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.

Amazing Jewelry Travel Case
I bought this jewelry case for traveling on a cruise and I absolutely LOVE IT! When I purchased it I didn’t know if it would actually fit all the jewelry I wanted to bring but this box definitely impressed me! It fit all my regular jewelry plus more bc you know us woman love to coordinate with our outfits lol the case/box is sturdy! It didn’t break or even dent throughout my travels. It comes with different pieces to help organize and separate jewelry but it is removable if needed which I had to do bc one of my necklaces is really big. The case fit perfectly in my carry on luggage and didn’t take up much room at all which helped me a lot. I got the black case and I just love how simple and sleek it looks. This is definitely a must have if you need to travel with jewelry and are concerned about things getting damaged, this case keeps them safe and it’s definitely a great value for your money!

So cutie
Color: Cloud White, Material Type: Paper, PU
This is a bit large for a travel size jewelry box lol I really thought it was going to be a bit smaller than what it was. I can see why some of the ladies in the comments are saying they’re using it as their main jewelry box since they don’t have much jewelry for a standard sized jewelry box. With that being said, it’s cute and CAN be small enough for travel. It fits a lot and I got this one in particular bc I like that it has a bigger lower compartment for larger pieces. It’s a nice quality travel jewelry box. It’ll fit my needs. But if you have a knack for packing small and you value space. I’d say skip on this one or do due diligence to double check the measurements to see if it’s something you’re okay with packing.
