Hands-Free Functionality for the HELIX BT HD STREAMER
The BT HD Hands-Free Microphone Kit is the perfect addition to the BT HD STREAMER and enables seamless integration of a convenient hands-free functionality with superior audio quality, without the need for any modifications of the head unit.

Voice-optimized Frequency Response
The microphone features an optimized cardioid polar pattern for clear voice recordings. This is specifically designed to precisely capture the driver′s voice while effectively reducing ambient noise for crystal-clear communication during the drive.

Echo Cancelling and Noise Suppression Technology:

Noise Suppression (Noise Cancelling): The algorithm in the BT chip of the HELIX BT HD STREAMERS filters out background noises such as vehicle sounds and road noise, enabling clear communication during driving.
Echo Suppression: This function prevents echoes during the conversation by minimizing the audio feedback between the speaker and microphone, improving the sound quality of the conversation.
Voice Enhancement: This optimizes the driver′s voice recording by improving the clarity and intelligibility of the voice and reducing background noise. In addition, the automatic volume correction adjusts differences in conversation volume, making even distant persons easily understandable.
Convenient Control Options
For the specialist dealer or experienced DIY installer, the included cable set enables the connection of ″optional buttons″, allowing important functions such as ″track forward″, ″track back″ and ″accept call″ or ″reject call″ to be controlled externally. It also offers easy pairing of new smartphones for maximum flexibility and convenience.

Made in Germany
The microphone is manufactured with the highest precision and quality in Germany. This ensures that you receive a product that meets the highest standards and provides outstanding performance.
