If you’re an audiophile, then you’re probably not too thrilled with the audio output from most smartphones. This gadget kicks things it up a notch by transforming your phone into a mobile hi-fi system.
The V-MODA Vamp Verza case takes its cues from the original Vamp for iPhone 4/4S and includes a 150mW × 2 headphone amplifier, paired with high quality Burr Brown and AKM digital-to-analog-converters and a 2200 mAh battery pack. The Vamp Verza can be used as a hi-fi USB audio amp, and its additional battery will power your phone for another 7 hours. You can even attach your phone to the face of the Vamp, using the optional Metallo case.
The Vamp Verza comes in matte black, red/black, and white/orange colorways for $598 (USD). The Metallo case is currently available for the iPhone 5 and Samsung Galaxy S III and sells for about $100.
