The HA-2SE 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-2SE does not look like a typical or generic electronic device. It features a Hybrid Class AB Amplifier built with integrated circuits (ICs) and discrete transistors. It has a clean signal path for there is no Digital Signal Processor in the HA-2SE. It also features the latest flagship mobile DAC developed by ESS Technology which is the ES9028-Q2M. By bypassing the smartphone’s built-in DAC and headphone amplification circuit that are often cost-constrained, the HA-2SE turns a smartphone into a high performance digital audio player. The asynchronous USB DAC input of the HA-2SE also works with PC and Mac computers to replace the built-in sound card and support high-resolution audio playback with PCM up to 384 kHz 32-bit and DSD up to 12 MHz (DSD256). The HA-2SE may also be conveniently used to charge mobile devices on-the-go and it also can be efficiently recharged in 30 minutes.
