Cons -
- Very Fatiguing (can’t listen to It for more than 30 minutes at a time). I’ve only seen this issue on smaller ear canals though so if yours isn’t, it might work better
- Bass sounds a bit artificial
- High frequencies are elevated. For me, this adds to the fatigue.
Pros
- good Detail for its price
- vocals sound clean and slight V shape
- cable is good
- metal shell so might last longer than plastic iems
Conclusion -
It’s a good iem, if it matches your taste and fits you. But it’s hard to recommend to be your one and only iem.

Great iems for competitive fps gaming.
So kefine klean have one of the best soundstage and imaging in 12k price range. They provide detailed sound and has decent bass. These are my go to for cs,valo and other BR competitive games. I am not a fan of the sound signature cause I like listening to music on v shaped fun , energetic and bassy iems but the klean serves a purpose for me and I am happy with them.

Kefine Klean - Quick Review
Grabbed these recently, solid budget iem tbh. metal build feels nice, comfy fit, easy to drive from phone.
pros: balanced sound signature, comes with interchangeable nozzles (silver=warm, black=bright). quality exceeds expectations for the price.
cons: vocals can get sharp and shouty, pretty average bass performance. stock tips kinda suck, cable is just okay.
tldr: decent all-rounder but has some vocal harshness issues. bass nothing special. recommend if you can look past those flaws.

Pretty Good
Vocals are really clear. It lacks a bit of bass but that is expected from IEMs which are supposed to be accurate to the sound. Sound stage is also really good for a single driver IEM. The stock eartips are slightly uncomfortable.

I can't go back to my old headphones now, these have changed the game for me. Slightly uncomfortable at first as these were my first iem's, but I've been getting more used to them.

Probably the best IEM you can get for 2500
Build quality is top notch. It's heavy but not uncomfortable. Coming to sound it has balanced sound signature with slight emphasis on treble.

Best for the budget (~929 rs)
I was using Sennheisers CX80s with Samsung Galaxy A52s and it has 3.5 mm jack but the sound quality & output levels are very bad. So, I had to get a DAC and I watched a lot of reviews before making this purchase and one thing I can say is the sound quality is better than Apple's dongle becoz it only supports 16/44.1-48KHz .
The cable is super flexible and supports both Type C & Type A connection for PCs.

Summary review of the Mega5Est
These IEMs have a unique personality and it does match the many YT reviews that I watched before making this purchase.
The tuning is very neutral leaning slightly bright. These IEMs will present all instruments and everything that is present in the mix without emphasizing. Bass and sub bass present without any mud or overpowering of other frequencies. Mids are well presented, in fact these are all about the mids which are mostly neglected in favour of bass tightness and extended treble.
I found the vocals slightly forward but not harsh, in fact nothing is overpowering in the presentation here which may come across as boring but it is simply presenting the songs as is. You can easily drift off mentally while listening, the presentation is so neutral and focus back whenever you wish to.
Overall these are very solid IEMs good for analysing and casual listening both. Tuning preferences may be highly personal and there may obviously be many who may not prefer this kind of tuning but still this doesn't take any points away.
I am happy with the purchase and prompt delivery.

This IEMs delivers excellent sound across all music genres and is used daily. The unboxing experience is premium. However, a minor issue has been identified: the right-side IEM produces a subtle noise when tapped while worn, which may indicate a manufacturing defect.
