OPPO Introduces HA-2SE Portable Headphone Amplifier and DAC


Award-Winning HA-2 Gets a Performance Boost

Singapore – November 24, 2016 – Continuing the pursuit of innovation and value for customers, OPPO Digital (www.oppodigital.com) today introduces an updated version of the award-winning HA-2 portable headphone amplifier and DAC, HA-2SE.


Aesthetically the HA-2SE continues the HA-2’s elegant style and design - genuine leather casing with contrast stitching and beveled aluminum edges. Inside, the digital-to-analog converter (DAC) chip is upgraded to ES9028Q2M, top-of-the-line from ESS Technology’s SABRE32 Reference series for portable designs. The headphone amplifier is further optimized for very sensitive In-Ear Monitors, with lower noise floor and higher signal-to-noise ratio over the HA-2.


OPPO HA-2SE is engineered to enhance music playback from mobile phones and portable music players. Featuring hybrid class AB amplification and a USB DAC, the HA-2SE offers high performance digital-to-analog conversion for Apple’s iPhone/iPod products, a wide range of Android devices, PC and Mac computers. Equipped with a 3000mAh internal battery and OPPO’s patented safe rapid charging technology, The HA-2SE may be conveniently used to charge mobile devices on-the-go and itself can be efficiently charged in 30 minutes.

Key features of the HA-2SE include:

  • Ultra-slim Design - Stacking the HA-2SE on top of some smartphone models is often still thinner than other portable headphone amplifier models alone.
  • ESS Sabre32 Reference DAC - ES9028Q2M DAC chip delivers high-resolution performance with extremely low noise and distortion.
  • High-Resolution Audio – The HA-2 supports PCM audio up to 384 kHz / 32-bit, DSD audio up to 12 MHz (DSD256 or DSD4x). No Camera Connection Kit required for high-resolution playback from iOS devices.
  • Multiple Devices Support –The HA-2SE supports multiple device types for digital-to-analog conversion via USB: iPod / iPhone / iPad, smartphones with USB OTG feature, PC and Mac computers.
  • Rapid Charging – The HA-2SE’s internal battery can be quickly charged in about 30 minutes with the patented rapid charger.
  • Mobile Power Bank - The HA-2SE functions as an external battery pack to charge mobile devices.

The HA-2SE is a very mobile-centric portable headphone amplifier and DAC that pairs exceptionally well with iOS and Android devices. It works especially well with Apple’s newly released iPhone 7 and iPhone 7 Plus. Being a “Made for iPhone” certified device and coming with a Lightning cable included, the HA-2SE can charge the iPhone and play music at the same time. Its high-end DAC and high output amplifier can provide a significant improvement in sound quality and drive a much wider variety of headphones than the Lightning-to-3.5mm adapter that comes with the new iPhone. When used with the right apps, the HA-2SE supports bit-perfect playback of high resolution music, exceeding the 48 kHz sample rate limitation of using the phone’s built-in headphone output or headphone adapter.

In addition to the USB DAC inputs, the HA-2SE provides a 3.5 mm line-in jack for portable music players that do not have a USB-compatible digital output. The same jack doubles as line-out when the HA-2SE is used as a DAC. The headphone amplifier has two gain level settings. The High Gain mode is capable of driving large power-hungry headphones, delivering up to 300 mW into 16-Ohm headphones. The Low Gain mode is intended for sensitive In-Ear Monitor type earphones. For users who like a bit more punch and impact with their music, the HA-2SE offers a Bass Boost function that is implemented purely with analog audio circuits.

With its excellent sound quality, elegant style and mobile-friendly features, OPPO HA-2SE headphone amplifier is a great companion to any smartphone or portable music player. Priced at S$479, the HA-2SE can be ordered from OPPO Digital’s web site or resellers.

The product will be available for hands-on at the Sound & Sight Exhibition 2016 at the Parkroyal on Kitchener Road, Emerald Ballroom Room 1A from 25-27 November 2016.
