C4220 Handset Design
Earpiece Shape
The earpiece is shaped
specifically to cup the user’s ear,
accomplishing a “custom fit”
experience.
Not only comfortable, but
functional. The “cup” forms a
sealed chamber around the ear for
better sound. This enables the
phone to work extremely well with
a hearing aid, reducing
background noise and feedback.
