I noticed recently that my AirPods were not as loud as they used to be. I checked the volume and it was at its maximum. I then went to adjust them and when I touched the right one it sounded great. As soon as I let go of it, it went back to low. The same happens with the left one. So, when I barely place my index fingers on each AirPod I get great quality audio. Needless to say, I cannot hold my fingers on them in order to get the sound I should have. I have cleaned them, relearned them and tried various other suggestions that I found online. Any suggestions before I break down and purchase new ones? Thanks!
