The Mackie MC-150 are closed-back, over-ear studio headphones offering passive noise isolation and extended low-frequency reproduction for singers, musicians, and DJs. Large 50mm drivers deliver a wide frequency response of 15 Hz to 20 kHz. The padded earcups and padded adjustable headband ensure comfortable wearing for long performances and sessions. For convenient storage and transport, the MC-150 headphones utilize a collapsible folding design, which enables them to fit neatly in the supplied soft carry bag.
