Unless specifically stated, all HeadRoom purchases come with a 30-day satisfaction guaranty. We
do this because we want to give you the opportunity to change your mind after you get to hear
the products you bought. We’re very glad to give you this option, and we want you to use it if you
aren’t happy with your purchase, but we also want you to be aware of the conditions under which
we can provide you this guaranty:
·

Please return all packages to 2020 Gilkerson Drive, Bozeman, MT 59715

·

Assuming all conditions are met, we are willing to refund the entire purchased amount

for products returned.  We do not refund shipping charges.
·

If you are experiencing trouble with a headphone amp or a headphone system, please

email Sales at [email protected] to troubleshoot the problem.  This can save all of us
considerable time, effort, and money.
·

If you are doing a partial return, you will be refunded the cost to you of the products

returned.  If you purchased a package system at a discount and are keeping 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, we don’t give full-price refunds on products purchased at a discount.
·

If you are doing a partial return and exchange for other product, you will be eligible for

all discounts that would apply to the set of products that you end up keeping.
·

Products must be returned to us within 30 days of the date you receive the product. SO

if you think you might want to return something to us, listen right away; it’s amazing how many
people say the went out of the country and didn’t have a chance to listen before they left.
·

Products must be in as new condition. This means that they are not only in pristine

cosmetic condition and functioning perfectly, but that they are repacked with ALL materials (plastic
bags, warranty cards, tie wraps, and ANY other little bit or piece that came with the product) just
as you received it.  Please use the original  box it was received in (or another that is  compa-
rable); and please don’t send your headphones back in JUST the headphone box!
·

If a product is returned within 30-days, 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.
·

Return packages shipped to us must be sent “signature required” and insured, other-

wise they are sent back at your own risk!
·

Products returned to us after the 30-day period, or which require more cost to repair

than the wholesale value of the product will simply be returned to the customer.

We want you to know that we’re not hard cases about this; the vast majority of returns are

refunded.
