YinyooKZ ZST Colorful Hybrid Balance Armature with Dynamic In-ear Earphone 1BA+1DD Hifi Headset (Purple, No mic)

These IEM's sound very clear and are impressive value for the quality. They come with 6 pairs of tips (3 White and 3 Black sets, 3 sizes).I use these on my iPod and my PC for video, music and gaming purposes.One thing to note on the PC side of things is that i occasionally had issues with low humming sounds while playing a select number of games. It's been a couple months since i last noticed this (may be one of those random things)This seemed to be down to the electrical noise created in my system while my Graphics card was under load. Switching to front panel audio or using a cheap USB sound card resolved this though i did have to sacrifice a little audio quality.Im yet to test the results with a proper PCI-E sound card but im sure there will be an improvement.

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 ISOLATIONFit 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 GenresRunning 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.

Decent sound quality for price and they look super cool. Pretty huge though, I thought they would be similar size to my KZ ZS10 Pro X but they're quite a bit bigger. Still fit fine though

Great little pair of headphones, surprisingly clear, balanced, and expressive with full deep bass that isn't loose or muddy and free of any high volume rumbles or rattles, very linear and expressive mid range, with extended but not artificially accentuated high frequency extension (like many low quality headphones that extend bass and high end to make up for their shortcomings). Highe end frequency reproduction was natural, and poignant without any harshness. They are lightweight, look and sound great for music and calls, fit very well and stay in place. All for 17 pounds. I've paid a lot more and gotten a lot less. The only thing to be aware of is they do require about 24-48 hours of continuous playback in order to "burn in" and smoothen out a bit as the drivers need to loosen up a bit or they sound strident,or screechy when first used. I think any negative reviews must have been people that didn't really give them a chance to settle in.

I bought them as a gamble and what a terrible gamble it was! Sound was clear, however whilst playing drums I lost most of the band apart from the click and singer. Will not recommend to any musician.

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

Never left an Amazon review ever, but recently I got tired of my AirPods Pro 2 being dead and not telling me so I grabbed some headphones for the gym. I bought a pair cheap USB C headphones and returned them as they sounded awful. I bought these instead, and my god. I’m not even kidding they sound better than my AirPods Pro and on par with my £800 mixing headphones. I work in audio mixing music so I’d like to think that my opinion matters for something! Definitely get these. Incredible for the money.

Good value for money
