Product Description

Oppo HA-2SE is a transportable headphone amplifier supporting high resolution music and featuring USB DAC for Apple and Android devices along with PC and Mac. It is an upgrade to the award winning HA2 which accumulated high critical acclaim.

What's New?

Owing to the success of the HA2, Oppo developed the HA-2SE with the mentality of only making minimal changes to update the amplifier and fix some previous concerns but always retaining the same excellent design, engineering and performance.

To this end, the amplifier has been fitted with the most recent ES9028-Q2M Sabre32 Reference DAC chip in place of the ES9019-K3M that was used in the original model. The noise floor was dropped significantly lower while the signal to noise ration was substantially intensified reducing hissing and white noise to make the amp suitable for use with sensitive IEMs. 

High-Res & Stylish

A stylish yet understated design, HA-2SE utilises an integrated rechargeable battery allowing you to carry it wherever you go. It was invented to boost music playback from phones and portable audio players. The eye-catching amp features a real leather case with a contrast seam and chamfered aluminium edges. Containing cross class AB augmentation and a USB DAC that caters for PCM and DSD, HA-2SE is a high performance DAC for Apple’s iOS devices, many Android devices as well as PC and Mac computers.

ESS Sabre32 ES9028-Q2M

Equipped with the ESS original 32-bit Hyperstream DAC construction and TDJE, the Sabre32 Reference ES9028-Q2M DAC produces a record performance for mobile applications. HA-2SE converts your smartphone into a great performance digital player. The asynchronous USB DAC input functions with PC or MACs to swap the integral sound card and enables high-res audio reproduction with PCM up to 32-bit and DSD up to 12MHz.

Music on the Go

Headphones, beginning with extremely sensitive In-Ear Monitors to the most megalomaniac over-ears can all profit from the HA-2SE’s outstanding presentation and prevailing amplification. The power amplification topology for the headsets is Class A and B made with integrated circuits (ICs) and isolated transistors. The crop transistors are partial to activate in their most direct choice for the serious small signal, and transport their complete potential when power is essential.

Clean Signal Path

The HA-2SE offers a spotless signal path for the acoustics by evading re-digitisation of the audio signal for volume tuning or bass lift. The HA-2SE uses original VOOC fast charging skill from OPPO. Through the included rapid charger the inner battery can be speedily and securely charged to 70% in 30 minutes.

Build Quality

HA-2SE is encased in an aluminium housing wrapped in authentic leather. The HA-2SE corresponds well in the pocket of an urban Millennial or on the desk of a corporate executive. The HA-2SE is well-suited for the cutting edge iPod, iPhone, iPad and android devices that support USB On-The-Go and Audio Class. Music from your preferred portable device will perform at its best.

Two Gain Settings

HA-2SE has twin gain level settings for best headphone pairing, the High Gain mode for powering huge and demanding headphones and the Low Gain mode for subtle In-Ear Monitor category earphones. The HA-2SE has a Bass Boost function for enthusiasts who want greater power and impact in their music.

Mobile Power Bank

HA-2SE also works as an exterior battery pack to charge your mobile phone. HA-2SE features a 3.5mm music input to handle portable audio players that do not have a USB digital output. Though the HA-2SE is custom with one of its USB numeral inputs, the 3.5 mm jack works as Line output for the USB DAC

Press Reviews

  • 'Oppo makes minor advancements to its 2015 Award-winning DAC, which remains as pertinent as ever in a burgeoning market. For wide compatibility, clear, agile and detailed sound, more open treble, tighter bass, practical design.' (What Hi-Fi Magazine October 2016)

  • 'This may not sound particularly revolutionary, but it shines through in the performance. Thankfully, the original’s dynamic, articulate and detailed sound still provides the solid foundations of the HA-2 SE’s presentation.' (What Hi-Fi Magazine October 2016)

  • 'They’re direct too, gushing over the top of the instrumentals with stark clarity and focus. The jazz arrangement is rhythmically sound, the Oppo breezing through the track with energy and crisp timing, revealing its progressive giddiness. With the lower frequencies, this DAC balances depth with suppleness well... The more versatile Oppo has more features though, making it one of the budget DAC market’s most important offerings.' (What Hi-Fi Magazine October 2016)

  • 'it is good to note that sonically, the new model makes some useful gains over the old one. With an original HA-2 running in parallel connected to a Lenovo ThinkPad, the single biggest change is the drop in the noise floor.' (Hi-Fi Choice Magazine February 2017)

  • 'What (HA-2SE) does ensure is that an already excellent product has improved even more in expectation of the portable headphone and DAC market becoming a lot more significant in the year ahead... the HA-2 SE is a very desirable add-on device at a highly tempting price.' (Hi-Fi Choice Magazine February 2017)
