No sound playing despite being connected and devices showing sound playing.

When I connect my airpods to my Windows laptop or iPhone, they are not playing any sound at all, with no connection signal or anything. On Windows, the sound panel shows audio playing through the device, but I cannot hear anything on the airpods. Similarly, my iPhone also seems to have no trouble connecting to them. When I play audio, however, nothing comes through, and eventually the airpods disconnect and audio plays through the iPhone speaker.
