In times like these, people are always on the go. They need to be moving all the time, from home to work, or to school, or anywhere else. The headphones give us the possibility of carrying all our music on the go, only for ourselfs, they give us our own space. They also help to avoid all the noise of the city. But all these advantages can be also seen as disadvantages if we look at them as a way of escaping the world, and not allowing us to hear what is happening around on the streets, leading to a possible accident.
If they are not used properly they can cause serious ear problems. They could cause trauma to the perception of high tones of the ear. At first it could be temporary, but the wrong use of headphones for long periods of time can make those traumas into irreversible ones (Explained by Edgar Chiossone Lares, specialist of the Medical Group of Otolaryngology)
