  1. SS

    The MDA220 was purchased for use on a ShoreTEL phone system. I also wished to explore the possibilities of using a less expensive USB headset or earbuds with a USB adapter since I was told by Headsetsdirect that it would probably work. First, I tried two different adapters with the earbuds and it somewhat worked for listening but not with a microphone. I say someone because I first needed to plugin a Plantronics USB headset then swap it with the earbuds. Next, I tried a Logitech USB headset. Again this was problematic so I gave up on this. Finally, I used the MDA220 with a Plantronics headset. It worked with the Plantronics but the MDA220 often went offline requiring me to fuss with unplugging the device to redirect the headset. I used it for a few days and became mildly frustrated with it. This would never be accepatble by someone that was not technical or had no patients for fussy tech. Overall the MDA2220 is a fail for me purposes. I only wish that I could return it to headsetsdirect but the cleaning crew took the packing out with the trash. The MDA220 will likely go into the trash too.

      The MDA220 can be complicated because you’re adapting USB headsets to a deskphone. An A/C adapter may also come into play to help with how devices are defaulted. There are much easier solutions available for ShoreTel phones that don’t require the MDA220.
