Nokia phones that support HD-voice - X3-02/C3-01, E5, N8, C7, E7, C6-01

“HD voice enables significantly enhanced audio quality on mobile devices calls. It doubles the audio bandwidth available using an industry specified speech codec called Wideband Adaptive Multirate Speech (WB-AMR) which extends audio bandwidth to 50-7000 Hz, compared with today’s narrowband frequency range of 300-3400 Hz. Higher bandwidth means a clear voice experience.
