Heard them put into a room, then taken out. I was very sceptical, they made a difference. I can't explain it and no it wasn't placebo. The difference, improvement was large and obvious.

Those taking the piss, go listen to the item in the OP then come back and share a valid opinion based on actually hearing it. If you haven't heard then I would suggest keeping snide, derisory comments to yourself.
Santa obviously didn't deliver a sense of humour!
