Purchased on Mighty Ape

Has a design feature where the audio cuts out to static if the headphones don't detect a certain volume for a certain period of time – it's designed to save the battery life but it's really annoying when you're watching a film with a lot of atmos and suddenly your ears get blasted with static. Also picks up a lot of interference even when you're close to the headphone hub. Spend a bit more money on a better model or stick to wired.
