There £20 actually (just checked), and these are better then your typical Amazon Basic / Generic cable as I have shown in that video above, they are made from Van Damme studio cable. He will need a 3M cable pair anyway that would be £10 even for a generic, so we are talking a £10 difference! He does have what was a £200 retail sound card.
You can get decent copper cables for a fiver for the lengths he's probably needing.
