Headphone Channels have reversed

Postby Big Kahuna » Tue Feb 21, 2012 11:46 pm

I just got my headphones back from being repaired and they seem to be working fine except for one problem, the channels have completely reversed so if I pan left the sound moves to my right headphone. I decided to just put my headphones on in reverse and that seems to have fixed the problem for now.
I'm curious as to what could cause this to happen and whether I will encounter any problems from wearing my headphones in reverse?

Some headphones are symmetrical, so it doesn't matter which way round you wear them, others are designed to be worn one way. If you got them repaired locally I'd get them fixed for no charge, worth doing in case someone else picks them up.

What headphones are they?

Maybe the repairer just plugged the lrad back in the wrong way round, so all you have to do is to unplug and re-plug correctly.

Most headphones are wired with a common connection to the 'cold' side of both transducers (which is wired to the sleeve terminal of the plug), and then separatea wires from the 'hot' sides of each transducer. These are wired to the plug tip for the left channel and the plug ring for the right channel.

It could be that in repairing your headphones the plug has been miswired, or that the wrong wires were connected to the wrong terminals in the headphone itself. Did the repair involve replacing or repairing the cable at all?

Alternatively, as John suggests, some headphones have a removable lead with a plug/socket (or two sockets) arrangement at the headphone end, and it might simply be that in repairingt he headphones these have been connected the wrong way around.

In most cases it makes no difference whch way you wear the headphones because the ear cups are entirely symmetrical, but in some cases the ear pads are shaped and/or the transducers are angled inside the shells, in which case weraing them backwards might affect the comfort or tonality.

I'd take the headphones back to your repairer and point out the problem if I were you!
