KZ ZST Dynamic Hybrid Dual Driver in Ear Earphones (Black with Mic)

So the quick advice here is...just buy them. For the price, nothing else can touch it. At some point I plan on putting up a thorough review, probably with video, but for now it's very simple: if you want high-quality in-ear monitors for a low price, just go with these. Lots of bass (maybe a little too much for some folks), but with a clarity all through the mid- and high-range, and a nice, crisp high end. They are not to be confused with other earbuds in this price range; these Chi-fi ear monitors should be compared to audiophile and/or pro gear in the $100-$500 range on the basis of comfort and sound quality.I've had them for a while now, and basically have nothing bad to say...if I'd paid $300 for them, I'd have a few nit-picky things to post, like the rather cheap-feeling mic housing with the pause/play button, and the flimsy-feeling cables (but it all works and has held up so far). But at this price point, there are simply zero complaints--if it breaks or gets lost I will immediately buy another. Heck, I may order some more just to have backups or an extra to always keep in my backpack.I have worn them for several workouts, both running and weight lifting, and they remain in place and comfortable. Do make sure that you seat the cable connection completely; I noticed another reviewer said his cables always fall out, but you just have to seat them VERY firmly and get the tactile "snap" to let you know that the cables are all the way in place. On one side, it felt like I was going to break it I had to push so hard to plug in the cable, but I finally go the "click" and I have not had a single issue with the cables becoming detached.I had my brother do an A-B comparison with them and some pro in-ear monitors (he is full-time Tech Arts with a church of over 30,000 members, and has access to "the good stuff") and he says they compare favorably with Shure 425 and 525 ear monitors. In his words "the bass is a little boomier, and the highs are a little crisper, but the clarity is there" in the KZ-ZST. And then he immediately ordered some of his own, because he couldn't go back to his Sony earbuds knowing that the ZSTs only cost $20. And that should tell you all you need to know.Either watch for Amazon to get some back in stock here stateside, or go ahead and order them and wait a couple weeks or so for them to come in from China...you won't be disappointed for the price. If you doubt me, go read the Wired article on KZ that focuses on the ATE model, then extrapolate what another $7 gets you: dual drivers (balanced armature-style), a mic, a control button, and removable/replaceable cables. Can't touch these for the price, buy them before they get expensive and even harder to get from China...KZ is busting the earphone racket, might as well get on board.

These are the best $20 set of in-ear earphones I've ever used. They sound as good as or better than other in-ear phones that have cost me up to $100. They're also as comfortable as any others I have tried when used with foam tips.As with any in-ear earphones, you need to be sure to get a good fit that provides a complete seal in order to hear what they are capable of sounding like. Without a good seal any in-ear set of phones will sound tinny with absolutely no low end. Since everyone's ear canals can have different shapes, what works for one person may not work for another. Keep trying until you find tips that fit your ears comfortably while providing a good seal and then you can use them with a wide variety of in-ear phones.I have very large ear canals and the silicon tips that were supplied with the ZST in-ear phones are all too small for me to get a good fit. The largest pair of tips are almost but not quite large enough.I use the "RIYO Premium Memory Foam Earphone Earbuds Tips Noise Reducing Earbud Tips for 5mm-7mm in-Ear Headphones Nozzle" sold here on amazon by seller yannl. They work just as well for me as the much more expensive Large Comply Foam Tips do. I stocked up on Comply Tips way back around 2008 or so. When I finally ran out a few years ago the sticker shock from what they now cost led me to find an alternative!Though each design has its own distinct characteristics, these compare favorably to the following earphones I've also used extensively over the years:Shure E2c (long since replaced in the Shure catalog by SE215) with Large Comply Foam TipsKlipsch IMAGE S4 (both original S4 and S4i Rugged) with both the Klipsch oval shaped large silicon tips and Comply Foam TipsAKG Q350 with the largest supplied silicon tipsV-Moda Vibe with Comply Foam TipsSkullCandy Ink'd (original) both with the largest supplied silicon tips and foam tipsJVC HA-FX33 (original "Marshmallow") with supplied foam and "Kramer Mod" with cotton instead of foamAuvio 33-286 In-Ear Armature with Comply Foam TipsKoss "The Plug" with supplied foamKoss KEB/24 with supplied foam as well as with foam from JVC Marshmallows

There is a faint buzzing noise that you can hear when the volume is really low. you can’t hear it when you’re listening to music or playing games at a normal volume.I like how the cord clicks into the buds, it fits nicely into my ear too. Great price to performance value I don’t anything else could beat it.Pretty easy to use, just plug and play with computer or gaming console.Audio clarity is an 7/10 because of the faint electrical buzzing noise at low volume but with normal use there is no issue.
