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.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.
