STronic Vario PRO K+ from the Longlife Vario series offers premium sound quality due to the integrated Knowles Microphone. It lasts up to 180 days in standby mode depending on the selected battery.
This listening device is reliable, easily installed, and used. It has the VOX call-back function, which is also the only command of this GSM Bug. It is small, compact, and easy to hide.
The Vario PRO K+ does not come with a battery, however, it can be connected to an external battery, like the STronic BA-5500 mAh, or to an external 220V/12V power source.
The device itself can be used as a charger for the external battery when connected to the charger cable and adapter head that comes with the accessories. However, it can also be used with an external charger if you wish to.
The miniature high-quality Knowles microphone is a long cable and as such, it can be hidden in a number of places.
