Turning heads all these decades later, the Kilburn III Portable Bluetooth Speaker from Marshall is another example of how Marshall is continuing their legacy of timeless design and powerful sound. With the Kilburn III, you get portable convenience and a speaker that can handle being taken outside, with a durable water- and dust-resistant construction. You and your friends can put the Kilburn III anywhere, as its 360° true stereophonic sound can be heard clearly from any direction. It pumps out up to 50W of audio power that can be played for days with over 50 hours of playback time. Thanks to Dynamic Loudness, that streaming Bluetooth music will sound great at any volume, and with Auracast, you can share it with any compatible device that's nearby.

Share with Auracast

Auracast technology lets you stream audio to other Auracast-compatible speakers nearby, like a radio station, all without the chore of pairing to each and every speaker.

Dynamic Loudness

Marshall understands the joy of playing music loud, which is why they added dynamic loudness to the Kilburn III. No matter the volume you set the speaker to, it will automatically adjust the bass, mids, and highs accordingly to keep your music sounding perfect.

Also a Power Bank

The built-in speaker will give you up to 50 hours of playback, but it will also provide essential power for a smartphone, tablet, or other USB-C mobile device.

Made to Last

Marshall purposely designed the Kilburn III to last for years under normal wear and tear. You can even bring it to Marshall for servicing and the battery can be replaced over time.

Responsible Construction

The materials of the Kilburn III are eco-friendly and responsibly sourced, with 84% of the plastic used in the speaker being recycled. The speaker is also entirely PVC-free, wrapped in DMFa-free, water-based vegan leather, and has a post-consumer polyester backing.

Marshall Mobile App

Use the mobile app to manage playback, activate battery preservation mode, adjust bass and treble, download OTA updates, customize the tactile M-button on the speaker, and more.

50+ Hours Of Portable Playtime

A speaker for inside and outside your home. Start track one in the bedroom, then listen to the encore on the balcony. With 50+ hours of portable playtime, your playlist will probably run out before the battery.

True Stereophonic

360° sound finds you wherever you're standing thanks to a stereo arrangement with no blind spot. Take in well-rounded mids, crisp highs, and bass that digs deep with improved tuning and wide band drivers.

Dust & Water-Resistance (IP54)

Kilburn III’s IP54 dust and water-resistant design make s it ready to deal with a splash of water or a bit of dirt. It won’t be bothered about a little spill from an overexcited house guest either.

Dynamic Loudness

Turn the music right up without compromising on any musical detail. Kilburn III has been designed so that the bass, mids, and treble adjust perfectly no matter the volume.

Tactile Controls

Whether you want to customise your bass and treble, turn your speaker on or off, play, pause, and skip tracks, or use the M-button to instantly access presets, their signature controls get you straight there.

Charging Bank

Power up your playlists and use Kilburn III to charge your phone whenever it needs a boost. Just plug in, and let your speaker do the rest.
