Sporting Varimotion 30 mm XXL transducers, the K141 MKII boasts near startling sensitivity and a wide dynamic range. Meant to be worn as studio cans or for reference purposes, the lows, mids, and highs are all in line where they should be and nothing stands out to the detriment of the overall sound. With the semi-open design, the soundstage is expanded to include more width and depth and they remain comfortable for extended sessions.
