Precautions while using Earphones
You also need to realize that having headphones in can make you less aware of your surroundings and this makes you more likely to have accidents. You need to avoid this possibility by keeping your headphones out if you are going to be crossing the road etc. especially if they are noise cancelling headphones. On a train its fine, but when youre walking to the station you need to be more careful and you shouldnt listen while driving.
