1 x C-216 Carrying Case

Features:

At work, home, or on-the-go, the AT-216 gives you a close-up on sound
With internal audio processing that emphasizes the frequencies that define speech intelligibility
Not only are FM systems the best way to improve signal-to-noise ratios to overcome the listening challenges of distance, background noise, and reverberations, FM systems also significantly improve the effectiveness of hearing aids and cochlear processors
The NTC-102 neckloop provides a wireless connection to hearing aids and ear-level cochlear processors equipped with a telecoil (T-switch)
Enviro-Mic Combines environmental sounds from the receiver's microphone with audio from the transmitter so that both sound sources are heard together
