Note: At checkout, you'll be able to customize a variety of features (see "Options" section below). For custom IEMs, you’ll need to visit an audiologist for ear impressions. After the drop ends, you'll be responsible for having impressions made and sending them to Advanced AcousticWerkes in Singapore (address will be provided). As CIEMs are a time-sensitive product to make in bulk, please expect longer lead times. 

Or, you can choose universal IEMs. As these are handmade to order with your desired features, please expect an 8-week turnaround and note we cannot accept returns. Also note that universal IEMs may not fit everyone, and they aren't covered by the refit guarantee. For this option, canals will be the same color as the shell.
