Turn Your Portable Device Into a High-Res Music Hub With the Oppo HA-2SE Portable Headphone Amp and USB DAC: Ultra-Slim Size, Premium Looks, ESS SABRE32 DAC, 384k PCM and DSD256
Take one look at the high-performance Oppo HA-2SE portable headphone amplifier/USB DAC and you'll immediately wish all electronics looked so good. You'll also wonder why they all didn't sound as great while asking yourself how you've lived without it until now. Designed for today's mobile lifestyle and more stylish than even the most state-of-the-art smartphones, the premium-mobility and USB OTG-compatible HA-2SE looks like it comes straight out of a James Bond movie. With genuine leather casing, contrast stitching, and beveled aluminum edges, the uber-slim HA-2SE is a minuscule half-inch deep but packs a mean punch. This compact marvel turns any smartphone or tablet into a high-res music hub. Hybrid Class AB amplification and an asynchronous, low-noise ESS Sabre32 Reference USB DAC that supports both 384kHz PCM and DSD256 make it ideal for high-resolution listening with Apple iPhone/iPods as well as Android products, PCs, and Macs.
And the award-winning HA-2SE is always ready for on-the-go use. An internal battery can be rapidly charged to 70% capacity in 30 minutes, and HA-2SE performs double duty by functioning as an external charger for your favorite mobile devices. Two gain-level settings allow HA-2SE to drive all headphone types, while two volume-control stages supply customized control solve any disparity issues between using in-ear monitors and full-sized ‘phones. Completely bypassing DSP for superior sonics, an analog volume control knob teams with the internal DAC-mapped volume-control commands to deliver volume signals of your desire without ever losing resolution or causing truncation.

Hybrid Class AB Amplifier and ESS SABRE32 Reference DAC
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. With the ESS-patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers incredible performance for mobile applications.
Asynchronous USB DAC Plays Up to 32-Bit/384kHz PCM and DSD256
HA-2SE turns smartphones 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 up to 32-bit/384kHz PCM and DSD256.
Stellar Signal Path Combined With Rapid Charging Abilities
HA-2SE provides a clean signal path for the audio by avoiding re-digitizing the audio signal for volume adjustment or bass boost. Patented VOOC rapid charging technology uses the supplied rapid charger so the internal battery can be quickly and safely charged to 70% capacity in about 30 minutes. HA-2SE functions as an external battery pack to charge your mobile device. You can ditch the bulky spare battery pack and carry just HA-2SE with you mobile phone.
Executive-Level Build Quality and Detailing
Housed in an aluminium chassis wrapped in genuine leather, HA2-SE features bevelled metal edges and contrast stitching on the leather. It fits equally well in the pocket of an urban millennial or on the desk of a business CEO.
Tailor-Made for iPad, iPhone, iPod, and Compatible with Android
HA-2SE is both compatible with the latest iPod, iPhone, iPad and Android devices that support USB OTG (USB On-The-Go) and USB Audio Class. Music from your favorite portable device will sound its best.
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 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.
HA-2SE offers a Bass Boost function for those who like a bit more punch and impact with their music.
