Headphones messed up?

I just bought a new pair of headphones about a week ago, and i either a) convinced myself that one side is quieter from sheer paranoia or one side really is quieter. The only thing i can think of that would damage my headphones is that i wrap them around my mp3 player (4in lengthwise) kinda tightly, would that affect the wiring? My previous 2 pairs had the same problem, with the left sides not working at all. But one was old, and (apparently) the second one was defective somehow.

What kind of headphones are they?

If they're "ear bud" style with silicone cushions that go in the ear it's possible that the left side isn't sealing properly. You might try a different size silicone cushion for that side -- many earphones are packaged with small, medium and large sets. There's no rule that says both sides should be the same size. You might also try buying a set of replacement cushions made out of foam -- these work better for me than the silicone ones.

Of course, it's possible that you got a bad set. And wrapping them too tightly can definitely break the wiring connection -- they're usually not very strong.

Just a thought that I really hope does not offend you....

Pick up a telephone, listen to the dial tone with your right ear, then listen to it with your left ear. Will either rule in or out a partial loss of hearing in your left ear.

Just wanted to add that yes, wrapping your headphones around your iPod/MP3 player can mess up the wires, but only if you leave them plugged into your device. If you take the plug out, and wrap them gently around it, they should be fine.

ah, thank you for the advice, and no, my left ear isnt screwed up Mine are the earbud style, I'll try to switch the foam things.

Are they Skullcandy? If so, they have a lifetime warranty, I returned a year old pair that started having a popping noise in the left ear, and got a new pair in about 2 weeks.

I really did not figure it was your hearing, I only wondered since this is not the only set of headphones you have this issue with and it has always been the left side that you have the issue with.

Quite honestly, I have always found that the music on regular speakers for the computer, as well as stereo speakers, usually come through louder on one side than the other. I have been told that is the stereo effect because even though most sounds come through both speakers, certain sounds only come through one speaker while other sounds come through the other one.

I don't really know but maybe that is all it is with your headsets.
