Over-ear headphones - good sound isolation, powerful sound. The over-ear headphones completely enclose your ear. The advantage of this design is good sound insulation and sealing against the outside. This ensures high sound pressure and therefore powerful, punchy bass. Annoying ambient noise is minimized and you do not have to turn up the volume too high to get a powerful sound. These headphones are therefore ideal for noisy environments or as a working tool in the recording studio and for DJs. Active Noise Cancelling (ANC) for undisturbed music enjoyment. Active Noise Cancelling lets you focus on your music, even in noisy environments: The microphones built into the headphones detect disruptive ambient noise and then generate a corresponding counter signal that makes the noise inaudible to your ears. This technology is much more effective than the headphones alone in attenuating external noise. No matter where you are, block out the environment and enjoy your favorite music completely undisturbed.
