Streaming audio cuts out from both ears when the left stops talking to the right. From this article:
“The fundamental drawback of their approach is that they rely on a 2.4 GHz signal to transfer information between the hearing aids. The technical characteristics of the signal means that it is inefficient to transmit the signal in a straight line between both ears. Instead, the 2.4 GHz signal relies on reflections from walls and other hard surfaces when it’s transmitted from one hearing aid and received by the hearing aid on the opposite ear… Provided there are hard surfaces in the wearer’s immediate vicinity then the signals are transmitted successfully between the ears and the wearer enjoys a continuous high-quality streamed signal. The problem arises when there are no hard surfaces such as walls and ceilings to facilitate transmission between the ears, such as in large halls or outdoor spaces.”
