The red and white are for sound. The yellow is for video.

If you only have the red, white and yellow on the back of the TV and no 3.5mm headphone jack, you're going to want two things

1. RCA y-adapter to 3.5mm headphone:

That will allow you plug into the red and white for the audio and then have a regular headphone jack for headphones. The yellow is for video so you don't need to plug into that because you're going to use the TV for that.

2. Some regular headphones with a long cord:
The headphones on this list will work

Important note. I looked up Sceptre TVs and they generally have the headphone jack on the back of them. This is important because it saves you the cost of the adapter. Equally important though, is when you plug into that jack the sound will only be thru the headphones. Not thru the TV's speakers.

If you go the way of the RCA adapter and headphones the TV will still continue to produce sound from its built-in speakers. This may be a plus for you if you want to have guests over and they want to watch TV with you. They would be able to hear the sound from the TV's speakers and you would still be able to use the headphones to hear better at the same time.

I hope this helps.
