Jabra Pro 9470 wireless headset for telephony u. Dictate in speech recognition

Property me the headset "Jabra Pro 9470" a month ago bought because I changed my computer system from Windows XP to Windows 7 64 bit and I needed a 64-bit driver. Had previously Jabra Jabra 9350. For 9350, built in 2007, there is no 64-bit drivers.
Between 9350 and Jabra Jabra Pro 9470 are to my mind "worlds" differences into something positive. No Hall even with Internet telephony. The headset is very pleasant light and has a excellent sound. I have connected the headset to an ISDN telephone Elmeg CS 410, also with 64-bit drivers for Windows 7 64bit.
The headset can be connected to a landline phone via wireless, with a mobile phone via Bluetooth and via USB to the computer, so I can make calls via landline, mobile phone and computer. Likewise, the headset is super well suited for dictation with speech recognition Dragon 11 and Dragon 12th
The headset thus fulfilled all my wishes with regard to telephony and dictation with speech recognition Dragon NaturallySpeaking 11.5.
