The D-shaped earcups mirror the shape of the outer ear, so the cushion rests more evenly on it. The closed back and ultra-soft cushions isolate you from outside noise passively and keep the sound with the listener, so people nearby hear less of it. There is no electronic noise cancelling.
The UR23iK suit everyday listening with a phone or laptop when you also need to answer calls. The One Touch microphone saves you reaching for your phone, and at 131 grams they will not tire you. There is no battery and nothing to charge.
