Marshall Willen Portable Bluetooth Speaker (Black & Brass)

Marshall Willen Portable Bluetooth Speaker (Black & Brass)

The Marshall Willen Portable Bluetooth Speaker (Black & Brass) is the smallest speaker Marshall makes, a compact square that measures barely ten centimetres across and is built to leave the house with you. It takes the visual identity the brand is known for — a black finish with brass-coloured detailing and a metal grille — and puts it into a rugged, pocketable body with a rubber mounting strap on the back. Behind that grille sits a single 2-inch full-range driver supported by two passive radiators, driven by a 10 W Class D amplifier. The result is a mono speaker tuned for close, personal listening: on a desk, beside a tent, on a balcony or clipped to a bag, it delivers clear vocals and a fuller low end than its size suggests, with a maximum sound pressure level of 82 dB at one metre.

Key Features

• One 2-inch full-range driver: A 10 W dynamic driver with two passive radiators, in a sealed cabinet with passive radiator design, for clear mono sound from a very small enclosure.
• 15+ hours of portable playtime: A full charge takes 3 hours, and a 20-minute quick charge gives 3 hours of playtime when time is short.
• IP67 dust and water resistance: The Willen is dust-tight and water-resistant to the IP67 rating, so rain, splashes and dusty outdoor use are part of its intended working life.
• Bluetooth 5.1: Wireless streaming with a range of 10 metres in open field, paired through a dedicated Bluetooth pairing button.
• Stack Mode: Connect multiple Willen speakers together in Stack Mode to build a bigger sound from several small speakers.
• Built-in microphone: Take and end calls hands-free through the speaker, controlled from the multi-directional control knob.
• Mounting strap: The rubber strap on the rear lets you fasten the speaker to a bag, handlebar or rail so it stays put while it plays.

Sound From a Speaker This Small

A speaker of this size cannot move air the way a bookshelf cabinet does, and the Willen does not pretend otherwise. Its frequency response runs from 100 Hz to 20,000 Hz, which covers the body of voices, guitars, podcasts and most of what makes music recognisable. The two passive radiators work with the sealed cabinet to give the low end more weight than a single small driver would normally produce, so kick drums and bass lines register as a solid foundation rather than a thin suggestion. Mono playback is the right choice at this size: instead of a narrow, artificial stereo image, you get one clear point of sound that stays consistent wherever you sit in relation to it. For near-field and small-space listening, that focus is a strength.

Built for Dust, Water and Travel

The IP67 rating is central to what the Willen is for. It can be taken to the beach, used beside a pool, carried on a hike or left on a workshop bench without the caution a home speaker demands. The body is compact at 101.6 x 100.5 x 40.4 mm and light at 0.31 kg, so it drops into a jacket pocket, a side pouch or the corner of a day pack. Marshall also notes that 60 percent of the plastic used in the product is recycled plastic, excluding plastic in electronic components, which suits a product designed to be carried for years rather than replaced. The black and brass finish keeps the classic Marshall look intact outdoors, with the brass-coloured knob and detailing contrasting against the black grille and body.

Battery, Charging and Stack Mode

Playtime is rated at more than 15 hours, which covers a full day out or several evenings of desk listening between charges. Charging is through USB-C, and the quick-charge function is genuinely useful: 20 minutes connected gives around 3 hours of playtime, enough to rescue a speaker you forgot to charge before leaving. A full recharge takes 3 hours. When one Willen is not enough for the space, Stack Mode lets you connect multiple Willen speakers and play through them together, spreading sound across a larger area or a group spread around a campsite or garden.

Controls, Calls and the Marshall Bluetooth App

Day-to-day control happens on the speaker itself. The multi-directional control knob handles power, play and pause, track skipping, volume and answering or ending calls, so the phone can stay in a pocket. A separate Bluetooth pairing button keeps connecting a new device simple, and a battery indicator shows the charge state. The built-in microphone means calls come through the speaker clearly enough for hands-free conversation. Willen also works with the Marshall Bluetooth app, which provides equaliser adjustments and over-the-air updates, letting you shape the sound a little without touching the hardware controls.

The Willen is Marshall sound reduced to its essentials: one well-tuned driver, a tough IP67 body, long battery life and a strap that makes it genuinely portable. For personal listening at home, at work or outdoors, it offers the brand character and build of the larger Marshall speakers in a form you can carry anywhere without planning around it.
