The Marshall Willen is a compact portable Bluetooth speaker designed for those who want a reliable sound companion wherever they go. It delivers 10 W RMS of power through a 2-inch full-range driver and two passive radiators, covering a frequency range from 100 Hz to 20,000 Hz. This small device connects via Bluetooth 5.1 with a range of 10 meters, and you can easily manage its settings through the Marshall Bluetooth app on your phone. Its rugged build features a rubberized PVC finish and an IP67 rating, meaning it is fully protected against dust and can withstand being submerged in water. The speaker weighs only 310 g and measures roughly 101 by 100 millimeters, making it easy to slip into a bag. A practical mounting strap on the back allows you to attach it to bike handlebars or other surfaces for hands-free listening. Power is handled by a lithium-ion polymer battery that provides over 15 hours of playback on a single charge. When you are running low, a full recharge via USB-C takes 3 hours, though a quick 20-minute charge is enough to give you another 3 hours of music. A tactile control knob on the front handles both power and volume, providing a physical way to adjust your audio experience.
