Ultimate Ears is at it again, updating the last straggler in its line of Bluetooth speakers to get them all on the same page in terms of build and software. A few months ago, the company revamped its entry level offering and today Ultimate Ears is announcing the UE Boom 2. This is the mid-level speaker in the UE lineup and although the changes may be hard to notice at first glance, they're significant enough to warrant a second look. It sports a fresh set of colors and a tighter fabric mesh that contributes to its new IPX7 waterproof rating. The internals have been reworked to improve Bluetooth range, sound quality and offer a few special features. The UE Boom 2 is available today on the Ultimate Ears website, with Apple's online store following close behind. You can pick one up for the same $199 price as the original UE Boom (it's £170 in the UK), but you'll be getting a good deal more under the hood.
