I am having problems with my Jabra 930 Pro. It works fine with Skype. However, when I select it as my source DPI 15 in an existing profile or create a completely new profile with it, I cannot get past the microphone "set up" for it. The visual indicator for sound stays on zero and I get a return with "microphone sound is too low." Or something like that.

Weirdly enough, if I use Skype and call a company with a never ending phone tree while simultaneously opening up DPI 15 and choosing the Jabra as my source, it works fine. The Skype call will go on like regular for for 5+ minutes, giving me plenty of time to completely set up the microphone and Dragon and dictate the Gettysburg address in anything, e.g., DragonPad.

Does anyone have any idea what the problem is?

PS: I'm running Windows 10 Pro completely updated on a Intel I7-6700k, 16 GB RAM floortop PC. I have approximately 8 Bluetooth headsets that have been paired and another 4 or 5 Bluetooth keyboards and mice. Sound can actually come from 3 places: (1) my Asus Z170 mainboard sound, (2) my Nvidia video card, (3) and a Sound Blaster AE5 hi-ohm sound card for hi-ohm headphones. Nothing is plugged into the motherboard sound outs. This sounds like a lot, but it's worked fine for many years.

Since you have several Bluetooth microphones, can you check to see if any of your other Bluetooth microphones work properly in Dragon?

Hi Linus, sorry for the delay in getting back to you. I threw some money at the problem, did a lot of googling, and a ton of troubleshooting and I think I resolved the problem. By the way, despite what my profile may say I've been around here for at least 20 years. I talked to you in the late 90s, or thereabouts, when you resolved my Dragon problems when I was under the gun getting a brief out. BTW, thanks again for that! :-)


Yes, I do own a lot of Bluetooth headsets in a wide array of form factors including one pair that fit in your ear like women's plastic earrings. They all have microphones. They all will show up as potential sources in DPI when they are connected. When you connect a Bluetooth headset and click on the speaker in the system tray you will see a list of everything that's connected. Bluetooth devices have at least 2 entries, [name of device] (Stereo) and [name of device] (+ Hands-Free AG Audio).


What appears to be happening is within ordinary Bluetooth dongle and an ordinary set of stereo Bluetooth headphones with one or more little holes in the front of the cups for the microphones will support ordinary "high-quality" stereo for music or mono hands-free AG audio. This latter option will immediately drop the quality of the music to monophonic and insert some kind of playback frequency altering algorithm that makes the music sound terrible, literally hurting your ears. They do not work very well for speech recognition.


Before, I assumed that I wanted a DECT mono microphone/headset speaker. That was before I trialed a couple of noise canceling microphone headsets. (In fact, the only 2 I could find I purchased. They are the AfterShokz OpenComm UC Bone Conduction Bluetooth Stereo Computer Headset with Loop100 and the Bluetooth Headset V5.1, Wireless Headset with Noise Canceling Microphone, 40 Hrs Work Time Office Headset with Bluetooth Dongle & Charging Base, AptX HD On-Ear Headphones with Mute Button for $75 by Soothielec. This latter microphone is basically by a no-name Chinese company. IMHO their implementation of their noise canceling microphone (not headset) is as good or better than Shokz. Parenthetically, their implementation of AptX is the best I've heard. The problem is there are not many AptX PC dongles the last I checked. If you want me to send you a pair Soothielecs to review, DM me.


Interestingly, if you Google the question, "does Windows 10 support more than one Bluetooth dongle" you will get surprising unanimity and an unambiguous no. They will conflict. Purportedly, you can see the conflict in device manager. However both the Shokz and Soothitelec seem use the same trick, a AB Bluetooth dongle is that seems to be "bound to" their respective devices out of the box. In that sense they function similarly to DECT. So despite the fact that Windows does not support more than one Bluetooth dongle, I'm finding a problem with the 3 that I have plugged into my PC — one ordinary and 2 for the microphone headsets mentioned above. And one more additional RF to my keyboard.


Coming back around to DECT I googled around for a DECT office headset that supported microphone noise canceling. I did find a $500 Jabra Evolve 85 that had 10 microphones on its boom for beamforming, but no true microphone ANC. The headset was ANC, but who really cares about the headset when  looking for is super accurate microphone for Dragon. I am sold on noise canceling microphones.


I apologize for the length of this, I was rather in a hurry.
