Oppo HA2 SE HA-2 SE Headphone Amplifier/DAC is a significant upgrade from the already excellent original!

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.

Its genuine leather casing with contrast stitching and bevelled aluminium edges are eye-catching. And it is conveniently used to charge mobile devices on-the-go and itself can be efficiently charged in 30 minutes.

High-resolution USB DAC for Apple/Android/PC/Mac - ESS Sabre32 Reference ES9028-Q2M DAC chip

Featuring hybrid class AB amplification and a USB DAC that supports 384 kHz PCM and DSD256, the HA-2SE offers high performance digital-to-analogue conversion for Apple’s iPhone/iPod products, a wide range of Android devices, PC and Mac computers.

Audio-in and Line-out

The HA-2SE has a 3.5 mm Audio-in port to support portable music players that do not have a USB-compatible digital output. While the HA-2SE is used with one of its USB digital input ports, the 3.5 mm jack acts as Line-Out for the USB DAC.

Two Gain Settings

The HA-2SE offers two gain level settings for optimal headphone matching, the High Gain mode for driving large power-hungry headphones and the Low Gain mode for sensitive In-Ear Monitor type earphones.

Bass Boost

The HA-2SE offers a Bass Boost function for those who like a bit more punch and impact with their music.
