This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes.

Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.
