Among the new Windows Phone 7 devices showcased yesterday we also found the interestingly designed HTC 7 Surround. This multimedia-oriented smartphone comes with an original design, that includes a sliding speaker with huge potential for turning any get together into a party.

It also supports virtual surround sound with Dolby Mobile and SRS WOW HD. There’s also a surround sound button on board, if you want to take the party up a notch. Also, HTC 7 Surround uses a Sound Enhancer app for the best equalizer effects and mixing bass, treble and vocal levels. Here’s the specs list for this beauty:
