If your Discover D904 headband has been lost or broken, the D425 is a direct replacement. Adjustable for fitting different size heads and a leatherette ear cushion included. Quick and easy to set up, the D425 will have you talking before you know it.
I'm pleased that these replacements were available at a reasonable price. My staff tends to be hard on their headbands, so this was necessary. They also seem to prefer the headband to the earpiece for comfort.
