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-C100BU 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 or Silicon Ear Tips (S, M, L). A diminutive carrying case is also included for extreme portability.
