When Taron and Andrew Lissimore started headphones.com, they wanted to create the headphone store they wished existed. As headphone enthusiasts, they wanted a store with 365-day returns.
So they decided they were going to try to make 365-day returns work - no matter how ridiculous it sounded to their wives.
Years later, they're still doing it, and their wives still think they're crazy.
So take some time to get to know your new gear. We want you to enjoy your purchase for years, not just a few weeks. If you're not satisfied, you can return items in like-new condition for up to 365-days.
How To Make a Return
1. Follow the link below.
To get the return process started, you just need to click this link. Enter your order number as well as e-mail address to get it started and after that just follow the steps outlined in the portal (note open-box, special order and sale items are not eligible). A pre-paid shipping label will be generated for you a deducted from your refund after being processed.
After receiving your return label, you will have 7 days to drop off your return with the courier. If your return is not dropped off within 7 days of receiving your return label, a 30% restocking fee will occur. If your return is not dropped off within a month of your label being issued, your return will be rejected.
2. Pack Your Items Carefully
Your item must be in like-new condition with its original packaging. It must also include all original accessories and manuals. Please add a larger shipping box to protect the original packaging during shipping.
Important Refund Details

You may choose either a refund or an exchange for the full cost of the item. The refund will be processed on the same method of payment you used to make the original purchase.

Return Policy Abuse
In order to provide a 365-day return policy, we need to take abuse seriously.
We monitor a buyers ratio of purchased to returned products. If it exceeds an internal threshold they will no longer be allowed to place orders with Headphones.com. This includes customers who spread returns across multiple accounts.
We made our return policy to help you find gear you feel great about for a long time. Most people use it exactly as intended. We don't want the handful of people who attempt to abuse our policy to ruin it for everyone else.
If you paid with a cryptocurrency, the returned amount will be equal to the USD equivalent of your payment on CoinGecko.com at the time the refund is processed. The return will be made in the currency of your original order.
After You've Made a Return
Each return is inspected at our warehouse. During busy times these inspections may take a few extra days.
Refund or Credit
We will notify you by email when your refund or credit has been processed. It may take a few business days for a refund to appear in your account. This is determined by your financial institution.
If you still have questions, please email firstname.lastname@example.org and an advisor will be happy to help.
One of the key things we pride ourselves on is our customer service and one of the most important aspects of our customer service is getting you your product on time! But not only do we want to get it to you on time, we want to make sure we are using a reliable courier so the experience for you is the best possible. That is why we ship all of our orders with FedEX.
While couriers like USPS are tempting because of their low cost, we have found that they are not a good experience for our customers. Nobody wants their package to not be delivered and then have to spend an hour on hold with the local post office trying to get information. To that end, all of our packages are shipped signature required with FedEX to make sure your package arrives in your hands safe and sound and if there are any issues, your time isn't wasted.
However, if you are looking to ship to PO Box or APO address, we can definitely accommodate your shipping needs!
How Much Does Shipping Cost?
Shipping in the continental US is free if your order is over $100, no matter what (you do always have the choice to upgrade your shipping at checkout as well).
Canadian orders over $250 are eligible for free shipping. Duties & Taxes are not included but you can choose to pay Duties & Taxes during checkout with DHL.
Due to our vendor agreements with the brands that we carry, we are unable to ship outside of the United States or Canada.
FedEX Ground Shipping
All orders $100 or over & under $300 qualify for free FedEX Ground shipping.
FedEX 2-Day Shipping
All orders between $300 - $999,99 get free FedEX 2-Day shipping.
All orders over $1000 qualify for free FedEX Overnight shipping. Overnight shipping is covered under FedEX as the next business day. Saturday and Sunday deliveries are not part of their guaranteed overnight delivery.
All orders shipped through Headphones.com are shipped with signature required. Since most signature requirements have been suspended during COVID-19, we are shipping orders with an Adult Signature Required.
How Soon Will My Order Ship
We strive for every item we have on the website to be in stock and ready to ship the same day. So if your order is in stock and you place your order before 1pm PST, it will ship that same day.
Sometimes, we like to give our customers the opportunity to place orders on backordered items or pre-orders. In those situations, it will be clearly written on the page that the product is backordered or available for pre-order. When the item is back in stock, it will ship out with the FedEX shipping methods above.
