Touch controls & auto pause intermittent

I got Momentum 4s about three months ago. Love them! But is there a fix for intermittent touch controls and auto pause/off head sensor failure? Since the start, literally day one, the on/off head sensor feature has worked less than it hasn’t. And now my touch controls sometimes don’t work at all (like it’s not detecting my touch). There’s no software update available and I toggled touch controls off and on and rebooted them which fixed it, but it’s not ideal for the price I’ve paid for them. And the sensor is clean - that literally didn’t work the first time I got them out of the box. Thanks in advance!
