Know before you buy
Because these are semi-open back headphones, they allow sound to leak in and out. They are excellent for mixing and mastering, but they are not recommended for tracking vocals or instruments, as the sound may bleed into your microphone.
Yes, with an impedance of 55 ohms, these headphones can be driven by most standard laptops and mobile devices. While they will work fine, using a dedicated headphone amplifier can help you get the most out of their dynamic range.
Yes, the ear pads on the K240 MKII are designed to be user-replaceable. This is a standard feature for professional studio gear, allowing you to extend the lifespan of your headphones significantly.
The semi-open design provides a more natural, spacious soundstage that mimics the experience of listening to speakers in a room. This makes them ideal for critical listening and mixing, though they offer less noise isolation than closed-back models.
The headphones use a professional mini-XLR connector to attach to the ear cup. This ensures a secure, reliable connection that is easy to swap out if you prefer the included 3-meter straight cable or the 5-meter coiled cable.
The self-adjusting headband is designed to distribute weight evenly across your head without requiring manual adjustments. Combined with the lightweight 240g frame, it is widely considered one of the most comfortable designs for long editing or mixing sessions.
