Go anywhere with the protective case

The Chorus Protective Case lets you enjoy waterproof hearing. You can now hear and stream music while swimming and go anywhere with lots of water, mud, and dirt.

Chorus also comes with a clip that gives you easy access to the controls. You can even detach the battery without removing the clip.

Excellent speech understanding in noise

"My favorite Chorus feature is the Roger system and the compatibility to connect with Bluetooth devices. Also being able to connect with music via a Bluetooth device and the flexibility of having a waterproof kit for pool time with the family."

– David Cluff, Website & Digital Marketing Consultant
