Yes, SONNET can easily connect to your phone using a wireless receiver and microphone, such as the Roger PenTM from Phonak. This allows you to make hands-free calls, with the sound coming directly to your ears. A wireless microphone also makes it easy to connect to tablets, TVs, and other devices, and to hear better in challenging environments.

Alternatively, SONNET can be used with Bluetooth neckloops, and connects to hearing loops in public spaces, such as theatres or airports. You can also connect to your devices using a direct audio input cable.
