A MUCH cheaper route than the Comrex (although I have no experience with the Opal) for regular guests is to use the Yeti USB mic. I used a package deal like this because I was dealing with several sets of guests and only wanted to write one set of instructions.

There are other USB mics out there, just make sure the headphones connect directly to the mic, not the computer to avoid latency issues:

I sent it directly to the guests (it was for a series I engineered) and you can hear a short sample here: http://17biblicalprinciplesofsuccess.org/rick-a-whitted/ 

The first voice you hear is mine, in the local studio in Pennsylvania, the second, Rick's is coming to me through the internet from Florida, while I was also recording the other two guests simultaneously, one in Arizona and the other in Ohio and the program host in Arkansas. You would be hard pressed to know that Rick (or any of the others for that matter) was not in the studio with me!

The Chrome based website it passes through is called Source Connect Now https://now.source-elements.com/#!/  which is FREE.  I can send you the instruction sheet I used if you would like. I have found about 10 mbps down and 5mbps up seems to cover the bandwidth needed, and I have also done it from a hotspot on my phone.

I have also used Google Hangouts with some success, but not the same quality as the methods above because of some of the reasons you mentioned (mic, cell phone quality, etc.) You can hear some of those here. https://soundcloud.com/wake-up-right

Any questions, feel free to call!

I have an old Logitek usb headset that sounds decent. It’s no RE-20, but it works, and it positions the mic so that plosives are avoided.


Have you tried Linphone? It’s a free app and it has worked very well connecting to our Comrex Access. There are apps for smart phones, Windows, Apple and Linux. People you connect with would need to have explicit setup instructions.

I'm considering ordering one of the new Comrex Opal's for use with guests of our programs who are currently only available by phone. It works through a web interface and is compatible with computers as well as Android and iOS devices.  I'm wondering if a USB headset connected to a computer might yield better results than connecting via smartphone and just using the phone's built-in mic.


My thought was to buy several decent USB headsets and send them to booked guests in advance of our interviews.  After the interview, they would return them to us and we'd send them out to the next guest.  For regular guests, we might go with a more robust setup, but I'm trying to keep this as simple as possible.  Plug 'n' Play is ideal.


Does anyone have any recommendations for good USB headsets?  I'm not aware of any "broadcast" headsets that have a direct USB connection, but perhaps some of the gaming sets would sound reasonable.


My concern with the mics built into smartphones is that smartphones differ greatly AND the way people treat their smartphones differs greatly.  We produce a number of talkshows that have callers and the sound of most mobile phones is pretty bad these days.  I'm not sure if it's the build of the phone, or the fact that the caller dropped it in the sink while washing dishes.  Either way, using the built in mic with the Opal might just give us a higher quality garbled sound.


FYI, the Comrex Opal uses the Opus algorithm at 48kbps.  I've requested a demo unit and one of the things I'll be testing is cascading effect.  I did some pretty extensive tests awhile back with Luci Live and Luci Studio.  It sounds very good provided you can maintain a good data connection.  Unfortunately, it's pretty pricey.  Luci Live Lite is decent and cheap or free, but limited to G.722.  I think the Opal should sound better.

I have tried Linphone and it works well most of the time. Finicky to set up. You do not need to register with a sip server to connect. user@123.456.789.10 works fine.
