Earphone's volume level question

Hi experts, At first, i though it may be a earphone / device failure, but after i experience that issue with several devices, i decided to ask:

Here it is: With some Stereo (natively stereo anyway) mp3 players, although the earhphones (headphone) are totally stereo, the "left" earphone gives noticeably higher sound / volume level than the right earphone when compared. However, against the fault probablity of my ears, i put left earphone to my right ear, the result is ; again the left earphone (on my right ear) gives higher / volume.

Lately, i heard something like "channel separation" has some value e.g. : channel separation: 35db , SNR : 85db on my mp3 player. Is it related to this?

Why does left earphone usually gives betther / higher volume than right earphone? Is it normal or what's the technical explanation?

Note: It's not song-specific. I tried a lot of songs with more than one device / earphones...

Thanks...

So, is it a hardware fault or is it a device deficiency? I mean, is all the same models of my mp3 players have the same problem or it special for mine?

Finally, to understand better, isn't that)low right earphone sound) related to channel seperation? Because player is brand-new.

Thanks.

Not sure what you mean by this last: Different *players* as well as different *phones*? If the problem is only on one player then it is a stereo balance problem. If it is only on one pair of phones then it's a problem with one of the drivers. And some songs may naturally have more output in one channel, though not common. But if you notice this with all players and all phones and all songs, then it's a clear sign of really strange musical preferences!

Tried with another earphones on same player with same strongs, almost same experience. Some songs have more loud on left channel emphasised. I don't record them they're mp3s.

Sounds like the channel balance on the player needs adjustment. Isn't there a control for this? On some devices there may not be a "balance" control, but instead individual left and right volume controls that normally turn as one knob with a concentric surround. The surround is deliberately hard to turn separately, so that when you just turn the apparently-single knob you are turning both controls together.

I have a dumb question: are you absolutely sure you're pushing the jack in all the way?

What do you mean, my hands are free during listening. However, i'm about to conclude most of the songs or at least my songs are recorded in left stereo channel priority / balanced.

I mean, when you connect the earphones to your player, do you press firmly on the connector to make sure the plug is completely inserted into the jack?

What you do with your hands while listening is irrelevant.
