Tivoli Audio Radio Silenz headphones are the company’s first headphone effort and also the world’s first active noise canceling headphones containing wood ear cups. With high performing 40mm drivers, a “Defeat” button that fades audio and momentarily stops the cancellation, allowing you to hear your surroundings, battery life up to 50 hours from a single AAA battery and noise cancellation up to 85%, what more could you possibly want? A choice of colors perhaps? Tivoli makes that possible too, since the collapsible Radio Silenz headphones are available in your choice of cherry, black ash or walnut, along with a convenient travel pouch for storage when not listening to your tunes.
