Quick guidance

Because the K240 MKII is semi-open, it is best used in quieter rooms and is not ideal for noisy commutes or situations where sound leakage could be an issue. For accurate monitoring, keep volumes moderate and pair it with a clean headphone output from an interface, mixer, or amplifier for consistent headroom and detail.

1. What does “semi-open” mean, and why does it matter?
   Semi-open headphones blend some of the spaciousness of open-back designs with more structure than fully open models. You get a wider, more natural soundstage, but there can be sound leakage in and out.
   
2. Are these good for mixing and studio monitoring?
   Yes. The K240 MKII is widely used for monitoring and reference listening because it emphasizes clarity and separation, which helps you hear details in vocals, instruments, and dialogue.
   
3. Can I use them in public or for commuting?
   You can, but it is not the best match. Semi-open designs leak more sound than closed-back headphones and also let more outside noise in, so they perform best in quiet environments.
