Factors affecting the quality of the audio transmission from the earpiece in the extension

• The quality of the microphone used - if the quality of the audio input to the listening module is not sufficient, you will never get good results again. That's why we use Knowles' low-noise microphones with built-in preamps, which are among the best in the world.
• Microphone placement - even the best microphone placed in an extension cord will turn a call into an unintelligible murmur. Therefore, the microphone in our extension is pulled out into a miniature, pre-drilled hole, which ensures very good intelligibility.
• Network Interference - If an integrated power supply circuit is used in the headset, the sound quality will be degraded due to network interference. That's why we use an external power supply circuit that completely eliminates interference.
