Overview
Immersive 360-Degree Sound
Thanks to its distinct stereo arrangement, this Marshall Kilburn 3 Portable Bluetooth Speaker delivers a true 360-degree audio experience with no blind spots. Thus, whether you’re in front of it or off to the side, you’ll still enjoy crisp highs, rich mids, and deep bass. Moreover, improved tuning and wide-band drivers ensure that sound quality remains balanced across all genres and volumes.
Consistent Sound with Dynamic Loudness
Designed with dynamic loudness functionality, this Bluetooth speaker maintains audio clarity even at high volume. Hence, turning it up doesn’t distort the sound; instead, the bass, mids, and treble adjust automatically for a full-bodied listening experience.
Intuitive Tactile Controls
Equipped with signature Marshall tactile controls, this portable speaker allows you to fine-tune bass and treble, control playback, and switch presets via the M-button. Thus, you stay in complete control of your sound without relying on a phone or app.
Convenient Charging Bank
Integrated with a USB charging port, this Bluetooth speaker can also act as a power bank for your smartphone. So, whether you're at a park or travelling, simply plug in and keep your phone charged, ensuring your music never stops.
Extended Portable Playtime
Delivering over 50 hours of battery life on a single charge, this portable speaker keeps your music going long after the party starts. So, whether you're playing mellow acoustic tracks on your balcony or energising rock tunes at a backyard gathering, the music continues without interruption. Hence, your playlist is more likely to run out than the battery itself.
Dust and Water Resistance
With an IP54 rating, this Marshall Kilburn 3 speaker can handle the occasional splash or a dusty environment with ease. So, if a drink spills during a party or you're enjoying tunes in a breezy garden, the Kilburn III is built to keep playing. Additionally, it’s suitable for outdoor patios, poolside lounging, or impromptu road trips.
