LETSHUOER - S12 Wired IEM

My first experience with a planar driver IEM and the experience is excellent ! Once you start hearing from them, you will realise what all the hype is all about and you immediately notice the difference in sound quality. Only drawback in my opinion so far is slight discomfort. Have changed the stock cable and tips. Will see if it helps.

i was using rha ma650 from last 3 years. this is upgrade from it. s12 is great sounding. it doesn't distort at high volume like my rha. one complain though, its only have 1 year warranty whereas rha had 3 years warranty in less thn half of this iem's price.
Build quality is great. cable is also high quality & tangle free. and all tips are easy for my ear. 2/3 hours wearing won't give you any kind of fatigue or pain.

First of all Thanks Concept Kart for the quick delivery, I just got them the very next day.
The below review is my opinion on the S12. I'm new to the audiophile hobby..
If you're a bass-head but also love treble at times, this is the way to go.
This IEM paired with Lotoo paw s1 and topping NX7 is just the best combination out there.

The body is CNC aluminium, so build-wise it's excellent. As to the sound, first thing you'd notice is how crisp and detailed they are! Deep but tight bass, with heaps of sub-bass presence. Slight recession in mid-range, but absolutely no muddiness is noticeable. Layering is also excellent, especially in multi-instrument tracks. 'Playing God' by Polyphia is a good example. Percussions hit hard, but being planars, don't slam like dynamics do. The well extended treble results in a quite airy and detailed sound signature, making it excellent for EDM tracks. Although I would like to point out this might make listening to it fatiguing to treble-shy listeners. It took a while for me to get used to it myself, coming from a much warmer T3 plus.

But, to remedy this, you can EQ these to suit your taste, and unlike DDs, these take EQuing extremely well. You can convert these to absolute Bass or Treble monsters (or a mixture of both) and these will sound fine. No intrusion on the midrange, so no accidental muddiness to voices, while still sounding organic and life-like.

I did however face some fit issues. At first I tried the Moondrop springtips givent to us free-of-charge by CK. These didn't work as they have a shallow fit and resulted in irritated ears, same also with the one's that came in the box. Finally using Spinfit CP145s removed all of the issues, while ensuring deeper fit.

5 Star for conceptkart for making it possible for Indian audiophiles to buy niche iems like these.

The iems sound great. Fantastic bass, mids that sound natural with tons of detail and treble that albeit on a bright side, is not harsh with plenty of detail.

The 3 star unfortunately is due the slight channel imbalance with my unit. It's 0.3-0.4dB louder on the left side. :(
