We are using two headsets in close proximity and they never maintain their connection and definitely jump receivers. We have run about 75 couples using dozens of versions of this setup with tremendous difficulty. We now place the receivers right next to each headset, pair each individually, then, within our 20 minute recording one or both always drop. Sometimes they return, sometimes they do not. Often one headset becomes received by both receivers (we have many data files that show this). Typically, they are very difficult to get connected in the first place when near one another.
At this point, we would prefer to make them corded. Is there any hardware already available to transmit by cord? The USB provided is power only.
