If you're on a budget and need headphones for general use, Sony MDR-ZX110 is the more affordable option with closed-back design, providing some passive noise isolation. For an immersive music experience, the Koss KSC75 with its open-back design offers better sound quality and soundstage, but lacks in noise isolation and isn't suitable for noisy environments. Neither model supports wireless connectivity, and they both have poor mic quality, so they're not ideal for calls. The Koss is lighter and clip-on, which might be more comfortable for long sessions, whereas the Sony headphones are foldable, slightly enhancing their portability. Both are straightforward, wired options with dynamic drivers meant for basic listening needs. If active noise cancelling, durability, and call quality are important to you, you may want to consider investing in a different pair altogether. Give Feedback

"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."

"My opinion about Sony MDR ZX110 is they are the best budget headphones of Sony with top-class sound. Clear vocals, great bass, and balanced sound with low sound distortion. The treble could be sharper, but it's ok. 30 mm neodymium dynamic drivers give clear and precise audio, and an inline remote with a mic give decent call quality. Closed-Back Design also helps to improve sound performance."
