Frequently Asked Questions (FAQ)

Custom In-Ear Monitors are made to perfectly fit into your personal ears and provide you two main benefits: to greatly reduce the noise levels around you (safer for your hearing), and to give you full control over your monitoring mix (to facilitate your performance on stage). We make our CIEMs to fit perfectly and you’ll forget about them and just enjoy the benefits of a great monitoring mix!

Our standard build time (from the day we receive usable impressions) is 2-4 weeks. If you have a specific date you need them by, please contact customer service.
