I would like to use my headphones to listen to my tv in my bedroom. 
 
The tv do not have a 3.5mm output. It has rca output and optical output, that's all.
 
What is the cheapest way to use my headphones?
 
I have a spare home theater amp but it's way too bulky.

Something like this should do if you want cheap.

What headphones?
 
Fiio E17 (DAC/Amp) comes with an optical input, sometimes goes on sale for around $105.
 
PAV2V (Pocket Amplifier 2 Version 2), sells on eBay for around $60.
 
Optional
A Fiio D3 optical input DAC ($28) can be used with the PAV2V headphone amplifier.
