no lip-sync delay

BluePack, along with a professional video camera app, lets you transmit or record broadcast worthy interviews while placing the mic in the subject's hand for improved audio quality. Connect headphones or an IFB earpiece to monitor the mic signal, as well as return from the station or playback of the video. Alternatively, a boom operator can use BluePack to monitor the mic signal as the Bluetooth wireless audio gets transmitted to the phone or tablet.

*HD Voice: While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD Voice calls offer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives voice a more natural sound, while the additional upper octave dramatically improves speech clarity and intelligibility.

*Wireless HD Calls: To take advantage of this extended bandwidth, both phones on the call must support HD Voice, and both phones must be on the same carrier, in coverage areas that support HD Voice.
