My headphones are out of phase!

nd2023

Banned
I yanked the cord of my headphones too hard, and now no matter which audio device I plug it in to, the audio is L-R for both ears. When listening to a stereo FM station, it's 180 degrees out of phase audio plus static, and nothing when listening to FM in mono. This is the first time this ever happened, usually headphones fail by having the audio cut out completely. I wonder how this happened!

I second the motion Doc...

Yeah, you are hearing left hot to right hot and only difference material.
Probably a lot of songs have become instrumentals and the announcers are only a quiet crackling.
Felix Mendelsohhn would have liked your headset.
He wrote a series called Lieder ohne Worte (Songs without Words).
 
You could pay good money for a processor that does the same thing, or your could just disconnect the common lead, as
you have done accidentally. Not sure how I figured it out at 17 years old, but I did.
This is how I removed vocals in 1978 when 2 friends and I sang in a talent show.
It worked really well on "Come on Down to My Boat Baby" "Sounds of Silence" and a Beatles' song (I forget which one).
People hadn't heard of Karaoke yet, and some had a hard time believing were we the vocalists, since it was obviously the
commercial releases of the songs.
 
There may be a doctor in Transylvania that does operations to rephase your ears to the headphones, just be sure you don't donate any spare parts.
 
Yes this is the cheap way of vocal cut,no need for computers and vocal removal processors that were advertise in those old electronic's magizines. I agree with the Doc.lost of ground lead.
 
These headphones might be useful when playing with an audio processor, I'm not going to throw them away just yet.
 
Ah. Hafler surround decoding at it's most affordable.<G> An open shield on the cable to the Rear Channel amp on this computer provides the same service here. Quite a pleasant result actually. And it REALLY shows up how awful low bitrate files are. UGH!

Early stereo recordings that had some or all the vocalists and maybe the percussions on one side and some or none of the vocalists but the remaining instrumentals on the other side should sound like like fake stereo. That is, everything will be on both sides, but be out of phase, that is with a big hole in the center.
 
If I'm listening to headphones and change the audio so that the left ear gets the L audio and the right ear gets the -R (right channel inverted) audio, it seems like the music is originating from inside my head.

It is. That's true high fidelity.

Actually, mono (or common) source material will sound that way when the channels are in phase but will sound like they are coming from the left and right when they are out of phase. The cans are naturally out of phase in your situation, so flipping a switch to put them out of phase actually puts them in phase.

Whensoever ye shall connecteth speakers, it matters not that the red goeth to the + and the black to the - so long as they are the same on both sides.

When I was a young warthog and was babysitting an FM radio transmitter, we monitored the station in stereo as did the studio folks, so when a listener called to say he could hear the station in stereo but not in mono, I flipped the monitor to mono and, low and behold, it went silent. Well, earlier that day our phone lines were dug up, cut, and spliced back together but out of phase. So, I walked over to where the phone lines entered the shack and reversed one of the pairs, left or right but not both, and all was saved, and I could get back to sleep.
