If you're looking for top-notch sound quality and are willing to invest more, the EPOS PC38X could be a better pick given their higher sound quality scores and superior microphone quality, making them excellent for gaming, calls, and meetings. They are comfortable over-ear headphones with an open back for natural sound but offer little noise isolation, so they're not ideal for noisy environments. On the other hand, the Koss KSC75 are more budget-friendly and offer good sound quality for their price. They're clip-on headphones that are smaller and more portable but less suitable for activities like calls and gaming where microphone quality is important. Both are wired and lack active noise canceling, so neither will block out ambient noise effectively. The PC38X is significantly heavier than the KSC75, which may affect comfort during longer listening sessions. Give Feedback

"Lightweight and comfortable design, Mic arm with mute, Excellent tuning, Highly natural midrange voicing, Clean and separated bass, Solid soundstage dimensions. Combining all day comfort and integrated coms with a balanced and spacious sound from essentially any source, it is hard to deny the versatility and value provided by the PC38X."

Crinacle | June 2022
"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."
