The black and red V-Moda Vamp Headphone Amp / Battery Pack for iPhone 4/4S provides enhanced audiophile-grade sound for your iPhone 4 or 4S, additional battery life and sturdy protection. V-Moda's Vamp takes the digital output from your phone and uses a dedicated hi-fi digital-to-analog converter (DAC) and amplifier for pure, powerful sound. Vamp features a V-Moda eQualizer (VQ) function that provides 3D sound and accentuation for various musical tastes. Vamp also includes a digital to digital conversion function that outputs digital sound data from the iPhone as optical audio (S/PDIF). While inside the case your phone is wrapped in aircraft-grade brushed metal and shock-absorbing silicone for superior go-anywhere protection.
