The Naída is a behind-the-ear (BTE) device with a BTE speechprocessor, a battery-compartment and a coil with magnet. Available in several colours (click here for colour palette).
There are several off-the-ear options for a lighter weight wearing style. The battery can be detached from the BTE to be worn on the clothing. Or the entire processor can be worn off-the-ear.
Alternatively, the battery compartment can be replaced by a connector with a body-worn battery box with AAA batteries("powerpak").
