Tamperproof Design
SONNET 2 EAS is tough enough for even the most curious toddlers. Both the audio processor and the coil are fully lockable, keeping them safely in one piece, and are optimally sized so they can't be swallowed by children.
Audio Processor Check
Check your child's audio processors are working correctly. The link-check function lets you see at a glance if your child's SONNET 2 is attached to the coil correctly. And you can check if their microphones are working properly using the FineTuner Echo Remote Control.
Wearing Options
SONNET 2 EAS’s wearing options make it lighter to wear for little ears. BabyWear and ActiveWear allow you to attach some or all of the audio processor to your child’s clothes, so that they can enjoy comfortable hearing all day long.
Fixation Options
Keeping audio processors on your child can be a challenge! With a wide range of convenient fixation options, your child can wear SONNET 2 EAS all day long.
Small Size
Choose the Micro Rechargeable Battery for your child’s SONNET 2 EAS, and give them one of the smallest and lightest audio processors available.
AudioKey 2 App
The AudioKey 2 app contains a special “Guardian Role” feature, so you can control your child’s audio processors from your phone. In addition, you can check their hearing stats and make sure they are getting the most from SONNET 2 EAS.
Long-Lasting Power
SONNET 2’s powerful batteries mean you can go for days at a time. Choose regular zinc-air disposable batteries for the longest wearing time. Alternatively, the rechargeable batteries are a convenient way to keep SONNET 2 powered up throughout the day.
