Proper EQ ing is a joy

So I received these as a Christmas present, fortunately I’ve read and watched as many reviews as possible. So I knew what I was getting and I had no delusions. Straight out of the box they don’t possess the signature I prefer. Secondly they are a monitor not a standard earphone. So I simply lowered the midrange by 5 db and increased the the 16 thousand cycles eq to plus 10 db . Now I have a pair of fully functional great sounding monitors. I only have one complaint I have small ears and these bad boys are large just a hair big for my comfort. Overall the sound is detailed and pure . If you never heard monitors then these are not for you. But if you appreciate great sound with a minimum of tweaking . Don’t pass on these unless you have unnaturally small ears . Five stars . I own a number of earphones and headphones mostly with V signature like Hifiman Sundara’s . These stack up to those others when tuned correctly.

Not quite what I expected

The out of the box experience with these is not great: the bass is overemphasized, and the mids and treble are overly attenuated. However, all is not lost as they respond very well to EQ.

If one is prepared to EQ them then they sound great. If not, there are better options for the money.

Fantastic HiFi in-ear headphones

These headphones are legitimately the best I've used so far. The balanced armature drivers have absolutely NO buzz, rattle, or distortion of any kind at low or high volume. The high-end sound is bright and clear but not harsh, the low end is surprisingly deep and sibilant but doesn't blowout or muffle any other sound. These will faithfully recreate classical music just as well as bass heavy rap. I would recommend these for music, movies or games. They work especially well with 24-bit hifi audio, and binural audio such as Dolby Atmos. You will need a fairly powerful quality DAC to drive the bass armetures to thier full potential however.

The fit is perfect. The shape of the headphones fits like a glove in the lobe of your ear and prevents fatigue from extended listening. The stem is compact to avoid irritation in the ear canal, while the flexible tips create a good seal and a moderate amount of natural noise isolation. The curved semi-flexible cable snugly and securely fits around the back of your ear and won't come out on their own. They are easy to clean as well.

They look really good too with a black body and gold accents. The colors and compliment your wardrobe when wearing them in public.

The good attempt

Specific IEM's

Let me start with the one positive, I only enjoyed this on one genre so to speak(Instruments), and on higher resolution tracks, Orchestra such as Mozart "The Requiem in D Minor" and Takeshi Inomata & Ichiroh Masuda - "The Dialogue with Vibraphone". If that genre is all you listen to, then these might do it for you, as they do pick up the little nuances and sounds on that genre of music really well, with nice imaging and the bass adds little hints of texture to it all when needed. So because of this one redeeming fact I won't snuff it out with a 2 star, and if that's all I ever listened to, then I would give them a 5 star, but it's only a small part of my listening, and so a 4 star will suffice. Also using a XDUOO TA-10 amp with them.
If you enjoy other genre of music, I would suggest their "ZAX" for edm/pop/MMD/Nightcore or their sister co., "CA16" for Rock.
But this is just my opinion and what my ears like so keep that in mind.
