Right now I would like to apologize to the folks here, for the review or thoughts that I am going to share based on what I am hearing from the Zeroes is that, I would be all over the place and not in a formal format, for I got sick this week and I have been recovering, getting better day-by-day but I feel much better compared to the previous days when my sickness was at its maxium effect. Also I admit I won’t be able to showcase tracks that shows the strengths or even the weaknesses of the Zeroes, for I have this tendency of my brain just shutting down, and just go autopilot, every time I play tracks that I love listening to therefore I cannot tell you guys much technicalities like some of the experts here.
Ok so to give you my thoughts, the title says it all, how the hell is this 20USD?! Like 7Hz, what kind of black magic fuckery did you do to make a 20 dollar IEM like this sound very clear and clean, hell it even rivals the Moondrop Starfield I have which is a 110 Dollar IEMs back then! Sure it is negative, I was expecting that the sounds of these are going to be like at least the Final Audio E1000 in terms of sounds, meaning there is good tonality but meh resolution but no, this has better resolution! and it is almost the same as the Starfields, sure it’s not going to be Kato levels of resolution but my god for 20 freaking dollars, that is impressive and a tale that the IEM game for years to come is only to get more impressive more than ever. The soundstage on these is pretty freaking good, for I thought it was going to be one of those IEMs where I can consider average soundstage due to its given price but damn, it’s very good and wide, not as good as my Seek Real Airships, but there is soundstage in these that I can have no problems living with. The sound signature is one of my favorites, for I am a neutral/balanced head and these have it according to the graphs I saw from HBB, crin and other well known respective hifi reviewers. I knew from the get go this is not going to be a bassy IEM, but I am fine with for I prefer a bass that is just the right amount, not too little, not too much just the right amount of bass for my bass. Mids are freaking detailed from these and as I said I am expecting an average overall sound, but not this fucking proved me wrong and was able to enjoy my library the whole day especially on tracks that emphasizes mids more and the Zeroes do a freaking good job. The highs, just the right amount for me and it’s not one of your treble murderers for your ears, the high-end spark I hear from these especially to acoustic tracks, man again, how is this 20 freaking dollars?!
Ok so quick things, the stock tips? I have been using the one that is out of the box and I have no problems with it, probably it’s because I don’t have any tips left that I can use for it, I mean if you want a bit of bass and tame the treble a bit, the E-Types do that. The cable is fine, I mean it’s not going to be a very high-quality cable like the Xinhs cables that I have but it’s good enough to be used, also it’s detachable unlike the Chus. The build is plastic, I mean it’s 20USD but I don’t mind it since I cannot complain about it for its given price, I mean if I was given a choice like a metal build but attached cable or a plastic build with detachable cable? I would go for the 2nd choice. Also despite the looks and me being skeptical of the fit, it is surprisingly ergonomic meaning it just fits me right.
Some cons, let’s see the bass is not that typical punchy bass to those who are into bass, there is bass but it’s not going to be your bass that is in your face, therefore bass heads not for you. The treble can get a bit too much to some even though in my case it’s not like that, so be sure to have ear tips that tames those highs a bit to those who are sensitive to treble. Speaking about the highs according to major hifi, there is going to be peaks from the treble that is going affect and cut through the timbre at times, a bit of a let down, and I can say it’s true but most of the time I can tolerate it since you know 20USD. Let’s see the plastic build as I said, might not be your cup of tea for I know there are some prefer an overall metal build just like the Chus, but for me I am fine with it for the plastic build seems solid enough for it to last long.
So yeah overall, I think THIS is a must have to those who are in a budget, new to the hobby or even freaking veterans! Everyone should at least have tried the Zeroes, I mean for me, I bought this for just 15 bucks just 5 dollars cheaper and it is the best 15 dollar purchased I have made this year! And yes! I prefer these over the Chu and the Aria, especially the Aria for the Aria is just too boring for me nowadays.
Pretty much my thoughts exactly as I said in my review. Prefer these over the Starfields/Aria and Chu for sure. 
Aside from the EJ07, I hope 7hertz will release an upgraded Zero with more drivers and bass, and tamer uppermids.
