Cowin E-7 Noise Canceling Bluetooth Headphones | $11 | Amazon | Use promo codes CBDEAL11 and M8TUC9ZO

Update: Sold out, it seems. Hope you got a pair, and hope it ships!

~$30 discounts come around pretty often on Cowin’s crazy-popular noise canceling Bluetooth headphones, but today, you can actually stack two of those discounts to get the set for just $11. First, use promo code M8TUC9ZO at checkout to save $28, then put in code CBDEAL11 to take off an additional $31.

Are they as good as Sony’s noise-canceling headphones? No, of course not, but they boast 30 hours of battery, and offer solid value for anyone on a budget.
