Studio-Quality Monitoring When the studio is your thing, and you need to study every detail of a mix, Roland?s RH-200 headphones belong in your control room. Comfortable and light enough for all-night sessions, the RH-200?s closed-back design shuts out external noise and lets you dive into the mix or focus on your performance. With 40mm drivers, neodymium magnets and CCAW (copper-clad aluminium wire) voice coils, the RH-200 offers clear, accurate and natural response, letting you assess everything from stereo image to low end ? and always make the correct decision. That level of clarity also makes the RH-200 the ideal choice for other musical scenarios, from practicing your instrument to streaming your latest playlists.
