These headphones are comfortable to wear and come with three pairs of different sized ear buds to help you get the best fit. They also have a warm sound quality that's perfect for genres like jazz and folk. Vocals and instruments remain clear, natural and detailed in your mix. They lack an ANC system and rely on their passive features to help reduce ambient sounds. They won't block out most of the low rumble of a bus engine, but they do a good job of reducing office-wide noises like chatter around you and the hum of computer fans.
