Sprint has announced a special edition HTC One M8 that targets music lovers. The Harman Kardon edition HTC One M8 includes a set of Harman Kardon headphones, a custom color scheme and tuned audio for better sounding playback.

In a press release on the matter, Sprint outlines two key techniques uses to improve audio quality. The first is an application called Clari-Fi that restores and rebuilds music fidelity lost during audio compression. The wireless carrier claims the app yields richer, deeper and clearer sound quality for compressed digital music.

The handset also touts lossless HD audio music reproduction via a 24bit/192kHz DAC that delivers roughly six times the information of compact disc music and 60 times the information of an MP3 or streaming music source when playing high-res digital (FLAC) downloads.

The Harman Kardon edition further includes a set of AE-S in-ear headphones with extended bass response – a $149 retail value. Reviews of the headphones cite quality audio performance with healthy bass response although the remote buttons aren't well defined and the cable is somewhat rigid.

Sprint is also treating Framily plan members to six month of free Spotify Premium service so long as they have an Android phone, iPhone or Windows 8/8.1 handset. Those not on a Framily plan can try the service free of charge for three months.

The Harman Kardon HTC One M8 will be available starting May 9.
