You will need the Bernafon Soundgate bluetooth device. That’s what actually connects to the bluetooth phone. I use the Plantronics MDA200 device. It has a port where you connect a “headset” and they also make a Plantronics BT300 dongle (Bluetooth) to fit that port on the MDA200 to connect to a wireless Bluetooth headset. To the MDA200 and BT300 your Bernafon Soundgate looks like a wireless Bluetooth headset.
The MDA200 connects to either your phone or your computer, depending on how your company handles office calls. If you use an actual phone and not your computer you will also need the Plantronics EHS cable for your specific phone model. The phone needs to be a model that has a headset jack but there is a way to do it if you don’t have that type of phone, but headset jack is better.
So you would insert the BT300 into the MDA200. Then you would connect the MDA200 to the phone using the EHS cable for that specific phone model (different cable for different phones). Then you would pair your Soundgate bluetooth device to the BT300, or for people with other brands of hearing aids, pair your hearing aid bluetooth phone device to the BT300. Your bluetooth phone device will look like a bluetooth headset to the MDA200. Mine works great. There are two wheels for adjustments on the bottom of the MDA200 and I did have to fiddle with those to get a good connection with no static.
