The crackling and hissing in the ear caused by electromagnetic interference (EMI) from alarm systems, vehicles and other electronic circuits can quickly lead to unclear communication and, in the worst case, can cause undercover investigations to fail. Similarly, failure can also result from a large and obvious earpiece being spotted by a surveillance target.
Profilo Nano by Phonak is the world’s smallest in-ear receiver for covert communication. Thanks to its transductive loop technology, it’s completely immune to electromagnetic interference, ensuring you won't be noticed or miss any transmissions.
- Smallest in-ear receiver
- Absolutely immune to electromagnetic interference
- Crystal-clear sound
- Selection of PTTs and induction loops
Profilo Nano headsets are compatible with a wide range of professional radios (including the latest TETRA models from Motorola, Sepura and Hytera). Phonak’s in-ear receivers are the result of decades of hearing research and experience. That’s why thousands of professional users around the world trust us.
