Enjoy music and conversations without distractions with the Gemini Noise-Canceling True Wireless In-Ear Headphones from Devialet. The embedded active noise cancellation technology can filter out distracting sounds as you listen, and is automatically activated when you receive a call, helping you be heard clearly while on the go. An included charging case delivers enough power for all-day entertainment, which can be tuned and adjusted via the Devialet Gemini app. The app can also assist in making the earbuds comfortable by helping you determine exactly which of the four pairs of eartips are best for your ear shape.
