Ordering: To customize your IEMs, first you'll need to visit an audiologist for ear impressions. Then, you’ll need to mail those impressions to the Ultimate Ears lab. Your impressions must be received by November 23rd, or the offer will be null and void. After the drop ends, Massdrop will email each purchaser the shipment address and a unique order ID number, which must be included with the impressions you send. This is a “Bring Your Own Impressions” party, which means you can’t go to one of Ultimate Ears’ dealers with a scanner. Check this preferred audiologist map to find one near you.

Shipping: Orders are first come, first served, and the faster the impressions are sent, the faster you can expect to receive your IEMs. Ultimate Ears will provide free overnight shipping on all domestic orders. All international shipping will be done through Massdrop. Once impressions are received at the lab, your IEMs will be completed and shipped within 7 business days.
