The HA-2 is an elegant portable headphone amplifier that has been engineered to enhance music playback from mobile phones and portable music players. The HA-2 has a genuine leather casing with contrast stitching and beveled aluminum edges that are eye-catching & sophisticated.

Featuring hybrid class AB amplification and a USB DAC that supports 384 kHz PCM and DSD256, the HA-2 offers high performance digital-to-analog conversion for Apple’s iPhone/iPod products, a wide range of Android devices, PC and Mac computers. The HA-2 may be conveniently used to charge mobile devices on-the-go and itself can be efficiently charged in 30 minutes. Headphones, from very sensitive In-Ear Monitors to the most power-hungry over ears, can all benefit from the HA-2’s excellent performance and powerful amplification.

  • Hybrid Class AB Amplifier

    The HA-2's power amplification circuit for headphones is Class AB built with integrated circuits (ICs) and discrete transistors. The discrete transistor output stage uses hand-picked and matched parts. 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 Sabre 32 Reference DAC

    The ES9018-K2M DAC chip used in the HA-2 is the mobile version of the ES9018S used in Oppo's award-winning HA-1 desktop headphone amplifier. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE 32 Reference DAC delivers an unprecedented performance for mobile applications.

    Bass Boost 

    For those who like a bit more punch and impact with their music, the HA-2 offers a Bass Boost function. With Bass Boost off, the HA-2 delivers very flat frequency response; with Bass Boost on, the HA-2 adds force and impact to the sub-bass region without muddling the important mid- to high-frequency bands.

    Asynchronous USB DAC

    By bypassing the smartphone's built-in DAC and headphone amplification circuit that are often cost-constrained, the HA-2 turns a smartphone into a high performance digital audio player. The asynchronous USB DAC input of the HA-2 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).

    Compatible with Android

    The HA-2’s micro-USB input port works with Android devices that support USB OTG (USB On-The-Go) and USB Audio Class. A special USB OTG cable is supplied with the HA-2 to facilitate the connection. When used with a compatible Android device, the HA-2 can support the device's built-in music app, tones and notifications. Additionally, a high-resolution music playback app can use the HA-2 as its external DAC to play lossless PCM and DSD audio files.

    Made For iPod, iPhone and iPad

    The HA-1 passes Apple's "MFi" certification and is compatibile with the latest iPod, iPhone and iPad so that it can be used as the digital audio output accessory of these devices. By tapping directly into the digital audio signal of these devices and converting the audio to analog using the high performance SABRE 32 Reference DAC, music from your favorite portable device will sound brilliant. Furthermore, for users with high-resolution music playback apps, the HA-2 does not require the use of a Camera Connection Kit (CCK). The data cables that come with your Apple device or the supplied Lightning cable is sufficient.

    Rapid Charging & 13 Hour Battery Life

    The HA-2 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 approximately 30 minutes. It only takes about 90 minutes to fully charge the battery. A quick charge gives the HA-2 hours of operation time. The HA-1 provides 13 hours of battery for analog source via Audio-in & around 7 hours for digital sources via USB.

    " For £250, you’ll struggle to find better detail or dynamics from a headphone amp and USB DAC."

    " An added benefit is the form factor will greatly appeal to Apple and Android users who will want to take advantage of the OTG and direct lightning connectivity not to mention the power bank option which I guess is a bit of “keeping up with the Jones” there days but still a relative useful feature if in a pinch. Placing a modern day smartphone on top of the HA-2 feels very normal and logical. It will also make considerable inroads to those who might have chosen other audiophile convergence devices like the FiiO E18 and the Creative E5 which can’t hold a candle to the HA-2 in terms of audio quality all-round attractiveness physically."
