Yesterday, Best Buy officially announced that it will start carrying the new blue HTC One starting September 15. According to Jeff Gordon, the Senior Global Online Communications Manager at HTC, the “Metallic Blue” One being sold at Best Buy is slightly darker than the “Vivid Blue” that was announced in Europe last week for the HTC One and One Mini.

The HTC One is famous for its incredible front-facing BoomSound speakers, but clearly HTC feels there’s still room for improvement. The Taiwanese company today announced BoomBass, a miniature subwoofer that promises to bring even better sound to your HTC One and One mini.

After being leaked a number of times in recent weeks, the Desire 601 was today made official by HTC. The midrange handset has been designed to provide access to a number of headline HTC features — such as BoomSound, Sense 5, and HTC Zoe — in a slightly smaller, cheaper package.

We’ve already seen HTC’s limited edition Hello Kitty Butterfly S thanks to a leaked promotional poster that was pictured last week — but today the Taiwanese smartphone maker made the handset official. It looks identical to the original Butterfly S, but it has a Hello Kitty face on its back and comes pre-loaded with nine Hello Kitty wallpapers.

Lots of rumors have emerged over the course of the past three weeks, as well as a leaked press render on Twitter, suggesting that HTC is developing a plastic-bodied device similar to the company’s flagship smartphone. And now over the weekend a new tweet has surfaced giving us reason to believe that the device, which has been referred to as ‘Zara’ for the past few weeks, could actually be named the ‘Desire 601’.
