Burlingame, CA, May 4, 2015High Resolution Technologies (HRT) today announced it is now shipping its new nano series dSp and i-dSp digital Sound processors, two accessories that provide significantly improved headphone sound quality for smartphones, tablets and portable devices.

The dSp will also operate with compatible Apple iOS 6 (and newer) devices with a 30-pin connector when used with the 30-pin to USB-A adapter from the Apple iPad Camera Connection Kit.

“With the dSp and i-dSp you’ll now be able to hear your favorite headphones and music at their best from accessories that are attractively priced,” said Mike Hobson, Chief Executive Officer at HRT. “Just plug one in between your headphones and smartphone or listening device to enjoy a significantly better listening experience from streaming audio, high-resolution audio and most any other format.”

The nano series is designed for those who use their phones, tablets, laptops and other portable devices as their primary listening and viewing platforms and who seek the best-possible headphone sound for music, video and gaming with improved resolution, spatiality, dynamics and heightened realism.

The HRT dSp and i-dSp are compatible with all audio formats supported by portable devices running Android, Windows, Apple iOS and OSX, thanks to their UAC (USB Audio Class) interface.
