Listen to your favorite songs—and only them—when you put the Key Series T18NC Hi-Fi Earbuds in your ears. Using active noise-canceling technology, these high-fidelity earbuds block out unnecessary sound. Moreover, they use active noise reduction and dual microphones to contain the sound you want to hear and block out the world. Coming in a cool, circular charging case, these noise-canceling earbuds turn on when you slide open the lid. You're then ready to put the ear tips, which come in three different sizes, in your ear. Thanks to their 13-millimeter speaker drivers, these ANC headphones produce clear notes. Playing up to seven hours of music on a single charge, the included case offers an additional 17 hours. Simply tap the earbuds to play, pause, and answer calls. And when you're ready to change the track, all you have to do is tap twice.
