Sennheiser HD 419 Over-Ears for $30

The closed-back Sennheiser HD 419 over-ear headphones are currently on sale in new condition for $30 at Groupon Goods. Free shipping over there (just like Amazon and Best Buy) with a $34.99 or higher purchase. You can reach the amount with multiple items (also multiple different items as well) as long as they all ship from Groupon warehouses and not directly from vendors.

Amazon has not fully price-matched them, their price is $33 with a limit of five.
