UNBOXED

Headphone Zone Certified Unboxed Units

Unboxed units are as good as new products with the product's packaging being unavailable. These products give you the same satisfaction of new products - but at down-to-earth prices. Usually, the product's packaging may have gotten damaged in transit. Customers use a product once or twice and then return it with opened up packaging.

WHERE DO UNBOXED PRODUCTS COME FROM?

Customer Returns
Returned headphones are fully functional products that have left the warehouse and therefore can no longer be sold as new as their packaging has been opened. The product may have been used once or twice by the customer who returned it.

Transit Damages
Sometimes we receive headphones in damaged packaging due to shipping accidents. These are brand new headphones with cosmetic flaws on the packaging.
