Vox Tube 700 is a Bluetooth-conform and energy-saving mono headset whose elegant case of anodised aluminium is not only a headset but also a USB plug. The Vox Tube 700 can thereby be fitted into any USB port for charging without the use of an interface cable. Noise suppression of the headset is achieved via a built-in microphone and CVC technology and provides best voice quality, even excluding loud background noise. Vox Tube 700 is comfortably operated by one-key control.
