How do you tighten the headphone piece?

does the tv have audio in if yes try this,,,,use your tv instead of headphone ,,,, For the PlayStation 4, you can just use a regular set of 3.5mm headphones to hear game audio through the port on the DualShock 4. To do so, from the PS menu, go to Settings > Devices > Audio Devices > output to Headphones > With yourheadphones plugged in select "All Audio" as opposed to "Chat Audio You can also adjust the volume from Audio Devices > Volume Control (Headphones) - tv. this may work

Hello,
don't feel alone this happens on lots of head phone set up. What happens sense the wire run through the top over to the other side and head phone are constantly put on , twisted, adjusted and so forth, the small little wires that are normally soldered to the two wires to each side get loose. Only thing you can do to attempt to fix it yourself, is to take off carefully the right side ear piece, and get to the exposed wires, you will then notice most likely it will be smashed or loose. If you or if you have a friend that knows how to solder, than, you would make sure wire is cleaned, stripped and re- solder it. Than problem will work. I am sure that is the problem, nothing else it could be. Thanks Mike ( premium expert from fixya)

well you have a few options the first is how long have you owned the unit? is the unit still under warranty? if the unit is under warranty contact bose for a replacement unit.
the 2nd if its not under warranty is to open the bose headset and re-solder the right ear piece. If you can tap the right ear piece and the sound becomes intermittent that is a indicator that it is inside that headphone.
If you have a soldering iron and flux/solder Open the ear piece and then attempt to find the loose connection. At this point put a little flux on the the loose wire. Then heat up your soldering iron. Now only take a small bit of lead free solder and attempt to repair the loose connection. If you solder it correctly it should be working perfectly fine

If you need further assistance please feel free to follow up with a comment and i will be here to assist you. If this assisted you please feel free to rate the comment 4 thumbs up. thanks and have a great day.

You can fix this with some soldering skill and a lot of tinkering. its not terribly hard but can damage your ipod or what ever your listening to if you do it incorrectly. On the flip side im looking for a pair of the ear buds with out a cord for a new life in a project. If you need more help or may be interested in working out something email me. n_raven99(at)hotmail.com

Just flip the headphone pad inside out on the Optimus Pro 100 wireless headphones.
Find the 3 screws on each headphone speaker, you have to push the existing cover back, but you'll find them. Remove the 3 screws. Be careful of the speaker wire that will be attached to the cover plate that has the ear pad on it. Also, look carefully at how the components are assembled inside the headphone, as you might disturb their setting. They are easy to return to their proper place if they move.
Gently remove the ear pad, turn it inside out and you will have a new covered ear pad. GENTLY, re-install ear pad onto speaker plate, be careful not to break the speaker wire that is attached. I found a little flat screwdriver helps to pull the edge of the pad over the plate. The ear pad is actually quite strong and can take some abuse, but don't pull the speaker wires loose.
After you have the cover back on, find the screw holes and put the 3 screws back in. Presto, a little cleanup on any loose pieces of covering from the original side and your done for another couple years or so.

That often happens because of a contact on the headphone wiring, The only way to fix it is by taking apart headphones, testing the wire, and checking the headphones solder joints on the speakers and on jack connector, that usually are responsible for this kind of problems.

The usual cause for that is that the headphone jack is loose or the connectors are loose inside the unit and therefore not keeping complete contact with the headphone piece. It can be repaired but would probably be cheaper to get a new MP3 if that is the sansa one.

I had this problem as well. I would get sound from headphones but unplugging them I had no sound from the builtin speaker.

When you plug in your headphones it moves a thin piece of metal in the jack which interrupts a connection (this is a good thing) so it can know when to disable the internal speaker. When you unplug your headphones the piece of metal moves back and it enables the internal speaker again.

I was able to fix this by taking apart my x51v and bending the piece of metal a little while the headphones are plugged in so that it will contact better when the headphones are unplugged,

To take your axim apart there are 4 screws on the back underneath the rubber grips that you need to take out. Then you can just slide a finger nail up and down each side to remove the front and back of the casing. The back you will need to swing out from the bottom since it hooks over the headphone jack. I unplugged the small wire that connects the front half of the case to the guts using a tiny flat screwdriver.

Inside on the back, there is a black plastic plate that is held on by 4 more screws. Take that off.

Now you can see the headphone jack. I plugged in my headphones and used a small flat screwdriver to push against the headphone jack on the bottom piece of metal on the right side with the axim face down. You can observe the piece I mean by looking at the side of the headphone jack when you plug and unplug headphones. It moves perhaps 1/32 of an inch.

Your goal is to bend the piece of metal closer to where it is when no headphones are plugged in. The only way to bend it properly is to do it when the headphones are in.

Sorry if this isn't clear enough. I'm not sure if this is a permanent fix or not but it's worked for me.

if there isn't screws to take the MP3 player apart then their are clips on the inside
Unscrew the screws (or if you have clips from the on/off switch use a screw driver to open it. this isn't the most safest way to open it i could break so this is a last opption.)
ussing a sodering iron resoder the conection between the loose headphone jack and the curcit board.

(you can pick up a sodering iron at Radio shack for as low as 10$)

only one of my headphones is working i started to notice it a couple of days ago what does that mean?
