Why does only one earphone in my iPhone work?

I've had my iPhone 4 for about a year and a half now. When i got it all earphones worked, now only one works and same with speakers and docks. At first i thought i had blown my earphones but they work in everything else just not my phone.

That's what happened to me. Maybe it's just like that. So I just got new earphones.

Well my friend, that's what happens. When you over use headphones for a long time, they will tend to be that way. If you refuse to change your headphones. Then it will keep wearing out until it can work at all! There are actually some cheap ones at Walmart for only $3.95, and some at the dollar store for a dollar!

I bought hundred dollar headphones and they didn't work in on eear but they worked in the other. This is true with all the other headphones I have bought. It works in all my other devices but only one on my phone.

  • Why does only one speaker work when I connect my iphone to my Hi Fi system? I brought a brand new Hi Fi system today, tested in the shop with my iPhone connected and it worked fine, both speakers working. I tried it when I got home and now only one speaker works when my iPhone is connected using the audio in cable. Both speakers work fine when a CD is playing, why is this happening?
  • Why does only one speaker work on my iphone? Its been bothering me since it came out of the box. The right speaker at the bottom works just fine but the left, I never get a sound out of it. Is my iphone defective or maybe there's a setting to fix that? I don't know
  • Why does only one speaker on my iPhone 4 work? My boyfriend has the same phone as me only he has not had it as long as me. When we play music on his phone both speakers work. But on mine the left one doesn't work. I have never damaged my phone. Always had a protective case on it. I'm very easy on it. What's wrong with mine? Could it have been messed up from the start? Or is there a thing I can change the setting. I checked the music In the settings and the speaker thing is in the middle.
  • Why does my iPhone only work on speaker but not regular? If I receive a phone call (the ringer works) I can only hear the caller if it's on speaker. Also if I play a song (music or YouTube) it doesn't play out loud, but I see the little equalizer thinkers going.
