Product description
The ReSound Unite® Mini Microphone transmits
speech directly to your patient’s hearing instruments from a range of up to 20 feet. It is:
• Small
• Lightweight
• Portable
• Wireless
Easy to connect
• Easy to wear (clip on or wear with lanyard)
• Just press the pairing button on the ReSound Unite
Mini Microphone, then open and close the battery
door of the hearing instruments within 20 seconds and
it automatically pairs with the hearing instruments
The ReSound Unite Mini Microphone optimizes
signal-to-noise ratio in person-to-person communication. It sends a speaker’s voice directly
into your patient’s hearing instruments without
the need for any extra devices—no cables,
cords or necklaces. It is effortless, reliable and
improves speech understanding in difficult
listening situations where distance, background
noise or poor acoustics is an issue. And since
the listener is not required to look directly at
the speaker during a conversation, he or she is
free to perform dual attention tasks that normal
hearing people take for granted.
In essence the ReSound Unite Mini Microphone
extends the hearing range well beyond the reach
of any hearing instrument in a variety of situations, such as when having conversations:
• At home
• In the car
• While dining out
The ReSound Unite Mini Microphone also functions as a portable audio streaming device. Via
its plug-and-play line input connector, the user
can connect to virtually any audio source, e.g.,
MP3 player, computer, phone, or even TV, to
stream audio directly to the hearing instruments.
It is ideal for situations such as:
• Pairing can also be done through the ReSound
Aventa® 3 fitting software
• One-time pairing procedure—once paired the
ReSound Unite Mini Microphone will stay paired with
the hearing instruments
