I recently read this article about ear buds causing hearing loss and it\’s very alarming as MP3 players are so popular today. So you own an iPod or Zen? You probably want to change the earphones / ear buds that comes with it. The article suggests using ear muffs / headphones because they have noise-cancelling which eliminate background noise unlike ear buds. This prevents the user from stepping up the volume of the device, possible for causing hearing loss after just about an hour of listening.
