We ship as fast as we can. Sometimes demand exceeds supply. If that happens, here is what we commit to:
We believe in transparency. If there is a delay, we will tell you why, give you an updated timeline, and give you the choice to wait or receive a refund.
We stand behind our product. If you are not satisfied with your High Frequency headphones for any reason, you may return them within 30 days of delivery for a full refund of the product purchase price.
The 30-day window begins on the date your order is delivered, as confirmed by the shipping carrier's tracking information. Not the date you ordered. Not the date it shipped. The date it arrived at your door.
