Your Soundtastic Aria Hearing device combines the latest in hearing technology with a new Bluetooth feature that allows you to easily connect your Aria device to your mobile phone through the new Aria Connect phone Application. This easy to use Aria Hearing device not only uses the most advanced components to deliver you quality amplified sound, you can easily tune your device to exactly what your environmental setting is through the touch of your mobile phone. By using Soundtastic's Aria Connect phone app, no one will notice that you're even wearing the Aria, since you no longer have to discreetly touch your ear to adjust the volume or tune the device to your hearing needs. If you're not using your mobile phone, you also have the option to easily adjust your device with the rocker volume and memory control buttons located on top of the device. The Aria delivers 4 situational settings, a 4-channel compression processor and a 12 band graphical equalizer, delivering a truly natural listening experience in any environment.
