Sprint sends out invitations for unveiling of HD Voice on April 29th11
The HD Voice feature eliminates background noise on phone calls and also does away with the tinny background noise that affects some phone calls. While quite a few Sprint branded handsets are now compatible with HD Voice, the carrier plans on sending out a software update that will allow more of Sprint's smartphone lineup to be compatible with the feature. The names of those handsets that will be receiving the update are expected to be announced in July, just before the update is sent out OTA. Also in July, Sprint has said that it would flip the switch to turn the HD Voice feature on nationwide.
The phones that currently are compatible with HD Voice include: BlackBerry Q10, Google Nexus 5, HTC 8XT, HTC EVO 4G LTE, HTC One, HTC One max, Apple iPhone 5c, Apple iPhone 5s, Kyocera Hydro EDGE, Kyocera Torque, LG G2, LG Optimus F3, LG Optimus G, Motorola Moto X, Samsung ATIV S Neo, Samsung Galaxy Mega 6.3, Samsung GALAXY Note II, Samsung Galaxy Note 3, Samsung Galaxy S4, Samsung Galaxy S4 mini, Samsung Galaxy S III, Sprint Flash, Sprint Force and the Sprint Vital.
