You don’t need to sell a kidney to afford noise-cancelling Bluetooth headphones; these 4 star-rated Cowin E-7s are just $39 right now, or $31 off with promo code K8WP23JH.

They might not have the brand recognition of Sony or Bose, but these headphones pack in 30 hours of battery life, the ability to use them in wired mode if the battery dies, and yes, active noise cancellation that reviewers say works really well.
