Mp3 audio the headphone jack is lose so i cant hear anything

Plug headphone plugs in audio jack.

Turn speakers off in sound menu if available. Then turn up volume to hear in headphones.

If you plug some headphones into that jack and can hear your music from it then no you cant use it with an mp3 player.

it's usually the first contact (ground) of the headphone jack module that loses it's elasticity and does no longer touch the headphone plug properly. you can try to pull it back inward from the outside using a dentist tool or a sewing needle. if that fails you have to open the ipod touch and push the contact inward or replace the jack module.

I took the advice of one of your correspondents by connecting my Sony ICD-SX365 recorder to my iMac with a simple audio cable by inserting the output jack in the recorder's slot for headphones and the input jack in the iMac's slot for microphones. I used the freeware program Audacity to import the track onto the computer and Switch to convert the file to mp3.

The headphone jack is defective - get a refund if you still can, or find out from jWin if it is still in warranty (doubtful). A replacement headphone jack is not an orderable part.

I agree with Solution 5. The copper pins in the jack that make the connection to your headphone plug are bent in such a way that they are springy and will make a good tight connection to the plug. When those copper connections get worn, they are not so springy and they bend inward causing you to lose audio on one side of your headphones unless you wiggle the plug and find that sweet spot that makes a connection. Then you have to hold the wire to keep pressure on it... it gets annoying.

You can open the case and there are slots in the headphone jack that you can get a hook scribe (like the dentists use) or safety pin to bent those copper connections back out. Don't bend them too far or they will break. You can also pick get a new part for $25 or a used part much cheaper. Once you iPod is open, it's a matter of a couple screws and a ribbon cable to replace the jack. Problem solved!

you have a bad head phone jack

You have to sold the jack to the board again, probably one of the conectors lose contact. good luck
