The other side of the bar contains controls for power, volume, and Bluetooth connectivity. There's also a line-in/aux jack, mic, and mini-USB port. Zooka automatically switches from Bluetooth to aux input when a device is connected to the aux jack.

The USB port is used for charging Zooka. Battery life on a single charge is about eight hours, although the bar can be used as it's recharging.

Zooka's mic allows the unit to be used as a speaker phone. When paired with a handset, you can answer a phone by pressing Zooka's Bluetooth button. To disconnect from a call, you simply press the button again.

You can reject a call by holding the button in for two to three seconds. Its sound quality as a speakerphone is the equivalent of that produced by a desktop or mobile handset--it's not exceptional, but serviceable. 

A 2.5-inch metal rod that slips conveniently into one end of the unit can be screwed into Zooka's back. That "kick stand" allows devices slotted into the unit to be used in an upright position. The problem with that arrangement, though, is you can't access Zooka's controls, as the edge they're on becomes the bottom of the unit.
