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.
