KZ ZST PRO X Dual Flagship Drivers In Ear Earphones Deeper Bass HiFi Headphones Dual-Driver Synergy Detachable Cable Headset

The box was crushed, but everything inside is intact. Compared to previous models, the sound quality has improved.

These really improve the sound from older KZ sets, having a better overall clarity to the set, more upper treble while also keeping the bass. The soundstage and imaging is alright too. Overall for $20, these are an absolute steal, and the design looks modern over the older design too.

Since it was a Choice product, it arrived within a week. Earphones with clear sound, with a nice balance of bass and treble.

The metal faceplates look good but the clear plastic shells and excess glue? are ugly. Soundwise, I've never been satisfied with anything's default sound and always use EQ, but the ZST Pro X's default bass is actually kinda impressive. It's still not to my liking but I get why Jaytiss gave it a 6 and not a 5, 4 or 3 like the typical B tiers on his ranking list. Anyway, with my preferred NiceHCK C04 eartips and personalized EQ profiles, the ZST Pro X sounds like a slightly louder, slightly thumpier ZVX Pro. The ZVX Pro sounds cleaner, snappier and has better delicacy and dynamics. So far, 👑ZVX Pro👑≥ZST Pro X>Eldar≥OG QKZ VK4>Duonic Silver.

The sound was really flat and thin, with practically no bass, when I played directly from my phone—an S26 Ultra. I was actually really disappointed. But once I installed the Enhanced Equalizer app, they turned into something amazing—truly impressive. This definitely isn't an ad for that specific app, but I do recommend using some kind of equalizer booster. The fitment was perfect for my ears with the included tips, Comes with two tips. The drivers might be a bit too big for small ears. In any case, the price is very low, so it’s not a huge loss if they don’t fit. So a Huge Bang for Small Money

These earphones have a V-shaped sound profile with significant emphasis on the low frequencies. The low range focuses more on scale and depth than on impact, and it moves in a somewhat agile manner without being dull, so it doesn't feel frustrating. There is some bass bleeding and it's a bit opaque, but the vocals are still fairly listenable. The sound is clear and the vocals are distinct. In the case of high frequencies, the timbre of the BA does not feel too harsh and doesn't give off a cheap impression. However, these days, the earphones have a very noticeable balance issue, which is a downside. The resolution, separation, and soundstage are also somewhat disappointing. For those who value low-end expression and have a certain degree of tolerance for Civil Balance, you will likely be satisfied. On the other hand, if you dislike the low frequencies being too dominant, please consider it further.
