I'm trying to take apart the left headphone to fix an audio problem (no sound from left channel). This thing is made extremely tight with nothing visible to start the teardown process. Any help?http://www.bhphotovideo.com/images/image...
"Ok, problem for this case has been found and we have solution!
If your Jabra Move headphones not produce sound in left channel in wireless mode - that's bad switching contact in jack connector!
For checking if that your problem and solution too you must try to bend and close contact by hand for left channel pin!
This is jack have 7 pins (has 3 switching contacts for switching mode with cable/without cable)
Connector was found as 3.5mm Female Audio Connector 7 Pin SMD Stereo Headphone Jack or same smd 7 pin earphone socket jack and I found Model number: PJ-382-7P:
For the disassemble JABRA MOVE headphones please read post by Muro, thank you @mrmuro ;) :
To dissasemble you don't need to unscrew anything, you just have to get the back part of the speaker in one hand and the other part(the one with earspillow) in the other and rotate the second one counter clockwise. If you put the right force you will feel a click and the headphones will be dissasembled.It's not so easy, but normally it could be done without breaking the headphones.
For easy untwisting and for disassembly of the headphones cups you can is not removing ear pillows before untwisting, and tightly hold by hand via pillow. But be very careful to avoid damaging of the ear pillows! To better understand the direction of untwisting, see picture:
Headphones and cups have the three elements of simple mechanical lock:
BTW, for replace jack connector (it has SMD/SMT type) you must be able to work with surface mount soldering, so as not to damage the board! That Is not difficult, for this you must have: a soldering iron with a small tip, good quality flux, solder, and desoldering ribbon. Or better take help for such work from specialist!
'''Important UPDATE:
For me not helped a good flux and desoldering ribbon - for quality soldering you must have the soldering-iron with hot air tip! And unfortunately some contact tracks has been detached when I tried to desoldering of the connector( Because soldering from manufacturer has high-temperature solder!'''
"I finally did the same thing @mrmuro describes in his comment – except I used a knfe as a cantilever to pry a bit to loosen the glue inside before I twisted it off. It's stuck pretty good.
These are the comments accompanying the pictures in the link:

""It's hard to see what's going on there due to the clap and tape, and all the glue underneath.
[I removed the] clamp, tape and [pushed] the cable in to make room
in the circle you can see the wire that has gotten caught by the cable when it twists inside the joint. The result of getting caught is that it is tugged, and thus reducing the contact with the soldering point underneath the glue.
I forgot to take a picture of what I did afterwards, but I removed the glue and soldered the blue cable down onto the board again.
when reassembling, try to place the tiny cables in a way so they will not get caught by the twisting black rubber cable in the joint.""
Disclaimer: You may have another tiny cable at fault, but in my case, it was the blue one.
"So, the problem was that after using the ""Line in"" jack for couple of weeks, the left channel was silent when I switched back to Bluetooth. Both channels did perform normally when plugging the ""Line in"" jack.
Here's what I did just 5 minutes before writing this message:
1) Grabbed and removed the cushion from the left headphone
2) Ignored the screws which stared at me
3) Tried rotating the left headphone off (like in the image user ""arsdezi"" posted) but %#*@, it's too tight
4) Ignored the screws again; they're not the ones holding the headphone part
5) Put on my winter gloves and try rotating the left headphone off with even more force: success
6) The ""Line in"" jack has four contacts; with the tip of a screwdriver, I pressed down the contact that was in the ""deepest"" end of the jack while the headphones were ON and switched to Bluetooth, to test if the sound finally comes out of the left channel: yes, it did
7) Pressed the contact down with force, while soldering some tin on it to hold it down
8) Assembled everything in place
I've had this problem for a while now and even though I've already stumbled upon this message thread months ago, I had some problems with understanding the repair guides here. Not sure if the problem is that they're written in poor English, or if I just can't read English well enough. Probably both, and more the latter.
For months I thought I had to order a new jack connector, pry open the whole %#*@ thing and hope I could assemble it so that it still would even vaguely resemble the headphones I once had. But the repair wasn't hard at all. Didn't even have to order anything.
EDIT: Also realized, that d - amn is a censored word here, even though the word or it's meaning is not vulgar in nature. #justSJWthings ? :D"
Huray! I was able to disassemble and open headphones! Any questions?
But until this time I'm not check pins and cords for resolved my issue with sound: not play left chanel in bluetooth mode, but play all chanels in wired mode.
I will try to solve the problem in a few days(at this week)!"
When outdoors and not around anything solid that can reflect and reinforce the Bluetooth signal from a phone to these (or most Bluetooth headphones), the human body can easily block the signal and cause audio to cut out. This can be shown by placing the phone in your rear pants pockets on the opposite side of the headphone receiver, while in an empty field or parking lot. This is a common problem and many people have discovered it's their body itself "causing" the Bluetooth audio drop outs. I'd like to see if there is a way to open up the cups on the jabra move and extend the antenna across the headband and into the left ear cup.
Thanks guys! This helped a lot! Funny thing is i only plugged in a cable ONCE just to hear how they sound without the bluetooth compression and the jack broke! Ear cushions also disintegrated after a few months! Really crappy quality! i'm thinking of selling them after i repair the jack & buy new cushions.
