Vox can be regarded as a slider phone and at the same time as a standard candy-bar, because even closed, the phone has absolutely full functionality and display, as well as a standard numeric keypad and D-Pad with navigational and software keys.

The side-sliding keyboard is spring-assisted which makes sliding easier. It is opened from right to left contrary to Wizard and TYTN, which are opened from left to right. Probably this has been done in order to make the phone slide open easily (one-handed operation) when you take it out of the carrying case.

The full size QWERTY keyboard only has three rows of keys, whereas the PPC phones have four. Because of this each row contains more keys and that makes the size of the keys smaller. Yet, there is some space left between them. The keys are raised and when pressed, they work softly. The blue backlighting is the same for the main characters and for the alternative characters and if you are not used to the keyboard you may look for a certain character for a long time. Confusing the keys is very easy because of the small space between them, hence their close placement.
There are two small service LEDs here to indicate - caps lock - or alternative character - Fn lock (Function). And there are two software buttons, one on each side of the screen, duplicating those on the front panel. When the phone is closed, its front panel is covered in full by the display and the keypad beneath it.

Unlike PPC phones, one can find here full functional numeric keyboard (12 keys), and 6 more navigational keys and 5-way D-pad. The numeric keys are comparatively small, but raised (the lower part is jutted out a little bit more) and can be felt easily. This is the way they are pressed and that is clearly indicated by the tactile response. The situation is almost the same with the D-pad which is not very large either. Our complaint is that the buttons for all directions are hard to press, but the central position button is perfect. On the front panel only the D-pad has no backlighting, the rest of the keypad is backlit in blue (except for answer/reject) and it could be seen clearly in the dark.

The rest of the buttons are placed sideward on the phone and they are much smaller and not backlit. You can find volume rocker and voice commands shortcut on the left side of the phone and camera shortcut/shutter key on the right side of the phone and on the top of the phone you can find the power on/off button which also functions as a shortcut for changing of the profiles and for locking of the keypad like Nokia and Sony Ericsson.

HTC Vox is a small smartphone and compared to PPC phones of the same type (HTC TyTN) the smaller size of the phone is easily noticeable in every aspect. The weight of the phone is perfect for a smartphone. It is a real pleasure to have it in your pocket or in your hand.

For the comfortable usage of the phone helps this awesome to touch, non-slippery rubbery material, which is used for the back panel and the side parts of the phone. The front panel is outlined in chrome metal frame.
Here you can find the color TFT 2.41” display of the device. It features resolution of 320x240 pixels (QVGA 320x240), shows 65 K colors. It has a good contrast and brightness, neutral colours and detailed image.

S710 has two service LEDs, placed in the opening of the speaker on the front panel. The left one indicates the on/off status of the Bluetooth and WiFi and the right one notifies you of the battery and network status of the phone.
On the bottom of the right side of the upper slider is placed microSD (T-Flash) slot for memory cards covered by a piece of rubber. The slot for the Sim card is placed symmetrically on the left side, but if you want to change the card, first you have to turn off the phone. In case you open it without turning off the phone, it will immediately turn off by itself.
