Traffic laws are made by states, so there is no single answer for the whole of the US.
In most places, double earphone cannot be used while operating a vehicle, but one earphone or a telephone head piece can.
to listen to music yes you do but not for playing games and stuff like that
My guess to why they are more popular is that earphones are smaller, portable and easy to store. And they're easier to hide when you want to listen to music but aren't permitted (in school, for example)
It is used by lots of different people, they put music on the MP3 player and listen to it through the earphones, it also a good appliance for when you have nothing else to do and want to listen to music when your bored. Also music helps pass the time!
It depends what the earphones are for. If they're simply for you to listen to music while you work - that's at the discretion of the employer. If they're protective earphones to reduce noise in a factory - that's a health & safety issue - and they are required by law to protect your hearing from loud noise !

plug earphones into your computer....
Yes, there is a difference between radio earphones and iPod earphones. Radio earphones are designed to receive FM radio signals and often have a built-in tuner, allowing users to listen to radio stations directly through the earphones. In contrast, iPod earphones, typically designed for use with Apple devices, primarily function as audio output devices for music, podcasts, and other media stored on the iPod, without radio capabilities.
Yes, and no. You will be able to LISTEN to the phone (i.e. play music) on any earphones, but you won't be able to TALK on the phone unless your earphones/buds have a microphone built in. Look at the plug to find out whether or not you have a microphone. Listen-only earphones have 3 conductors: the tip of the plug, the sleeve (the longest metal part), and a single ring in between the tip and the sleeve. Earphones with a microphone have 4 conductors, and TWO rings between the tip and the sleeve.

No, you do not. The iPod Touch 3rd generation comes with built-in speakers, so you can just play the music out loud.

No the headphones are only for communication between the driver and team.
