This is a weird glitch or something. When I put my apple earbuds in my iphone 6s, my left earbud doesn’t sound as loud as the right one. Then I found out when I have my earbuds in my iphone, the calling speaker is also working. So the calling speaker takes like half of the sound of my left earbud. Does anyone have an answer?
Hi, The first thing you should do is backup your iPhone then do a restore. https://support.apple.com/en-us/HT201252 Also get a wooden toothpick and clean out your headphone jack. Do NOT use a paper clip or anything metal.
