The Crystal Mic Pro XS, designed by OSEI Aviation—renowned as a leader in aviation products for both students and professionals—is a top-tier aviation microphone attachment compatible with WH-1000XM4 and WH-1000XM3 headphones. It features the M7A2 microphone, which matches the size of the David Clark M7A, providing a compact and effective solution for clear cockpit communication.

This versatile attachment can be connected to either side of your headphones, allowing you to choose the microphone placement that best suits your needs. It also comes with a robust volume control unit that includes two auxiliary inputs, enabling you to connect your phone for music playback (though not for making calls). The Crystal Mic Pro XS is equipped with a thick, sturdy mic boom that remains securely in place, eliminating the floppiness found in some competitors' models. This attachment is the perfect choice for aviators seeking a high-quality, reliable communication tool that seamlessly integrates with their existing headphones.
