Hi guys, today I am reviewing the KZ ZS1 earphones.
Enjoy the written review below, or check out the video review at the end of this post!
I got this pair for free from the KZ Global Store on AliExpress. Check them out at the link below:
Now let's get started.
Overview and Design
I got this pair as a free gift from the KZ Global Store on AliExpress. Paying customers can find them for around $8 on AliExpress and a number of other sites as well.
The ZS1 has a unique design; it's made of hard plastic and feels like a premium earphone. The design ensures that it fits extremely snugly in your ears, but more on that later.
The ZS1 does not have detachable cables, as this is an older model, KZ didn't really have earphones with detachable cables at the time of the ZS1's release. The cable is the usual KZ rubber cable. KZ has made a great new braided cable though, which is included with its newer models.
The ZS1 is an absolute bass monster. Bass is on the level of the ES3 and ZS3. However, the overall sound is quite disappointing. It sounds muddy and muffled, in general. Highs are clear but not sharp or crisp -- same goes for the vocals, although the vocals are audible, they just aren't that sharp.
The sound may be a bit disappointing, but as for the soundstage, however... you will not be disappointed. The ZS1 is a very wide sounding earphone. Instruments are separated and music sounds like it's coming from around you. The overall soundstage is dark sounding.
The ZS1 is a great performer when it comes to blues or rock music. I listened to some Albert King with these earphones and I was blown away by how wide and spacious the song sounded. Rock music also sounds good, but again, not very detailed at all.
Bassheads will want to consider the ZS1. It provides adequate bass, quite deep even, and rap/trap music sounds decent, at least when it comes to bass. Vocals and other instruments just sound kinda dull and muffled.
The ZS1 is one comfy earphone, though. The seal is absolutely amazing. They just fit right in your ears, even with the stock ear tips. They just fit naturally in your ears and don't fall out.
Since the ZS1 has a great seal, it means they also isolate noise quite well, on par with the ES3, even. You will not hear outside noise, and as long as you have a moderate listening volume, others won't hear your music either.
The ZS1 has a good design and it feels like a premium earphone, well above its $8 price tag. The sound quality is rather disappointing, especially since KZ has a history of releasing great sounding IEMs for a budget price. But it's not a bad sounding earphone, especially since the soundstage is very wide and bass sounds deep and good. I like the sound overall but let's just say I have better sounding earphones than the ZS1.
Comfort is good, they have a great seal and noise isolation is exceptional. So overall, I think I'd rate the ZS1 a 7/10 -- the weak, muffled sound is compensated by the very wide soundstage and booming bass. Happy listening!
