At Denon we believe you should feel the music, not your headphones. In a quest to provide the most comfortable, best fitting headphones, Denon’s engineers have studied over 4,000 pairs of ears from people around the world, to come up with a design that automatically accounts for the subtle differences in ear placement, ear canal size, head size and jaw depression. We know that fit and comfort comes from paying attention to the small details. Denon’s Urban Raver AH-C300 In-Ear headphones come with a multitude of ear tips to choose from so you can get the right custom fit. Choose from Comply™ Foam TX-400M ear tips, Silicon Ear Tips (XS, S, M, L), and Double Solid Silicon Ear Tips (S, M, L). To achieve an even more secure fit, Denon also includes silicon ear stabilizers (S, M, & L), which are designed to fit snugly inside the bowl of your ear. Other accessories included in the box: protein leather carrying case with detachable karabiner and ¼” gold-plated adapter jack.
