Custom Earpiece, now Black Diamond Radio, started in 2002 with a dedication to quality custom molded products and a commitment to customer service. Our radios use military grade aluminum chassis, not plastic. Our earpieces are Kevlar wired and have a shock resistant coil.

We have a 2 year “If You Can Break It, We Will Replace It” warranty on the radios. The earpieces and batteries are covered under the same warranty for 1 year!

Our policy is to treat you the way we would want to be treated. At Black Diamond Radio we do not have complicated menus on our phones. When you call a human answers the phone and attends to your needs! We go out of our way to make sure that you get what you need when you need it to ensure your workflow is interrupted as little as possible!

Our president, David Eames, created Black Diamond Radio in 2002 when he saw a need for high quality earpieces at a reasonable price. Eventually, that led to providing durable, top-notch two-way radios to business owners who wanted to take their company to the next level. 20 years later we have served over 17,000 customers nationwide!
