If you prioritize gaming, calls, meetings, or music production, the EPOS PC38X offers best-in-class microphone quality, excellent sound, and an expansive soundstage, making it worth the higher expense. However, its open-back design and size make it unsuitable for outdoor use and workouts, as it doesn’t isolate noise well and isn't portable. The KZ ZSN Pro X is more budget-friendly, providing good sound quality and better portability, suitable for general music listening and commuting. Although it has a high build quality, the in-ear comfort and microphone quality are not as high as the PC38X, and it lacks features like wireless connectivity and active noise cancelling. Choose the EPOS PC38X for dedicated, high-quality home use, especially if gaming or clear communication is important, or the KZ ZSN Pro X for a more affordable, versatile option that’s easier to travel with.

"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."

"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."
