The electronic gadgets in the market have proliferated in the market from media players to phones to palmtops and personal computers. Headphones have virtually become an essential accessory to all these devices. Those who use headphones, invariably use them for long hours. This could lead to hearing impairment, temporary or permanent, especially if the volume is high.

In some countries, there are restrictions to using the headphones while driving vehicles including using earphones in one ear. The drivers face the risk of not hearing external noise such as car horn losing the awareness of the situation which can cause accidents. There are other activities that should either keep away from using of headphones or keep it at a low volume.
