The Monster Beats by Dr Dre, black in color, boast choice sound isolation features for the best possible music-listening experience for the user. The thick foam, which is washable, surrounding the ear cups on these Monster Beats headphones shuts out external noise and highlights bass frequencies, without using any noise cancellation frequencies or other amplifications that might add distortion to the sound. These high-definition headphones have dual input/output cable ports, which allow users to plug their headphone cables into one earcup, while the other port automatically switches to output mode. The earcups of these Monster Beats by Dr Dre can each be flipped up off the user’s ear to better hear sounds from the environment, or the user can push the mute button integrated onto these Monster Beats headphones without removing them. The folding design of these high-definition headphones makes packing up a breeze.
