Recommended amp for headphones?

[Moorbs]

The new TV I bought (Samsung UE60KU6000) only has digital out so I'm buying a digital to analog converter but then I need to amplify that signal for volume control with my headphones.

Can anyone recommend a cheap amp to do this? I'm in the UK, the Behringer HA400 is the cheapest I've found but it's around £20 and requires a couple of adapters for 3.5mm.

In case anyone finds this post and wants an answer I ended up buying this https://www.amazon.co.uk/Avantree-Digital-Converter-Adapter-Headphones/dp/B01LMXXHA8 which has optical in and aux/ rca out with an amplifier and volume control. Very useful if you bought a Samsung TV without a headphone jack.
