What I didn't realize last week (and my apologies if you didn't catch this yourself) is that there's an Android-specific version of the product. It's also $124.98, minus $10 with code TEN4U.
If you've never used headphones that have active noise-canceling capabilities, you're in for a treat. On trains and airplanes, engine roar drops to a barely-there hum.
