Connecting headphones to my jack-less TV

My LG 32LN5300 TV lacks a headphone jack, but I want to connect my headphones to it. It has a bunch of outputs on the back (see attached spec sheet for connection options), including optical connections. Any advice on how I can do that?

I honestly don't know :-) Would the headphones plug into the AUX jack?

The 3.5 mm jack on the left, but I doubt it will work well because there is no volume control. You’ll probably have to send the signal from the converter to a headphone amplifier.

Perhaps providing the make/model number of the headphones being used would help.

Looks like you just need an adapter that accepts the headphone jack and splits it into the two red & while RCA plugs that you plug into the tv audio-out sockets on your set. You can find these at Radio Shack or an electronics store.

That's what I thought as well, so I bought it, but it didn't work. I figure there must be another solution.

It didn’t work because the adapter in question converts digital optical to an analog line-level signal. Typically that won't drive headphones.

Your “other solution” can be found in Post #4.

The headphones in question are "active" and have volume control.

Isn’t the “active” part merely for the noise cancelling feature? I can’t see in the documentation that they also have built-in amplification. Until that can be confirmed, I’m sticking with my previous recommendation.

You may be correct. Why call it "volume control".

Line level outputs should provide some sound even with passive headphones, albeit low volume. Then your suggestion is quite right.

OTOH, perhaps there are some setup options in the TV that need to be adjusted in order for the optical to provide a signal (speakers off, PCM only, bitstream off).

Hm-m-m... quite similar to the device suggested in post #2.

Glad it worked out and thanks for the update!
