KZ - ZST

I’ve been using the KZ ZST X for over 3 years now, and I’m genuinely impressed with how well they’ve held up. Sound-wise, they have a V-shaped profile punchy bass, clear highs, and slightly recessed mids. Great for genres like EDM, pop, hip-hop, and casual listening. The detail and separation are surprisingly good for the price.

Comfort is excellent, I can wear them for hours without any fatigue. Build quality is solid for something in this price range. The housing is plastic but durable, and the detachable cable makes it easy to replace or upgrade to balanced cable, if needed. Noise isolation is decent too, especially with the right ear tips.

Even after all this time, they still sound clean and lively. For anyone looking for great budget IEMs that are reliable and fun to listen to, the ZST X is an easy recommendation.

I bought my first one in Sept 2021. It broke as i stepped on it by mistake and that also lasted for more than year..
Bought the same one again in May 2023 and still using it. I use it for office calls, watching movies and use it almost 10 hrs daily. Sound quality is one of the best in this price range..
Mic is okay okay but much better than cheap ones..

Bought them for the color back in 2021 :)
For the audio quality I would give it 3 stars paired with a ampdac 4, what made this review a 5 star is-

1. These are made out of plastic but it did not give out on me, handled the iems very roughly during this period without a care in the world and they are still being used in my gym sessions and will be continuously used rigorously.

2. Comfortable for long duration wearing as these are really lightweight.

3. The cables I thought wouldn't last but they are still working, they do have a small nick after 4+ years of usage but I put electrical tape on them (not deplorable at all XD)
They have become a little bit yellowish/darker I must say (Which happens)

all in all, they can last you long if you do happen to notice small things wrong with them and keep maintaining them.

also they get better with time as you listen to them play or maybe you start appreciating the range of the sounds they make (who knows)

I've had this IEMs since the beginning of 2023. This being my first audiophile set, I used it very carefully. And it took care of me too. This IEMs should be your first priority in this range. I love it. I'm sure most of you will love it too.

Sound is good and I used it for almost 4 years and they are still working

Bought two years ago but sadly the right side has stopped working now. Anyways still the best earphones at this price. Great sound and comfortable. Was wondering if i can order just the cable as the earphone are still working.

This pair of IEMs is literally the best purchase I've ever made. You can see a significant difference between normal earphones and IEMs at the same price range and once you use these, there's no going back.
