AKG K240 MKII: The Studio Classic

Semi-open headphones let some air pass through the earcups, producing a more natural, speaker-like soundstage than closed designs. That makes the K240 MKII a favorite for mixing, editing, and long listening sessions where accuracy and comfort matter.

Comfort for Long Sessions

The self-adjusting headband automatically fits a wide range of head sizes, and two sets of earpads let you choose between leatherette for isolation and velour for breathability.

Setting Up the K240 MKII

Attach the straight cable for desk work or the coiled cable for flexibility while moving around. Connect the 3.5 mm plug to a laptop or portable device, or screw on the 1/4-inch adapter for audio interfaces, mixers, and headphone amps. Start at a low volume and raise it gradually.

What to Pair With the K240 MKII

Pair the K240 MKII with an audio interface or headphone amplifier, a headphone stand, a protective case, and studio monitors for cross-checking mixes.

Semi-Open vs. Closed

Semi-open headphones like the K240 MKII offer a more natural sound for mixing, while closed headphones isolate better for tracking near microphones. Many engineers keep both types on hand.

Replaceable Parts

Detachable cables and replaceable earpads keep the K240 MKII working for years, and spare parts are easy to swap when they wear out.

Where to Use It

The K240 MKII suits mixing and mastering, podcast editing, broadcast monitoring, music practice, and classrooms where comfort over long periods is important.

Choosing Earpads

Leatherette pads provide a little more isolation and bass, while velour pads stay cooler and more breathable during long sessions. Swap them to suit the task, or keep one set as spares.

Mixing Tips

Use the K240 MKII alongside studio monitors, checking mixes on both. Keep headphone volume moderate to avoid ear fatigue, take regular breaks, and reference commercial tracks you know well to calibrate your ears.

Care and Maintenance

Store the headphones on a stand or hook to protect the headband, wipe the earpads after use, and replace worn pads and cables as needed to keep them performing like new.
