Mackie MC-350 Closed-Back Studio Headphones with 50mm Drivers and 3 Cables

Mackie MC-350: Closed-Back Reference That Tracks and Mixes

The Mackie MC-350 is a professional closed-back studio headphone built around 50mm dynamic drivers that pair a precision-tuned sealed enclosure with genuine-leather comfort to deliver punchy, detailed sound for both tracking and mixing. Its sealed earcups block bleed at the microphone and shut out the room, while three detachable locking cables and a protective case make it as ready for a location shoot as for the mix room. For the engineer who wants one pair of phones that can handle the whole session, the MC-350 is the closed-back that quietly earns its place on the hook.

50mm Drivers in a Precision Sealed Enclosure

At the core of the MC-350 sit 50mm dynamic drivers voiced inside a closed-back enclosure that Mackie tuned for tight low-end punch and enhanced high-frequency detail. The sealed design gives the bass a solid, physical foundation you can feel while keeping the upper mids and treble clear enough to place every instrument and voice in the mix. Rated at 32 ohms with 97 dB sensitivity across a 20 Hz to 20 kHz range, the MC-350 reaches full level from an interface headphone jack, a console cue bus, or a portable recorder without a separate amplifier.

Closed-Back Isolation for Tracking Without Bleed

The reason a vocalist or drummer reaches for a closed-back headphone is isolation, and the MC-350 delivers it two ways at once. The sealed cups keep the click track and backing mix from leaking into an open microphone just inches away, so takes stay clean and phase-coherent. At the same time they block enough outside noise that a performer can hear pitch and timing clearly on a loud stage or in a busy tracking room. That same seal is what lets the MC-350 double as an accurate mixing tool once the record button is off.

Three Detachable Cables and a Locking Connector

Every MC-350 ships with three cables that attach through a secure bayonet-locking connector at the earcup, so a yanked cord pops free or swaps out instead of destroying the headphone. A 3m fabric-covered straight cable reaches from a patchbay to a vocal booth, a 1.2m straight cable keeps things tidy at the desk, and a 1.2m cable with an inline microphone and volume control turns the MC-350 into a headset for calls and mobile listening. A gold-plated screw-on adapter steps the 3.5mm plug up to a 1/4-inch jack for studio gear.

Genuine Leather Built for the Long Session

Long sessions punish cheap headphones, so Mackie wrapped the MC-350 in real leather at both the conforming earpads and the adjustable headband. The leather earpads seal gently around the ear to support the closed-back isolation while spreading clamping force so the phones stay comfortable through a full tracking day, and the leather-faced headband resists the cracking that plagues plastic bands over years of use. The result is a headphone that feels as durable as it sounds, ready for daily studio and location duty.

Who the MC-350 Is For

Recording engineers, producers, podcasters, and musicians who need one closed-back headphone for both cutting takes and checking a mix choose the MC-350. It isolates a vocalist tracking to a click, keeps a drummer locked to the tempo, gives a podcaster clean monitoring on location, and then translates accurately enough to trust for editing and mixing. When the open-back MC-450 is the mix-room specialist, the MC-350 is the versatile closed-back that goes everywhere the work does.
