StreamLine Mic

Hands-free phone calls, music and more in premium stereo quality

With Signia hearing aids and StreamLine Mic, you enjoy the 4-in-1 experience:

A pair of hearing aids that deliver the sound that nature intended

The StreamLine Mic transforms your Signia devices into more than state-of-the-art hearing aids. They also become a hands-free mobile headset and wireless headphones that stream premium stereo quality from any Bluetooth device – mobile phones, PCs, laptops, and smart assistants like Alexa, Siri and Google Assistant.

Hands-free phone calls, music and more in premium stereo quality

You can accept phone calls without having to take the phone out of your pocket. You can even make calls using voice commands. While streaming sound from your TV into your hearing aids via our StreamLine TV accessory, you can instantly take calls without having to turn off the TV sound manually. Besides, you can stream the phone call into both of your hearing aids (in case you have two) which significantly increases the quality of your conversation.

A pair of wireless stereo headphones with highest streaming quality

This is the ideal solution if you would like to stream phone calls, music, audiobooks and more, directly into your hearing aids from any device with a Bluetooth connection, including via voice commands.

A remote microphone for the best speech understanding in the most challenging situations

StreamLine Mic also functions as a remote microphone to help you in challenging hearing situations, such as crowded meetings. You can stream a speaker’s voice directly into your hearing aids from a distance of up to 20 meters. As a result, you hear the speaker as clearly as if he or she were standing right next to you.
And with the Signia app, you can remotely control StreamLine Mic for maximum convenience.
