Introduction
Thank you for choosing the OPPO HA-2(SE) portable
headphone amplifier and USB DAC. The HA-2(SE) draws
upon the success of the HA-1 desktop headphone amplifier
and is optimized for portable use. Featuring a hybrid class AB
amplifier and a USB DAC supporting 384 kHz PCM and
DSD256, the HA-2(SE) offers high performance digital-to-
analog conversion for both Apple’s iPhone/iPod, Android
devices, PC and Mac computers. A 3.5 mm input works with
the remaining portable music players that do not have a USB-
compatible digital output. Convenience features such as
VOOC rapid charging and a mobile device power bank make
the HA-2(SE) a true companion for music on the go.
