High-Resolution Audio
Meets Style and Design

The HA-2 is an elegant yet sophisticated portable headphone amplifier with built-in rechargeable battery. It is engineered to enhance music playback from mobile phones and portable music players. Aesthetically, the HA-2 does not look like a typical or generic electronic device. Its genuine leather casing with contrast stitching and beveled aluminum edges are eye-catching and cannot be confused with any other product. Its fit and finish will instill a sense of pride when using the product.

Featuring hybrid class AB amplification and a USB DAC that supports 384 kHz PCM and DSD256, the HA-2 offers high performance digital-to-analog conversion for Apple's iPhone/iPod products, a wide range of Android devices, PC and Mac computers. The HA-2 may be conveniently used to charge mobile devices on-the-go and itself can be efficiently charged in 30 minutes. Headphones, from very sensitive In-Ear Monitors to the most power-hungry Over-the-Ears, can all benefit from the HA-2's excellent performance and powerful amplification.
