Transductive earpieces

Transductive technology is the only transmission technology capable of guaranteeing covert earpiece users 100% interference-free communication.

Profilo Nano

The smallest and 100% interference-free covert earpiece
The audio crackling and white noise caused by electromagnetic interference (EMI) from alarm systems, vehicles and other electronic circuits can easily lead to missed commands and in turn ruined covert operations. The same is true if your earpiece is so large and obvious that it is spotted by the target.
Profilo Nano by Phonak is the world’s smallest covert earpiece, and thanks to its transductive loop technology it is completely immune to EMI, ensuring you remain covert and never miss an incoming message

  • World’s smallest covert earpiece
  • Zero electromagnectic interference
  • Crystal clear audio
  • Choice of PTT and loop configurations (see Wiring)

Profilo Nano's wiring kits are compatible with most professional radios including the latest Motorola, Sepura and Hytera TETRA models. A special connector is also available for Phonak’s Bluetooth (BT) module, enabling Profilo Nano to be used with BT-enabled communication terminals.
Phonak earpieces are the result of several decades’ worth of hearing research and experience. This is why thousands of professionals around the world trust a Phonak in their ear.
