The AmpCase Headphone Amplifier For iPhone 4 from Alesis uses the iPhone's 30-pin dock connector to transmit high quality audio with a wider dynamic range than you would get via the standard headphone jack. The case features a convenient volume control wheel as well as a mini USB jack so you can charge your iPhone without removing it from the AmpCase. Thanks to its slim profile, the AmpCase adds little bulk to your iPhone so you can keep it attached at all times.
High Quality Sound
Your premium headphones may look great, but they'll only sound as good as what they're plugged into. AmpCase makes headphones sound incredible. You'll finally experience your music like it was intended to be heard. AmpCase receives a direct injection of unadulterated, noise-free audio directly from your iPhone's 30-pin dock connector. This unrestricted and uncolored signal enables you to enjoy the full dynamic range of any song. Alesis DSP technology pushes the best output to your headphones, with improved presence, punch and power. The AmpCase's linear power amplifier drives signal-thirsty headphones with authority
Form-Fitted Fashion
Enclosing the iPhone completely, AmpCase includes contoured cutouts for all of your iPhone's controls. A large wheel on the side gives you precise, continuous volume control, and a mini USB jack lets you charge your iPhone without removing it.
