The UE Boom comes in a interesting, yet not surprising packaging. The speaker is bundled in a tube-shaped hard-box, which I guess, can also serve as a travel-case, since its made from plastic and aluminium. Opening the case, you get the speaker.
Two small disk-shaped cases contain the flat lime green micro-USB cable and adapter, as well as a lot of reading material. It certainly could be better, but it does the job.
The speaker itself has a soft-to-the-touch rubberized finish, and the model we got, being black & dark-grey, had a tendency of getting smudged quite often. Yet, due to the material in use, it can wiped off with a damp cloth, and there won't be any issues.
There are volume controls on the rubberized side, though it's far easier to just use the smart-device as a remote. Of course, as you might expect, the speaker has speakerphone capabilities also integrated in it.
If you would be able to remove the speaker cover (which alas is not detachable), you would find 2x1.5-inch drivers and 2-inch passive radiators. As such, the Boom is designed to produce 360-degree sound, sounding almost the same whether you are standing in front or behind it.
Since the speaker itself is water-resistant, you could use it in the rain, or in the shower (though don't keep it under the shower stream for too long). On the end of the speaker, where the USB and 3.5mm audio input is located (which are also covered by rubber caps), there's also a hook, allowing you to clip the speaker to the backpack (for example).
On the end of the speaker, where the USB and audio input are located, there's also a hook, to clip the speaker on to a backpack. Unscrewing the hook reveals a threaded tripod mount.
What I will say I found odd is the rechargeable cable, which is a very thick, wide and lime-green micro-USB cable, which can be strapped to an AC adapter included in the package.
