Welcome Note

With cutting-edge optics and immersive audio, Music Shield is the ultimate fitness companion. They are the first sports glasses with customizable tint, ensuring optimal visibility during your ride, run, or training. Simply slide your finger along the side of the frame to adjust the tint level—instantly switch from light to dark or anywhere in between. With integrated Bluetooth audio, built-in speakers, and microphones discreetly embedded in each temple, they deliver crystal-clear sound, allowing you to immerse yourself in music, podcasts, and audiobooks—all while staying aware of your surroundings. Music Shield is designed for sports and fits most faces securely right out of the box but they also come with a customizable nose piece to help you find the perfect fit.

We don't think you'll ever want to go back to "normal" sports glasses.

Enjoy!
