Sony MDR-NC6 Foldable Noise Canceling Headphones in Corded Headphones

These are the best affordable noise cancelling headphones I've used. Fantastic on BART or public transit! Reduced a significant amount of background noise. Single AAA battery lasts for weeks with daily use (I use a rechargable).
