Headphones are electronic audio device that people wear over their ears. They let people hear sounds on a walkman, MP3 player, mobile phone or computer. Headphones come in many different sizes from big to small. They are also known as earphones, stereophones, headsets or even 'cans'. Earbuds are inserted into the ear.[1] Headphones typically uses small plug for connection. Some use a Bluetooth connection so they don't have the cord in the way.[2] Some sources say Bluetooth headphones are riskier than wired headphones because of the radiation emitted by Bluetooth.[3]
There is a risk of deafness if listening to headphones with a high volume for a long time.
