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...

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.

No - channel separation is the maximum separation between the two
channels in terms of volume. 35db is pretty darn poor! If I were you, I'd
be worrying about getting a new player than your earphones.

I would put my money on broken earphones. If they're cheap it's probably
worth your while getting a new pair.

Otherwise, look around the PCB for damaged or corroded connections,
especially near the headphone jack.

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! <g>

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.
