Sound cuts out when I connect earphones

Through the 3.5mm headphone jack from your headphones, its a pretty small hole usually to the front of the tv set, being so small you may have to look for it. If it is wireless you will need to connect the main headphone system to the back of your TV (audio in jack) then ensure system is powered on and headphones are charged.

Some Kindles have an earphone jack and some don't You can use earphones only if your Kindle has the earphone jack. It is the mini-jack like used in iPods and iPhones and many headphones (as opposed to ear buds) use a larger size jack.
Adapters are available. Try Radio Shack for adapters and lead cables. Keep in mind that most earphones require more power to operate than earbuds do and the Kindle may not be able to sufficiently power headphones to get any decent volume.

The speaker cutout feature whenever the headphone jack is connected is a hard-wired feature of the headphone connector, and cannot normally be bypassed without further electronic circuitry and the associated surgery to install a custom modification in the TV. In order to keep the TV speakers on while using the sound elsewhere, you will have to take the audio output from the IR Audio port, if there is one.

It is possible as when the jack is used with a plug into it, it is designed to cut the sound to the speakers in the set.

Please plug/ connect this wireless headphone base unit in Line Out jacks at back of amplifier to get sound in headphone and turn down amplifier volume control to shut off its speaker sound.
Thanks.

There are at least three different sizes of headphone jacks. You can purchase an inexpensive adapter at Radio Shack or just about any store that sells electronics. Also, you said "audio" jack. Be sure to plug into the HEADPHONES or PHONES jack if the set has one -- some do and some don't.

the headphone socket acts as a switch for main audio and headphone line. either u have a defective socket or the power amp is defective. headphone line is driven by a preamp, which is working - if power amp is defective- headphone works but power amp fails. try changing the headphone socket first. 

Try plugging in a headphone and see if that allows you to hear it play, or hear rushing noise (squelch open). If it does, then you know the scanner is working, and the only problem is the earphone jack, or the speaker and/or wires to it. Try removing the headphone again (try several times) to see if the only problem was dirty terminals inside the jack that disconnects the speaker when the headphone is connected. I have found several portable electronics that this was the only problem. At least it costs nothing to see if it helps!

The bare copper conductor wire is the screening/common earth to the two signal wires of green and red. The important connection is the copper wire which goes to the jack plug earth which is the section furthest from the tip. The other two are the left and right signal connections. If you get these the wrong way round you will just have to swap them over. Check if they are the right way round by using the balance control on your amplifier or whatever. Have you checked that the problem is not with the headphone amplifier within your equipment? Don't rely on OK sound from loudspeakers as the headphones may be fed from separate op-amp output chip. Try another pair of cheap and cheerful headphones to make sure.

Sound not coming out of one side of the headphone is an indication of connection failure, so that means you have to see where its 'broken' from, either inside the headphone on on the wire somewhere. Usually it happens at the jack, especially if you use an ipod as it tends to get moved alot in pockets, etc..

If this is the case, you could try to cut the wire from where you suspect its broken, and get a 3.5mm (or whatever the original size is) replacement (Do-it-yourself) jack from Radio shack or electronics store.

THen you would have to cut the wire, strip the the rubber coating off, and then if applicable, carefully strip the very thin layer of further insulation thats on the wire it self. Otherwise you would directly connect the cables to the prongs/connections located on the replacement jack. And depending on the jack you would screw it in place or soldier it with soldier and soldiering gun.

If its broken in the headphone or at the headphone, thats much harder to do as you would have to open the head/earphone case and soldier it that way and get it back together in one piece.

Next time don't buy bose headphones and by something cheaper, bose isn't that great, skullcandy is pretty good too. Sennheiser is the best though in my opinion. albieit its expensive too..
