Bluetooth 5.2 support and on-device bass/treble knobs that make it easy to tune your listening experience.

This model features Bluetooth 5.2 with LE audio for future-proof streaming and a wider frequency response than the Acton. The on-device controls give it that Marshall amp feel, and dual RCA and AUX ports provide analog input options too.

It packs two 3/4″ tweeters and dual 6″ woofers driven by 120 watts of clean, room-filling output.
Beyond its sonic upgrades, the Woburn III adds an HDMI ARC port, making it an ideal centerpiece for home theater setups. It also supports Bluetooth 5.2 with LE Audio (future-ready for higher-quality streaming) and offers app-based EQ tuning. RCA and AUX inputs are still on board, but the addition of HDMI modernizes it significantly.
This is not a speaker for the faint of heart—it’s large, loud, and built for serious listening. If you want a speaker that looks like a vintage amp but roars like a concert stack, the Woburn III is your top-shelf pick.
