This is an age of absolutes. Everybody is absolutely sure about everything. One such alleged absolute truth that is often floated around, mostly on whatsapp, is that using earphones/ headphones is "absolutely" detrimental to one’s hearing. Parents know it, teachers know it and often enough medical professionals cement this.
Now I don’t have a vested interest in the argument, but I do know I love to listen to music on my earphones. Whether I am on a train, on a plane, the running track or an online meeting. And by jove I know they aren’t the villains they are made to be.
If you are someone who feels guilty when using earphones, or one who might need more clarity whether you should gift a pair to a loved one :), here’s a video in the mother tongue with all the info that I think you might need.
