For pristine stereo sound, the P7700 incorporates a built-in stereo microphone, an external microphone input, a HDMI mini connector and HDMI-CEC support.
There's a full-size SD card reader and a standard 3.5mm headphone jack (with mic support) on the left, plus the power input, HDMI output, USB 2.0 port, USB 3.0 connector and SIM slot (currently unused) in back.
