If you're looking to get the best possible audio experience when watching television without raising the volume a pair of television headphones can be the most immersive experience imaginable. A closed back design is handy if you want to prevent the audio you are listening to from leaking out and disturbing those nearby. Starting at under £50, wireless TV headphones are very convenient if you want to be without the tangle of wires. Brands such as Sennheiser and Thomson produce headphones designed specifically for TV with extra long cables and volume controls built into the cord.
