I’m selling an unused OPPO HA-2SE Portable Headphone Amplifier, featuring the high-performance ESS Sabre32 ES9028-Q2M DAC chip for superior audio quality (no box).

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.
