I have used both the Sennheiser PXC450 which are active noise cancelling headphones and the Shure SE 215 which are in-earphones. The Shure by far is the one that I have used most for coding/running. It does take some getting used to and earwax is a problem (You need to clean it every month or so). However, the sound quality is incredibly excellent and it shuts down external noise in a way that active noise cancelling headphones don't. Also, I believe you can find deals online for a price less than what you quoted.
