Marshall WILLEN II

Marshall WILLEN II｜Compact, portable, IP67 waterproof Bluetooth speaker with powerful bass

An IP67 waterproof Bluetooth speaker you can take anywhere

Marshall WILLEN II is an IP67 waterproof Bluetooth speaker from Marshall, featuring a 38W Class D amplifier, 1 x 2-inch 10W full-range driver, and 2 passive radiators. It offers 17+ hours of battery life, Bluetooth 5.3 LE, and a wireless range of up to 100 meters. Whether you want to bring music outdoors on your commute, need a durable small speaker for a picnic in the park, or want a device for both playback and hands-free calls while working from home, WILLEN II delivers more sound than you’d expect from such a small body.

Compared with traditional compact portable speakers of similar size but weak bass, the Marshall Bluetooth speaker WILLEN II uses a slightly larger enclosure, improved acoustic design, and passive radiator structure to achieve deeper bass and a more balanced full-range performance. Compared with similar outdoor Bluetooth speakers focused on portability, its strengths are IP67 dust and water resistance, hands-free calling, Bluetooth LE Audio-ready support, and Marshall’s signature sound, making its positioning very clear.

Marshall WILLEN II core technology and features

Marshall signature sound tuning: Built around a balanced and clear full-range presentation, with more impactful bass output so a small speaker can still sound full and substantial.
Improved acoustic structure and deeper bass: Marshall says WILLEN II delivers a clear upgrade over the previous generation, with deeper bass extension and stronger low-end presence thanks to the slightly larger body.
Driver and passive radiator setup: It includes 1 x 2-inch 10W full-range driver plus 2 passive radiators, using a sealed enclosure and passive radiator design to enhance bass extension and energy.
38W Class D amplifier: Powered by a 38W Class D amplifier for efficiency, control, and the low power consumption needed in a portable device.
17+ hours of portable playback: A single charge provides over 17 hours of playtime, making it reliable for all-day outdoor activities, travel, or workday use.
Fast charging support: A 20-minute quick charge gives about 5.5 hours of playtime, making last-minute top-ups easy.
IP67 dust and water resistant body: Rated IP67, it can be submerged in up to 1 meter of water for up to 30 minutes, offering better resistance to rain, sand, splashes, and outdoor conditions.
Built-in microphone for hands-free calls: You can answer calls directly through the speaker, keeping your hands free for work, cooking, packing, or moving around.
Bluetooth 5.3 LE and LE Audio-ready: Supports Bluetooth 5.3 LE and is prepared for future LE Audio use, offering long-term connectivity compatibility and Auracast™ potential.
Up to 100-meter Bluetooth range: In open, unobstructed environments, the wireless range can reach up to 100 meters for greater outdoor flexibility.
Bluetooth Multipoint connection: Connects to 2 devices at once and remembers up to 8 paired devices, making it easier to switch between phone, tablet, or laptop.
Multi-directional control knob: The top panel features a multi-directional control knob for play/pause, previous/next track, volume adjustment, answer/end call, and reject call functions.
5-level battery indicator: The 5-step battery light lets you quickly check remaining power without opening an app every time.
Rubber strap design: It can stand upright, lie flat, hang, or be attached to objects, giving you more freedom for outdoor carrying and placement.
Marshall Bluetooth app compatibility: Works with the Marshall Bluetooth app on iOS and Android for firmware updates and related settings management.
More repairable and sustainable design: Marshall offers authorized repair service and spare parts support, and uses some recycled plastic and PVC-free materials to extend the product lifecycle.
70% recycled plastic content: 70% of the plastic in the product comes from GRS-certified post-consumer recycled plastic, including materials from used electronic devices and CDs.

Marshall Signature Sound acoustic tuning

WILLEN II centers on balanced sound, keeping bass, mids, and highs clearly separated at different volumes instead of emphasizing only one range.
Marshall specifically highlights stronger bass presence and deeper low-end extension than the previous generation, making it a good fit for pop, electronic, rock, and rhythm-driven music.

Driver setup and enclosure structure

It uses 1 x 2-inch 10W full-range driver, matching a mono playback design to keep the body compact and the sound focused and direct.
Two passive radiators with a sealed enclosure improve bass feel and transient response within a limited volume, helping overcome the natural bass limits of small speakers.

17+ hours of battery life and fast charging

A single charge provides over 17 hours of playtime, enough for a full day outdoors, background music during the workday, or short trips.
A 20-minute quick charge delivers about 5.5 hours of battery life, which is especially useful for last-minute outings or topping up on the go.

IP67 dust and water resistance and outdoor durability

With an IP67 rating, it is dustproof and can be submerged in up to 1 meter of water for up to 30 minutes, giving you more confidence in rain, splashes, sand, and poolside use.
The official manual still recommends making sure the body is completely dry before charging, which helps with safety and long-term durability.

Bluetooth 5.3 LE and multi-device connection

Supports Bluetooth 5.3 LE, providing a modern wireless foundation and preparing for future LE Audio use cases.
It can connect to 2 devices at once and remember up to 8 paired devices, then reconnect to the most recently used device when back in range.

Built-in microphone and hands-free call controls

The built-in microphone lets WILLEN II double as a speakerphone, so you can answer, end, or reject calls directly with the control knob.
The manual says you can switch calls between the speaker and your phone using the Bluetooth button, making work and everyday use more intuitive.

Strap design and flexible placement

The body includes a rubber strap, so it can stand upright, lie flat, attach to objects, or hang for use, giving you more freedom for outdoor scenes and desktop placement.
For bikes, camping gear, backpack mounting, bathroom hanging, or narrow desks, this structure is more flexible than a simple flat-base design.

Marshall Bluetooth app and firmware management

Supports the Marshall Bluetooth app for firmware updates and management on iOS and Android devices, helping keep features and stability up to date.
Marshall also notes that you can choose a battery protection level in the app, which helps tailor battery-life management to your usage habits.
