OPPO HA-2 SE Headphone Amplifier and DAC

 

High-resolution USB DAC for Apple/Android/PC/Mac

ESS Sabre32 Reference ES9028-Q2M DAC chip

Mobile power bank for charging your phone


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 Sabre32 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 digital audio 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.
