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 !!

Excellent sound quality and nice build quality

My rating is solely based on audio quality, build quality of earphone and the value for money. It does not factor in the packaging (read the full review to know more about packaging).
The build quality is good. The wire is kind of rubberised, tangle free and easy to use/store. The earbuds are quite comfortable too.
Sound quality is good enough, just not to justify the price.
I prefer earbuds over in-ear ones. I already have the VE Monk Plus. Compared to the Monks, these don't sound as good. Don't get me wrong, these earbuds are quite good. But the Monks sound so much better. The sound clarity, volume levels, etc are much better in the Monks. You can also get the Monk Plus cheaper (for at least Rs.200 lesser) and you have the option of getting a microphone too with the Monks. So, it just doesn't make sense to get these CatEar Mimi, unless you can't find the Monks anywhere.

The package I received was heavily crushed. The tin box was within 3 cardboard boxes with some plastic padding too. Despite that it was so heavily crushed that I had to cut & pry open the tin box with a knife. I assumed the earphones would have been damaged too. But thankfully they weren't.

If you looking for earbuds with a budget of 1000rs, go for this... There are many available, but this one lasts long, and looks are beautiful...it's mids focused, with good sound stage, good for watching films also

It definitely makes me happy how far we have come across over the years, especially in terms of earphones/earbuds. I remember buying the Soundmagic ES18 or the PL21 for 600 INR back in 2013, which were the benchmarks for budget earphones at that time. They had good sound quality (by 2013 standards) but pretty crap build quality.

Fast forward 2020 and we get the Cat Ear Audio Mimi. My current load-outs include the BLON BL03 and the Fiio FH1S - which are both in-ears. So, when I came to know about the Mimi, I was definitely fascinated by the build quality, overall packaging, large driver size and of course the glowing reviews. I'm not an earbuds fan because of their low isolation, but Mimi changed it.

The packaging is nifty for something that costs so cheap. The earphones come in an all aluminium circular box and the presentation is the best I've seen to-date at this pricing. And there's the build quality - it's just brilliant. The wire is almost tangle-free (a little on the heavier side) and has immense strength. The quality of the wire is quite similar to my 6K costing Fiio FH1S (better than the BLON BL03) - in terms of overall tensile strength and durability.

Lastly, the sound quality - the best I would describe it as a mid-centric earbud, with clean treble and just the sufficient amount of bass. I'm not a bass-lover, as I love my earphones to be neutrally tuned.

I have only tested Trance tracks (pre-2011) with these earphones and they sound fantastic, especially the vocal tracks. This has now replaced my BLONs as my go-to pair for everyday listening.

Safe to say, I'll be buying another one in the coming days because I want to keep a spare for this hidden gem!
