Stunning IEMs

I like the S12's very much. The fit and the build is very good. The cable is excellent (no tangling and soft). And then the sound: it retrieves lots of details with ease. The highs are smooth and all is there, mids are very well presented (you hear minute details in music that you do not hear on other IEM's) and the bass is all there until the very low. It is not a basshead IEM nor a pure analytical IEM. The IEM seems to have no trouble in generating all details and nuances in complex music. Like is is very capable. For this price i thin it is the best IEM around, and i definitely recommend it. If you buy one, you will not regret it for sure. I use mine with a 4.4 balanced cable on multiple devices ranging from IFI dac/amps to high end DAP's. It never disappoints.

Letshuoer S12

Order was quickly fulfilled, package arrived fast and save.
Great comfort, light and sturdy.
I use them balanced, with a Qudelix 5k andan Ibasso DX 31(300 + Amp 12).
With silicone tips it is has a bit too much treble for my liking. But with foam tips, they are great. Great technicalities, very good tuning.
I just bought a Sundara and i think they are better or at least equal while much cheaper.
I recommend to give them a try.

🎧Absolute control and power over the sound.

My first planar headphones, it definitely has a different sound level and gives a much greater experience than you could ever get in headphones with a dynamic emitter, excellent tonal balance, a wide and three-dimensional scene and stereo panorama, excellent separation of instruments and drawing images.Maximum sound control, high-speed and attacking low frequencies with good depth and texture, sub bass is audible even on low notes.
The middle frequencies have a rich and wide sound, especially in vocal compositions.
High frequencies have excellent detail, wide resolution and nuance elaboration, do not have resonances and sibilants, these are the headphones that you can listen to literally for hours, I definitely recommend it!

Delivery is quite fast and it took about a week plus to deliver to my place. Sound is very fantastic and very engaging. I prefer to use it with a dac dongle so it will reveal more details. The S12 is very light and comfortable to wear. Stock cable is pretty thick and it looks expensive to me. Highly recommended!
