Exclusive Denon Technologies For Ultimate Sound Quality The AH–D310 features Denon’s Acoustic Optimizer system, which provides equal ambient air pressure on both sides of the diaphragm for naturally balanced sound. This exclusive technology inhibits resonance differentials for the smoothest and most natural tonal balance, especially in the critical midrange.
42mm Diaphragms With Neodymium Magnet Structure Equipped with large diameter 42mm diaphragms, the AH–D310 features powerful Neodymium magnets that provide extremely high efficiency for reduced power consumption, extending the battery life of your portable music player or computer. The large diameter contoured diaphragms exhibit resonance–free characteristics, all the way from the lowest lows to the highest highs.
Contoured Comfort Fit Headband For optimum comfort even over extended listening sessions, the AH–D310 features a contour fitted headband that provides the ideal combination of support and lightness, allowing enjoyable extended listening sessions with no fatigue.
