Earphones? Ear pieces are sometimes worn so they can stay in check with the current song. Often on stage there's so much noise, it can be helpful to have.\n\nI've noticed more so, that the ear pieces they wear are are ear plugs to protect their ears from the high decibels emitted from the speakers. It's really a good idea for concert goers as well, you'll save your hearing and be greatful when you're a lot older.

a microphone and speakers or headphones

Since your ears are separated from each other by a fixed distance, one ear generally receives the signal before the other one does.  Depending upon the differential between the two, your brain computes the angle from which the sound originates.  If both hear it at the same moment, it is coming from directly ahead or behind.

They are horrid.  When I get into it and air guitar I use both hands. But when you use both hands it looks liek your tryign to pleasure yourself.  I think people who dont play guitar only use one hand.  Its nhatural to use two if you play guitar because both hands are always moving.

They control the Behavior of Sound Waves(Reflection, Refraction, and Diffraction)\n\nreflection of sound waves in auditoriums and concert halls do not always lead to displeasing results, especially if the reflections are designed right. Smooth walls have a tendency to direct sound waves in a specific direction. Subsequently the use of smooth walls in an auditorium will cause spectators to receive a large amount of sound from one location along the wall; there would be only one possible path by which sound waves could travel from the speakers to the listener. The auditorium would not seem to be as lively and full of sound. Rough walls tend to diffuse sound, reflecting it in a variety of directions. This allows a spectator to perceive sounds from every part of the room, making it seem lively and full. For this reason, auditorium and concert hall designers prefer construction materials which are rough rather than smooth.

Many do (rely only on natural acoustics.)  It often depends on the use in question.  Most symphony halls ahve sound systems, but do not use them in the hall when the symphone is playing.  The natural sound and sound balance is a key to the experience of listening to a classical orchestra.

You can do that, but try not to play them too close together. Sometimes bands' songs all sound the same i.e. Everclear. It worked for them, but its not too talented to do something like that.

I read all the previous answers and agree with most that it may be incurable as it is the sign of hearing damage usually due to loud noises (music, concerts, bands, and often in men, the use of many power tools.) I think it is important that you use ear protection even when mowing the lawn to help prevent further problems. Those squeezable earplugs are good. \nI have used ear protection for years even at concerts. I discretely put some silicon earplugs in and loosen them just enough to hear and enjoy the music but not leave with my ears ringing. I hope they do find a cure for tinnitus as so many people suffer from it and the upcoming generation likes everything even louder, not realizing the consequences.

If you examine properly, there will be a hole to insert your headphone pin. It will be written above it  or you can find a little symbol of headphones somewhere around it. If you insert your headphone pin into it, the sound will come through the headphones in both ears. You dont even need to remove the speakers.

There could be a microphone problem on the side of the person you are talking to.  Ask them to call someone else and see if anyone else can hear them.  If no one else can, there's the problem.\nAlso, make sure you can hear other people when you talk to them.  If you cannot hear other people, then the problem could be with your headphones.

Not to be rude or anything.. there are NO ear lobes on our face. if you are talkin about the external ear though... lemme tell you that external ear or pinna in human beings is a vestige. In other animals and our predecessors it was used to amplify incoming auditory signals

Earplugs. Seriously, they are lifesavers. Get the ones that have 32 decibels of attenuation. You'll never be bothered again.

Ya, beacause somewat, the ear is connected to the mouth.

Who are they, the new Spice Girls?  My speakers do not work so I could not hear them...but I say like whatever music you want to!  I listen to a lot of stuff that my friends make fun of me for.
