Yinyoo KZ ZST Wired Earphones with Microphone Hybrid Banlance Armature with Dynamic HiFi in Ear Monitors 1BA+1DD HiFi Headset Noise Isolation Headphones for Musician, Gamers (ZST Black with mic)

Very Good... in sound clarity.. lows and highs and bass all could be heard separately and distinctly. only draw back in no controller in the wire to skip to next or previous song or fast forward or backward. Had these button been there it would have been a complete package.

Great build quality, awesome sound, mind blowing comfort.. You will not regret purchasing this.. And thank you seller for the gift..

The Yinyoo KZ ZST Wired Earphones are excellent for their price. The sound quality is impressive, with clear highs and deep bass, making them great for music and calls. They are comfortable to wear for long periods and durable, offering great value for money. Highly recommend these earphones if you're looking for quality on a budget.

Excellent iem, the bass is exceptional and while the treble could use some improvement, considering the price, this product is a remarkable option.

Performance good. Balanced although bass is low. Reliability is one another thing. Connectors are delicate and flimsy

For the price this is the best sound quality, the fit is not best, but if you are in for pure sound and nothing else, this is a great buy

Treble is high, cause ear pain if listening for more than 2 minutes.

Worth every penny and sounds better than my airpods

I actually bought these KZ ZSTs (with mic) to serve as my new reference earbud after a recommendation from audiocheck.net as these are very inexpensive but provide some of the widest sound I've heard from an in-ear bud. But more on that later. I've been "into audio" since I was a teenager working on sound desks in a variety of situations and think I have a reasonable ear and wide range in musical tastes. But am aware that with advancing years, my frequency range of hearing and perception can change. I've aimed to measure things as objectively as possible within the constraints that my ears will not be the same as yours but refer to websites that you can check for yourself. Frequency response. Using the test files from audiocheck.net, I tested the low frequency response and I can hear down to 20Hz without difficulty. Using the 22kHz to 8kHz sweep, my ears kick in at 15-16kHz and the sweep progresses down to 8kHz without any painful peaks. For dynamic range, I tested them to be audible down to -60dB below full scale (volume set to 80% in Windows 11). The bass shaker track failed to identify any rattling which is also a good thing. FIT and ISOLATION Fit in my big ear canals was OK with the middle sized tips but I benefitted from using the larger size to improve isolation and any typing noise disappears when playing anything through them above very low levels. They are low profile enough that I might even give them a try as my buds for sleeping but have some more buds to try which are very low profile and claim to be better for sleeping. MUSIC Genres Running through my usual test playlist I've yet to find something I wasn't happy with. These cope with EDM, Jazz, Funk, Blues, classical/orchestral and I'm very happy with the purchase. Listening to the orchestral themes from "How to Train Your Dragon" was rousing and the separation of the instruments was impressive. Normally with in-ear buds the orchestra can sound like they are all bunched together but not here. Tl,DR; Thanks to audiocheck.net for the recommendation. With the 5% voucher these were only £19 and worth every penny. These are very competent earbuds which are very musical for most genres. My usual wireless in-ears are five times the cost of these and these will now be my reference pair against which other headphones are compared.

Not great cos they broke after using for the first time, they didn’t fit my ears and the sound quality was average but quite tinny, not the best for people who like to hear sound on good quality
