I was going to order the B&W Px7 s3 yesterday. It's $599. Costco has the Px7 s2 for $378 so I ordered that instead. I do like the Costco warranty.
Based on the reviews the sound for music is great but the ANC isn't as good as Sony or Bose. I however don't like ANC and I like that with the Px7 you can turn it off completely.
