Plantronics Voyager Pro HD Bluetooth Headset (Refurbished) Smart Sensor Technology Making and receiving calls is simpler with Smart Sensor technology in the Voyager PRO HD. The headset knows when you are wearing it so it cleverly routes calls to the headset when it's on your ear and to the handset when it's not. The Voyager PRO HD also has a locking call mechanism when it is not worn to eliminate accidental calling, and you can answer incoming calls simply by putting the headset on your ear--no buttons to press, applications to open or voice commands required.
And if you are listening to music or other audio taking off the headset will automatically pause the stream. The Voyager PRO HD also features enhanced voice alerts that announce remaining talk time, connection status, battery-level, and mute. Smart Sensor technology knows whether to send calls to your mobile phone or your headset (view larger). WindSmart Noise-Canceling Technologies WindSmart technology incorporates enhanced stainless steel windscreens and GORE acoustic vents, as well as an electronic filter within the mic circuitry, making call audio clearer and sound more natural. Use Multipoint One Call at a Time Once you have activated multipoint and paired your two phones, it's easy to answer calls from either phone.
When already on a call, you will hear a ringtone notification of the incoming call from the second paired phone. To answer a second call from the other phone, you must end the current call (tap Call button) so new call automatically answers. If you choose not to answer the second call, it will go to voicemail.
