What they are. How to order.

Custom In-Ear Monitor (CIEM)

The Custom In-Ear Monitor (CIEM) is a set of earphones crafted using custom-moulded shell to fill exact cavity of your ears. The CIEM process begins with getting an impression of your ear canal from your local audiologist, and sending the impression to us.  We then carefully craft the monitor shells mirroring the shape of your impression using the medical-grade acrylic.  Delicately tuned and matched drivers are then mounted into the shells to create a bespoke earpiece built just for you.  The entire process takes about 4-6 weeks after your impression is received.

Custom-fit Ear Tips

The Custom-fit Ear Tips are a set of silicone ear tips that are made to work with universal in-ear monitors to provide ultimate noise-isolation and maximum comfort.  The process begins similarly with the impression of your ear canal, however, it is built with medical-grade silicone material that is flexible, yet rigid enough to provide comfortable and fully isolating seal. Each custom-fit ear tip is then coated with antimicrobial UV coating for prolonged product life-cycle of up to 7-years.  They are made proudly in the USA, with shorter lead-time of 2-3 weeks after your impression is received.
