I plug my iPad into to headphone jack but I don't know how to get it to work

is it a tablet?....phone?....laptop??? you dont say. If it is a laptop..make sure you are plugging it into the 'headphone' jack...not the input or mike jack. they all look the same except for color. if itis a tablet...go into the settings and see that the headphone jack is set to 'headphones' and not 'speaker'
It is possible you have a defective headphone jack...there is a small switch build into the jack that disconnects the speakers and turns the headphone audio path to the headphones. sorry..now I see what the device is
"same answer"

Yes! You need a twin phono plug to 3.5mm jack cable! Connect it to the phono socket at the back of your stereo and the 3.5mm jack to the headphone socket on your iPad.

Aux-in jack is used to play another device such as an Ipod or other sources through your Jensen player, using it as some sort of an amplifier. Look for another port on your Jensen player that says "audio out" or "Spkr" (means speakers) to plug in her headphones. If you can't find any of these ports then you might have purchased a n actual boom box, which does not have the capability to play through headphones, sorry about that.

Great that the problem is solved. You can't close this thread. Just leave it.

If you've got a headphone plugged into the headphone jack remove it. If this issue is (still) there without a headphone plugged in and you have no bluetooth headphone paired (disable Bluetooth to test) then i suggests the headphone jack is faulty. You might have a look if there's dirt and/or dust inside the hole. Carefully try to remove it using a toothpick. Use no needles, no liquids and similar for this.

If the problem disappears with bluetooth disabled check the bluetooth gear.

This is the normal way for this laptop ..leave it always with the headphones on selected in that list ..cause if the main speakers don't work well there is no point in using them ..This way you will run whatever yo will plug in ..speakers or headphones..The only setting difference in headphones and stereo out ..is that for headphones will but the speakers of the laptop when plugged in ..This way it will even help you if the speakers are making weird noises cause they are damaged ..

This set doesn't have a headphone jack, nor does it have RCA audio output jacks. Without one or the other, you're out of luck connecting headphones to this TV.

I remember a product some years ago that allowed adding headphones using a small microphone placed in front of the speaker. This was hooked to a little amplifier that ran the headphones so the volume could be independently controlled. It was marketed as a way to let "hearing-impaired" family members listen to TV shows without needing to make it uncomfortably loud for others. I haven't looked, but something similar might still be available. It's cumbersome, though, and needs power, plus maybe being costly if you find one.

It's possible to add a headphone jack, but you need to know how to do electronic soldering. Find a spot on the case where you can make a hole and mount a headphone jack, then wire it to the speakers. If you want the headphones to cut off the speakers when plugged in, you need a switching jack, and the speaker wires need to be cut and connected to the correct terminals. The switch built into the jack then disconnects the speakers when the headphone plug is in. If you don't need to turn off the speakers it's a little easier. You just need to wire from the jack to the speaker terminals. I've added jacks on quite a few sets. If you don't feel up to it and don't know anyone who is, you can see if a TV shop (if there are any left in your area!) would do it. (The shop I used to work for charged about $20, including the jack, but that was over 10 years ago now.)

Good luck, and thanks for using Fixya!

Could be possibly dirt in Ipad headphone jack (common prob) - put a drop of isopropyl alcohol in Ipad jack - just a drop. You might also check headphones in a computer jack to verify if it is possibly the headphones.

I'm not certain it's not the I-Pod socket or the headphone jack that is playing up? If you can get another pair of headphones (a friends etc) and put them in the socket of the I-Pod, to test it that should clear it up. For if they don't work you know it's the I-Pod socket that's faulty.
If it's the Bose jack that's gone, you better see my tip on dodgy cable/plugs on headphones. You should be able to replace it with the 3.5mm type shown, but I think you can get the thinner type jacks.

The contacts inside the headphone jack are made of a springy metal there is one for the left and one for the right speakers. This happened to my Blackberry and I took it apart and got inside the jack block and re-sprung the contacts. It worked for me... I used a dental pick.
