I listen to a lot of sleep aid videos at night through my earbuds. Often their volume gets very quiet. I've noticed that when it does, there is a whining sound that comes through in the background. Ive had it happen with two pairs of earbuds and between two phones. The ones I'm using now are https://www.amazon.com/gp/aw/d/B082MDWLK3?psc=1&ref=ppx_pop_mob_b_asin_title and the ones I had before that were https://www.amazon.com/gp/aw/d/B06XL11BJY/ref=ppx_yo_mob_b_inactive_ship_o0_img?ie=UTF8&psc=1 . Current phone is LG g7 Thinq, previous was Samsung Galaxy 7. If this isn't the right section to post this in I apologize, new here
