After a lot of research i bought these, initially the y didn't sound that great but please keep some patience and do a minimum 50hrs burn in, they shine like a diamond, dont compare them with expensive Iems, they are a decent pocket friendly iems, only drawback is their flimsy cable and cheap bud tip i would suggest to get a memory foam bud tip

Sound quality is fine. It's good for most. Bass is excellently accurate and well placed. Male vocals are little bit weird I don't know. Treble is good.

Silver cable is included. It's aesthetically little too exposed😂
Fit is good.
The earphone is overall good for the price.
Vocals probably need improvement

I was using the KZ ZST before and then switched to KZ ZSX, and this is my second purchase for my girlfriend. Very open signature of sound, soundstage is quite well defined and the bass is accurate, not jarring while mids and highs flow in pretty well. Its great for audiophiles in a budget.

Been using for almost a month or so I found it quiet promising to handle almost all genre's of musics, especially the highs are very lively.The mids are dealt with 3 BA's and u can feel the effect in the soundstage and especially the seperation which is as good as black and white and not grey or so. It's a warp design and thus u feel being at the midle of stage.The bass is super smooth and lively accompanied by the sub bass which is really clean...The music details and instruments are clear and mesmerizingly glowy. It's a Terminator....terminate is what it does to other IEM's😂.At this price, it's a great choice and I had scoured all internet and for month to buy it so u can save the chase... it's pretty awesome...The seller is a nice guy and a humble helpful fellow.So he will assist u very nicely even after u completed the purchase too.just one thing to seller that u can provide a carry case to everyone if possible, if u feel generous 🤣lol.

Great sound amazed by clarity and volume of sound it can produce really go for it
