Marshall Willen II

Name: Marshall Willen II
Brand: Marshall
SKU: 2975

Manufacturer: Marshall

The Marshall Willen II is a compact portable speaker designed for on-the-go use, built around an IP67-rated waterproof and dustproof enclosure that can handle submersion up to one meter. Weighing 360 grams and measuring 100.5 mm on each side with a 43.4 mm profile, it strikes a balance between portability and presence. A passive radiator works alongside the single driver to extend the low-end response, with a stated frequency range running from 75 Hz up to 20,000 Hz.

Connectivity is handled through Bluetooth 5.3, which supports both LE Audio and Auracast, with a maximum wireless range of 100 meters. The speaker delivers 38W of audio output from a single driver channel, reaching a sound pressure level of 88 dB/mW. Battery life is rated at 17 hours with a 2.5-hour charge time via the USB Type-C port, and a battery level indicator is included. Additional features include a sleep timer, voice prompts, a physical control panel on the unit itself, and smartphone remote support through a companion app.

Pros

IP67 rating means it is fully dustproof and can be submerged in water up to one meter, making it well-suited for outdoor or wet environments
17-hour battery life allows extended use between charges, with a relatively short 2.5-hour recharge time
Bluetooth 5.3 with LE Audio and Auracast support adds modern wireless broadcasting capability rarely found at this size
A passive radiator helps extend low-frequency response down to 75 Hz within a compact 360-gram enclosure
USB Type-C port is used for charging, a current and widely compatible standard
A battery level indicator removes guesswork about remaining charge during use

Cons

No stereo speaker configuration or stereo pairing support limits the audio to a single-channel mono output
No aptX, AAC, LDAC, or any other advanced Bluetooth audio codec is supported, restricting audio transmission options
Neither a 3.5 mm audio jack nor an AUX input is available, making wired audio playback impossible
Wireless charging is not supported, requiring a cable to recharge
The microphone does not feature noise cancellation, which may affect call clarity in louder settings
No mute function is available, which can be inconvenient during calls or when temporarily silencing playback

Who is this for?

This speaker is a strong fit for users who frequently take it into demanding outdoor environments — its IP67 waterproof rating with one-meter submersion tolerance makes it a practical choice for beach trips, hiking, or poolside use without concern for water or dust damage. The 17-hour battery life supports full-day outings without needing a recharge, and the compact 360-gram form factor means it travels easily. Users who value modern wireless standards will also appreciate the Bluetooth 5.3 with LE Audio and Auracast support, which suits those who want to broadcast audio to multiple listeners simultaneously.

Who is this NOT for?

This speaker is less suited to users who prioritize high-fidelity stereo playback, as it outputs a single-channel mono configuration with no stereo pairing option. Listeners who rely on advanced Bluetooth codecs such as aptX, AAC, or LDAC for higher-quality wireless audio will find no support for any of them here. It is also a poor match for those who need wired audio connectivity, since there is no 3.5 mm jack or AUX input available, and anyone hoping to use it for hands-free calls in noisy settings will be limited by the standard single microphone with no noise cancellation.

Final Verdict

The Marshall Willen II is a compact portable speaker built around a clear set of priorities: outdoor resilience, extended battery life, and modern wireless connectivity. Its IP67 waterproofing combined with 17 hours of playback makes it a dependable companion for users who spend time in unpredictable environments and need a speaker that keeps up without constant recharging. The addition of Bluetooth 5.3 with LE Audio and Auracast support positions it at the more capable end of the wireless spectrum for this form factor. That said, its mono-only output, absence of advanced audio codecs, and lack of any wired audio input mean it is not designed for the discerning listener seeking high-fidelity or versatile connectivity. For users whose main concern is durability and all-day wireless use in outdoor settings, the Willen II delivers a focused and coherent feature set; those with broader audio demands will need to look elsewhere.
