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.

Good enough
Size: 15x6.8, Color: Black
As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.

Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.
