Our 30 day Satisfaction Guaranty

Assuming all conditions are met, we will refund the price of the products returned. If you 
are doing a partial return, you will be refunded the cost to you of the individual products 
returned. We cannot refund shipping charges.

If you purchased a package system at a discount and are only returning some of the items 
in the package, your refund will be adjusted based on the retail price of the equipment 
you are keeping. In other words, if you return part of a package, you end up paying the 
non-package price for the parts of the package you keep. (Otherwise, people could just 
order packages and return parts of them in order to get a cheaper price. A good scam, but 
not very fair to us.)

Unless specifically stated otherwise, all HeadRoom purchases come with a 30-day satisfac-
tion guaranty in order to give you the opportunity to evaluate your purchases. We’re happy 
to provide such a policy, and want you to use it if you aren’t happy with a product, but to 
keep costs down we do have a few guidelines. (Don’t worry, the vast majority of returns 
are refunded; we just need to make our return policy one that’s fair to everyone).

Conditions of Our Guaranty

Products must be returned to us within 30 days of the date you receive the product. So make 
sure you try your purchase out right away! (It’s amazing how many people say they left the 
country for a while and didn’t have a chance to listen before they left.)

Products must be in “as-new” condition. This means that they are in pristine cosmetic condi-
tion, are functioning perfectly, and include ALL materials (plastic bags, warranty cards, tie 
wraps, and any other little bit or piece that came with the product). In other words, please 
send products back exactly as you received them.

If a product is returned within the 30-day return period, but is not in “as-new” condition, we 
will charge you a 15% restocking fee plus any labor and materials required to return the 
product to “as-new” condition.

Products returned to us after the 30-day period, or which require more cost to repair than 
the wholesale value of the product, will be returned to the customer without a refund.
