The Good:
First time you put this on you would notice is the soundstage, its width, but lacks in depth perception. It has a mid – focused tuning. Vocals has got a significant life especially male vocals but it needs slight refinement in higher female vocal notes. Based on mastering and your source the mids could sound quite intimate, depending on your taste it could sound shouty. Significant amount of sub-bass roll -off which is expected out of most earbuds is present here also. However, this doesn’t mean it is not enjoyable you will definitely feel the kick drums and other percussion instruments but you would wish it had slightly more bass, but that's quite user specific and depended on genres of music you listen to. Bass heads- it's better you look for something else. This wouldn't satisfy your needs. Quantity of the bass present doesn’t bleed into mids. Drivers are quite sensitive and of impedance of 32ohms hence you can drive them of your phones. I have to admit the cable is quite amazing for it's price.

Bad:

The donut ear pads provided needs to be slightly larger. First time users will just tear them right apart on putting them on. For me I got better bass and mids response with full foam pads which was not provided in the box.

Instrument separation is not top notch, picking out instruments can be a little difficult but these are $10, considering the price to performance ratio it's a bang for buck in terms of imaging and instrument separation. Treble is where it where it lacks again. Those cymbal strikes, hi-hats and decays sound veiled. Wish it had slightly more sparkle to it.

And The Ugly:
I couldn’t find any.

Verdict:
That initial wow- factor is created due to the lush mid-range and soundstage.
Overall, I would rate it 3.5/5.

These earphones look beautiful. The cable has a premium built, quite heavy, and does induce stethoscopic noises but I am okay with it.

I drove the earphone from my Schiit Stack, XD-05 and iBasso DX160; in daisy chain and found great results. The sound signature is slightly warm, the treble is airy and much better reciprocated than the VE Monk Plus. The mids are not recessed and sound as they should. The bass is not as punchy and dynamic as the VE Monk but the remaining spectrum more than makes up for it.

It is a pleasing earphone, destroys any competition till 2K mark. My Hifiman Re400 was sweating at the 2K mark but they offer much better comfort and isolation. Tonally, I have no complaints. Technically, there isn't much room for expectations but I could identify 3-5 points where imaging is prominent in the limited soundstage. Which again, is much better than the VE Monk. Overall, this is a well-rounded earphone and edges out the VE Monk in my opinion.

I commend The Audio Store for retailing such earphones, that is not as brutally marketed as some brands (ahem bOat) - but do their job gracefully. Another addition to my collection.

I ordered these and was pleasantly surprised. When compared to RY4S(I have 32-ohm model) and Monks Plus(from memory):

Mimi is somewhat better in the mid-range than both. Treble has some sort of magic. However, the sub-bass is inferior to RY4S and better than Monks Plus. I think the quantity of bass is okay if you add some through EQ.

When compared to IEMs, When you listen to any stringed instrument on this, it will be hard to enjoy it on any IEMs. Same with vocals. They sound way too natural and coherent.

Downsides:
Frequency extension is bad. Even very cheap earphones that are bundled with phones are better in low end.

The soundstage is wide and open BUT it makes my ears pain due to weirdly positioned bass. Especially if tracks have a drum or something not at the center.

Highs have a peak somewhere. maybe somewhere between 6k to 8k and it pierces your ear at times.

Overall: quite possibly better than most earbuds at this price or near to them at least. My use case is to listen to acoustic tracks, stringed instruments, etc. For everything else, IEMs are better.

So the Monks (+) have finally met their match ! Superb first effort by CET, giving you a lush, analogous sound across all frequencies. Build quality is well above its price point, specially the wires. Tested without amp on an LG G5 (using Dub Music Player) and the sound was amazing - warm and very detailed, across genres. A keeper !!
