Triple Noise Reduction Technology Why do some riders feel that the M1-S PRO doesn’t perform well at high speeds? Please follow these tips to achieve optimal noise reduction at high speeds: 1. Ensure the headphone cable is fully inserted into the main unit port when you use it. 2. The boom mic picks up sound from the side with the arrow, and if the user doesn’t correctly align this side with their mouth, it will face the wind, significantly reducing the intercom's effectiveness. 3. The intercom volume is adjustable. If you find the volume too low, press the "+" button to increase it. Universal Pairing The universal pairing mode of the M1-S PRO allows it to be compatible with some other helmet intercom brands, but it may not be 100% compatible with all models. Some devices from other brands may no longer be compatible with the M1-S PRO if they’ve undergone software updates. Audio Cable The audio cable lets you communicate and listen to music/GPS simultaneously. If you want to listen to music while communicating with your teammates, go ahead and get it! If your phone doesn’t have a 3.5mm audio jack, please use a USB adapter. Superior Sound Quality Why is the sound quality of our speakers superior to other intercoms? 1. The included speaker (diameter: 40mm, thickness: 10mm) uses silk diaphragm material, high-quality bio-diaphragm, and a superior driver unit, providing sound quality and resolution that is twice that of other speakers. 2. This intercom features an excellent playback system, creating a realistic listening room experience, allowing you to enjoy music with CD-quality stereo sound. Even at high volumes, the audio remains clear from low to high frequencies.
