KZ ZS10 PRO 2 vs KZ ZS10 PRO X: Which One Should You Choose?
Two of KZ's most popular hybrid earphones, both with the classic 5-driver configuration (1 dynamic + 4 balanced armatures per side). But they take different paths: the ZS10 PRO X focuses on improved treble and a brighter sound, while the ZS10 PRO 2 offers customization with a 4-level tuning switch. Here's what actually changes.
KZ ZS10 PRO X — Enhanced Treble and Updated Design
The ZS10 PRO X is the direct evolution of the legendary ZS10 PRO, one of the best-selling earphones in KZ's history. It keeps the 1DD + 4BA hybrid architecture but with updated balanced armature drivers — the new 50024s — which improve treble processing, delivering a wider soundstage and greater detail in the high frequencies.
The cable is flat and silver-plated, which reduces the microphonic effect (that rustling noise when the cable touches your clothes) and improves durability. The ergonomic design with a metal alloy faceplate and resin cavity keeps the classic look with robust construction.
How it sounds: Brighter and more detailed than the original ZS10 PRO. Treble gained presence and clarity with the new drivers, bass remains powerful and engaging thanks to the dynamic driver, and mids stay well balanced. It's a vibrant sound that works well with any genre, especially those that benefit from defined highs — pop, rock, gospel, country.
Best for: Those looking for a direct upgrade from the original ZS10 PRO, musicians who value treble sparkle and detail, and anyone who prefers an earphone that comes ready to go without needing adjustments.
KZ ZS10 PRO 2 — Customization With a Tuning Switch
The ZS10 PRO 2 takes a different approach. Instead of simply upgrading the drivers, it adds a 4-level tuning switch that lets you customize the sound profile. Want more bass? Adjust. Want to bring vocals forward? Adjust. Want brighter treble? Adjust. It's a level of control that no other KZ earphone in this price range offers.
The 10mm dynamic driver handles bass and mids, while dual 31736 balanced armature drivers take care of the highs and ultra-highs with precision and transparency. The frequency range spans 20Hz to 40,000Hz. The build follows the same standard — lightweight metal faceplate with a comfortable resin cavity.
How it sounds: It depends on how you configure it. In the neutral position, the sound is balanced and detailed, with powerful bass, smooth mids, and precise treble. But the real advantage is the ability to adapt: if the rehearsal room has too much reverb, you compensate. If the genre calls for more bass, you boost it. It's like having multiple earphones in one.
Best for: Musicians who play in varied settings and need to adapt their sound, those who enjoy having control over their sonic profile, audiophiles who like experimenting with different configurations, and professionals who want a versatile IEM for both stage and studio.

The Difference In Practice
The ZS10 PRO X gives you a ready-made sound — bright, detailed, with treble up front. You put it in your ears and the sound is already dialed in. The ZS10 PRO 2 gives you the power to decide how you want to hear. In the neutral position, it sounds balanced and precise. Flip the switches, and you adapt to each situation.
If you're the type who wants to plug in and start playing without thinking about configuration, the PRO X is more straightforward. If you like having control and adapting the sound to the context — type of gig, acoustic environment, musical genre — the PRO 2 gives you a flexibility the PRO X doesn't have.
