Moderation is key; excess of anything can lead to negative consequences, which highlights the importance of moderation in all aspects of life.
I am extremely sensitive to sounds and frequencies generated by electrical devices too; I can hear and feel them from quite a distance. At times, they can become very annoying. This includes headphones, which can sometimes produce a pitch that is rather unpleasant to hear. I always stop using them when they make this pitch, or avoid any devices creating this pitch.
However, I’ve used Bluetooth headphones for years, but I always keep the volume at a level that is tolerable for my ears. I use high-quality headphones though. We are constantly bombarded by UHF and other radio waves in our modern lives. It’s nearly impossible to avoid them, and most people seem to handle this exposure just fine. But, as with anything else, individual experiences and sensitivities can vary.
