It's been a while since Willy Wonka set London on a hunt for five golden tickets, so Sennheiser thought they'd bring it back, bigger and better, with 500 “Golden Ears" hidden in music-friendly venues around the city. All you have to do is track them down using the clues on the Let Your Ear's Be Loved website and cash them in for a pair of Sennheiser Urbanite headphones. Finders-keepers can exchange Golden Ears at Westfield London or Westfield Stratford City. The hunt is on from October 21st to November 2nd, so get scavenging. Don't live in London? You can still post an "ear selfie" on Instagram for the chance to win free headphones.
