15+ Hours of Portable Playtime

The Willen provides 15+ hours of wireless playtime on a single charge, making it suitable for long listening sessions away from a power source.

Actual battery life can vary according to volume level, environmental conditions, battery condition, and usage.

Quick Charging

When the battery is running low, Willen supports convenient quick charging.

20 Minutes Charging = Approx. 3 Hours Playtime

A complete battery recharge takes approximately 3 hours.

USB-C Charging

Willen uses a modern USB-C charging connection.

This eliminates the need for older Micro-USB charging cables and makes it convenient to recharge using a compatible USB power source.

IP67 Water & Dust Resistance

The Marshall Willen carries an IP67 rating, providing strong protection against both dust and water.

IP67 Means:

• 6: Dust-tight protection
• 7: Protected against temporary immersion in water under standardized test conditions

This makes Willen suitable for outdoor environments, travel, poolside use, and other situations where a conventional indoor speaker may be less practical.

Important Water-Resistance Note

IP67 does not mean the speaker should intentionally be used underwater.

Water resistance can also decrease over time because of normal wear or physical damage. Make sure the charging area is dry before connecting a charging cable.

Bluetooth 5.1

Willen uses Bluetooth 5.1 for wireless audio connectivity.

Wireless Specifications

• Bluetooth Version: 5.1
• Wireless Range: Approx. 10m / 30ft
• Wireless Connection: Bluetooth
• 3.5mm AUX: No

It can connect to compatible smartphones, tablets, computers, and other Bluetooth audio sources.

Stack Mode

Marshall's Stack Mode allows multiple compatible Willen speakers to be connected together for a larger multi-speaker listening experience.

This is useful for users who want to expand the sound across a larger area using additional compatible speakers.

Additional speakers are sold separately.

Built-In Microphone

Unlike many compact music-focused portable speakers, Willen incorporates a built-in microphone.

This allows the speaker to be used for hands-free calls when paired with a compatible smartphone.

Multi-Directional Control Knob

The integrated control knob provides convenient physical control directly from the speaker.

Depending on the current function, users can control:

• Power
• Play / Pause
• Previous Track
• Next Track
• Volume Up
• Volume Down
• Calls

This allows common functions to be managed without constantly using the connected phone.

Built-In Mounting Strap

A flexible mounting strap on the rear makes Willen easy to attach or position in different locations.

It can be useful for:

• Backpacks
• Outdoor Setups
• Travel
• Camping
• Bikes
• Home Use
• Desk Setups

Always make sure the speaker is securely attached before carrying or mounting it.

Marshall Bluetooth App

The Willen works with the Marshall Bluetooth app on compatible mobile devices.

The app can provide supported functions such as:

• EQ Adjustments
