Unless you have a screwy setting on the broadcasting device (try other known good bluetooth devices first to rule this out), then your problem is highly likely the same as mine....

There are bendable pins within the headphone jack on the headphones that are used to determine when the jack is in use or not. They are cheaply made / designed to fail and when they do, this is one of the outcomes (the others are, no sound at all because both switching leads are broken/bent/coated, or no sound in the opposite speaker). Some people have had luck with compressed air and/or a small qtip dipped in strong pure alcohol (isopropyl or something, not drinkable alcohol that has sugars in it...) to clean the jack in the case it is gunked up / coated. But in my case it was physically bent (I presume) and cleaning did nothing.

I soldered the 2 pins/footpads in the far left corner when the opening of the jack is facing towards you (the right channel of the headphone was the one that was dead for me... i think, you could possibly need to fix the lead on the opposite side if your left channel wasn't working but I found the leads to fix mine by using a pair of tweezers to connect the leads while the device was running on bluetooth) jack itself together with a small piece of wire. Seems good so far!

Millions of devices are affected by this issue from headphones to laptops and micro-soldering totally sucks. This would seem to be a designed flaw....

look at your wire conection.

hey ! of course it's possible to open the ear piece !!!!!

all you have to do is to pull the foam off (it's not too hard :)
then you'll have to unscrew 3 tiny screws (get a really tiny screwdriver....and voila :)

i just did it on mine couple of minutes ago

Lots of people have complain about the samething, I'd suggest you to get a pair of Kicker HP541 DJ-Style Over the Ear Headphones (Black)

Usually due to bent driver, worn driver oring or lower bumper cracked, weak or broken feeder spring. Remove head being careful not to tear gasket. Pull the driver and check for bend in shaft or chipped end. If the end of the driver is chipped or rounded, grind tip flat (remove as little as possible ). Piston should hold position in the cylinder and drop down under its own weight. Examine lower bumper. If missing pieces, replace with new. Lube orings with silicone paste (sold at Lowes in plumbing department). Also check for correct nails. Should be 15 degree metal wire. There is an older hitachi nailer with a metal canister (nv50aa) that uses plastic strip nails. These nails are too close together to work properly in the #nv65 gun and will usually shoot two nails. Good luck

What you need to do is cutt off the old 3.5mm jack and buy a new one. Cutt it off 10cm from the end of the plug (this is so you clear any weak or damaged area).
The new plug will have two lugs (one small and one bigger) and a large metal flange with a T piece flange on the end. Strip back the wire on the cable, you should see two coloured wires and some earth wires. The two coloured wires need to be soldered to the two lugs (left & right) if you get the channels the wrong way reverse them it wont hurt the headphones. The earth wires (all) solder on the large flange. Don't let solder or wires from the L&R touch the earths or each other. The T part grips the the black cable to prevent it being pulled. Bend the T to grip it. The Body of the plug should be put on the wire before you attach the rest of the plug. Slide it over the plug when done.
If the sound seems 'spaced' out then an earth wire is not connecting right to the metal flange.

THE BEST WAY TO DO THIS IS TO GET THE REPLACEMENT JACK FROM AN AUDIO OR MUSICAL SUPPLIES SHOP.. ONCE YOU HAVE THIS CUT BACK THE CABLE OUTER SLEEVE TO SHOW THE CONNECTORS AND CABLES ON THE JACK..GET A SOLDERING IRON READY WITH SOLDER.. STRIP BACK A SMALL AMOUNT OT THE CABLE SLEEVE TO SHOW THE WIRES THEN STRIP BACK EACH OF THE CABLES AND TWIST THE ENDS SLIGHTLY..GET THE SOLDERING IRON HOT AND TOUCH THE WIRE TO THE END WHILST BRINGING TEH SOLDER TO THE WIRE TIP. IF TEH IRON AND WIRE ARE HOT ENOUGH A SMALL AMOUNT OF SOLDER WILL MELT ON TO THE WIRE TIP.. DONT HOLD THE WIRE TO LONG OR THE HEAT WILL MELT THE PLASTIC COATING., DI THE SAME FOR THE OTHER WIRE.THEN UNSREW TH NEW JACK YOU SHOULD SEE EITHER TWO OR THREE CONNECTORS MATCH UP THE NEW WITH THE OLD ON THE CONNECTOR AND SILDER ON ONE BY ONE THE SAME WAY JUST HOLD THE WIRE AND IRON TO THE PLATE AND HEAT WILL CAUSE THE SOLDER TO ATTATCH TO NEW CONNECTIONS..MAKE SURE YOU HAVE PUT THE SLEEVE ON THE WIRE BEFORE YOU SOLDER OR YOU MAY HAVE TO TAKE IT OFF AGAIN TO PUT THE JACK BAK TOGETHER..TAKE YOUR TIME WIT THIS AS IF YOU TRY TO HURRY THE SOLDEDRING PART IT CAN BE MESSY AND NOT TAKE PROPERLY AND CAUSE BREAKAGE AWAY LATER IF THE JACK IS PULLED.. ONCE THE WIRES ARE SOLDERED ON TURN OVER THE GRIPS AND IT SHOULD WORK FINE.. I USUALLY GO FOR THE METAL TYPE JACKS AS THEY ARE STRONGER AND EASIER TO SOLDER.. GOOD LUCK A...
