Product Description

High-Resolution Audio
Meets Style and Design

The 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. Aesthetically, the HA-2SE does not look like a typical or generic electronic device. Its genuine leather casing with contrast stitching and beveled aluminium edges are eye-catching and cannot be confused with any other product. Its fit and finish will instill a sense of pride when using the product.

Featuring hybrid class AB amplification and a USB DAC that supports 384 kHz PCM and DSD256, 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. The HA-2SE 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-the-Ears, can all benefit from the HA-2SE’s excellent performance and powerful amplification.

Quality and Convenience for the Mobile Generation

With smartphone use increasing all the time, users are often carrying a device that is capable of storing high quality audio files. The HA-2SE is a very mobile-centric portable headphone amplifier and DAC that pairs exceptionally well with iOS and Android devices, and it can offer a significant improvement in sound quality over the amplification and DAC available in the mobile device itself, without adding excessive bulk and weight so as to make the combination inconvenient. Other mobile-friendly features such as rapid charging and mobile device power bank make the HA-2SE a true companion for music on the go.

The HA-2SE offers two USB DAC input ports – one for Apple’s iPhone/iPod, and the other for Android devices, PC and Mac computers. A 3.5 mm input works with the remaining portable music players that do not have a USB-compatible digital output. There are 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. In addition to the two gain levels, the HA-2SE offers two stages of volume control to precisely dial the desired output volume and to resolve the volume disparity issues between using In-Ear Monitors and full-size headphones. By mapping USB volume control commands to the Sabre DAC chip’s internal digital volume control, users can adjust the signal volume using the playback app or software without losing audio resolution or causing bit truncation. The HA-2SE’s analog volume control knob can then be used to further adjust for a comfortable listening level. 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.

* High-resolution audio playback from iOS and Android devices may require additional playback apps.
