What smartphone do you use, if you use the iPhone with IOS 13 there is some good news.
IOS 13 has added a feature to help you monitor the noise around you to see if you’re being exposed to dangerous sound levels, or even if you’re simply talking too loud, and to help address a much more common source of hearing damage which is your headphones
In addition to collecting noise data from your Apple Watch, a new “Hearing” section inside the iPhone’s Health app also monitors your headphone audio levels, letting you know if you’re listening to music at unsafe volumes, and this feature is available for any set of headphones
Try to see these levels on your phone for the your usage and check if there is something unusual, may be this is causing the headaches
