Hybrid Class AB Amplifier

The HA-2SE's power amplification circuit for the headphones is Class AB built with integrated circuits (ICs) and discrete transistors. The output transistors are biased to operate in their most linear range for the critical small signal, and deliver their full potential when power is required.

Ess Saber32 Reference DAC

With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented performance for mobile applications.

Asynchronous USB DAC

HA-2SE turns a smartphone into a high performance digita laudio player. The asynchronous USB DAC input 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).

Clean Signal Path

The HA-2SE provides a clean signal path for the audio by avoiding re-digitising the audio signal for volume adjustment or bass boost.

Rapid Charging

The HA-2SE features patented VOOC rapid charging technology from OPPO. Using the supplied rapid charger the internal battery can be quickly and safely charged to 70% capacity in about 30 minutes.
