A slight tap or wiggle of the volume knob would sometimes rectify the problem, but more often than not I had to adjust the knob even more to try and find proper balance. The slippers were to small they didnt even go on my foot but only half way Connectivity is great, it doesnt matter which pocket my phone is tucked into the signal stays strong. I do recommend 1+ if stay in you ears, best sounding earbuds found, I tried technics, galaxy buds pro , AirPods Pro , Freebuds pro hammerheads pro several others and say this sound Cambridge Audio best specially if volume junkie . Not as much arch support as the hiking Keens but still very comfortable. The color is off, there’s stains on it, and it’s NOT sturdy at all. I received the jacket today and its totally different from what I bought with respect to the color. Whoo hoo! They are also easy to install. im very pleased.
