Can Ear Pieces For Phones Work As Computer Gaming Headphones?

There are going to be debates about this answer but NO, you cannot get the range of sound from a phone ear piece that you can from a good headphone. The sounds are tinny and unrealistic from an earbud. You need to hear the actual explosion and listen for footsteps off on one side to really play a good game. Only a good headset will work. Don't try to use any of those $10 headsets either.  Like I said, there are debates on this issue but you really do get what you pay for when it comes to gaming.
