Great sound quality, end-game IEM at about $100
This review is for Letshuoer S12 in-Ear Headphones 14.8mm Planar Magnetic Driver Wired in-Ear HiFi Earphones for Smartphones/PC/Tablet (3.5mm Connector, Gun Metal Grey).This is my 5th set if IEM after the following:- 1More trip-driver.- Celest Rue.- CCZ DC-02.- Tanchjim Bunny.I also own Sennheiser HD6xx (open back) and HD598cs (closed back), as well as regular headsets including Apple AirPods 2, Apple AirPods Pro 2, Bose SoundSport wireless, Surface Noise-Cancelling headphones, Jabra Evolve2 65, and a few others. Now I believe this is the end-game from IEM perspective, just like HD 6xx for over-the-ear models.I am not an audiophile, and I am not interested in collecting earbuds/headphones, I just love music and would like to find the right tool for enjoying my music collection. When I am away from my desk, I need a pair of small earbuds which are easy to carry without sacrificing music quality. Believe or not, even though Apple AirPods 2 are very good (great noise cancellation, superb convenience using with iPhone), but the sound quality doesn’t cut it. Each cheap sets I got in the past are progressively better, among those the best one is the Bunny. The almost perfect Harmon tuning makes most of the music truely enjoyable. It’s very good in most of times, only in some serious classical music occasionally I would notice its shortcoming, particularly the low bass and clarity at the treble range. This led me to find a better one so I can forget the existence of the device itself, so the music can be truely immersive.Letshuoer S12 is exactly what I am looking from every perspective.In the box, besides IEM and cable it also carries a nice-looking hard-carry-box. It’s high quality and served as a good protection to the device when it’s not in use. 1 set of foam tips and 2 sets of silicone ear tips are provided, each set has 3 different sizes. I couldn’t tell the difference between 2 sets of silicone ones beside color, foam tips is for better sound isolation to achieve a better bass, I picked black silicone for its color and ease of cleaning. My ear canal is small, so I picked the small ones. The quality of the cable is excellent, the plugs at 3 ends are all made of metal, the twisted wire looks super sturdy, the earbuds are made of metal too. Everything looks super high quality.The sound quality is excellent. I feel across low bass to mid to treble the entire frequency range is well balanced, no extra emphasis in the bass, no tune down in the treble, it just delivers the original sound that I am supposed to, and I want to, hear. The clarity is unparalleled, and best of all it responds to large dynamic range really well. In “Also Sprach Zarathustra” by Herbert von Karajan the low humming part in the first minute, and first several minutes in William Tell Overtures by Carlo Maria Guilini, where my previous low-price IEMs struggle, S12 handles them so well and so naturally. Among several symphonies, operas, and pop song I tried so far, I haven’t had the feeling of “wow, this is impressive and so different”, but I do notice some small details that I didn’t hear in the past, and overall feeling is it’s immersive, natural, and the music is full of me and I don’t feel the IEM itself. It gets itself out of the way.In term of comfortableness, I can wear it for hours without feeling fatigue. The buds aren’t heavy, the silicones eartips are smooth, the design of the vent makes it possible to not build up any pressure in the ear canal.In term of sound isolation, it’s very good. Obviously, there is no way to compare with AirPods Pro 2, but I cannot hear what my kids are arguing about near me, my wife has to tap me because I wouldn’t notice otherwise.Given the superb construction quality, excellent design, and best-in-class sound quality, I think this is a no-brain buy for IEMs around $100. It’s so much better than any wireless earbuds at any price range in my opinion, assuming you don’t mind the wire. it’s simple to use and will last for years considering there no battery or anything to go bad. I strongly recommend this IEM to all music lovers!

This is one of those IEMs that will be referenced in a decade. It’s that kind of IEM.
Amazing value for the money. These boys eat several $300+ IEMs for lunch. Clear, bass extension and texture. If you’re super sensitive to higher frequencies you might find them a bit bright. Most large planar IEMs have this characteristic. If so their S08 model might be up your street. They’re both great and punch above their weight. Bars lol. Solid metal design, lightweight and not too big… It’s an easy rec. Form and function. Can’t really ask for more!

Unsubtle Excellence
I got these after experimenting with other chi-fi IEMs up to the very expensive Kiwi Ears Orchestra Lights and being pretty disappointed despite listening to lossless files through a decent DAC. Instead, my favorite so far were the $50 KZ ZS10 Pros. I guess I just don’t have very refined ears. These are the first planar drivers I’ve owned.I went looking for an upgrade to my ZS10s and was pointed to the S12 Pros. I was not disappointed. I paired them with some Spinfit W1 sleeves and they’re by far the most comfortable IEMs I’ve ever tried. No hotspots or strain. I wear them for hours with no discomfort whatsoever. The build quality is also excellent. Understated design but very solid feeling construction.The sub-bass is front and center, though it can get a little muddled when playing compressed files. The mids are well-balanced. The treble stands out spectacularly, though can get a little hissy with prominent sibilants. These IEMs need to be pushed to really bring out the soundstage, which may be unsuitable for listeners who prefer lower volumes. For me, the best sound is on the upper range of my comfort.For my taste, they create a wonderfully bombastic sound. Though be assured that these IEMs do not create a “refined” sound. They make no illusions about how sculpted the response is. However, if that’s what you’re after, look no further.

I canât have nice things. But maybe you can.
Excellent sound quality. Hard to find this level of depth and detail retrieval at this price. One issue though. These things will not stay in my ears. I donât typically have issues with earbud fit. Iâve tried all the included tips plus three others I purchased separately. Nothing will get these things to stay in. And if they do stay in for a short time, itâs because I pushed them in forcefully and they become very painful. Disappointed by this. I want to use these but I just canât. I know everyone is different. You may not have this problem. Thatâs why I only took off one star. An otherwise perfect iem is unfortunately useless to me.

Very high quality with the good stuff included!
These sound so amazingly flat and balanced! The quality feel to them speaks volumes so to say as well! Lol I just love these! The have intrigued me and have become my new daily use earphones. They have a very good wire they come with and I saw no need to upgrade it but I will change it our in the future days just to compare. I also put on foam eartips to compare and I lime the sound and fit much better. Bit with what is included for tips is pretty great too. I just prefer the comfort of foam. These feel like they’ll be with me for a very long time. Thank you so much for building such great things Letshuoer!Thank you for reading,Erin

They sound as good as everybody has said for years
Holy crap these sound good! The PLANAR sound in miniature. I’ve wanted a pair of these for two years. The balanced cable is short.. see pic.

El sonido del S12 es muy diferente a la mayorÃa de los audÃfonos, ya que usa un driver planar magnético, y se nota en la calidad de audio.

I purchased these to replace some problematic Jabra earbuds. These are half the price of what I paid for the Jabras and absolutely slaughter the Jabras on every metric. They stay in my ears unlike the Jabra Elite Active 75t’s, they sound fantastic and the sound doesn’t cut out like it frequently did on the Jabras. I have paired the S12 Pro’s with a Qudelix 5k and am using the 2.5mm balanced connection. Even with the included 3.5mm connection they are capable of LOUD volume without any distortion apparent. The Qudelix 5k app has an included Parametric EQ setting for the S12 Pro’s which further improves the already brilliant out of the box sound quality. Very impressed, I am hard pressed to choose between listening to these or my EQ’d Focal Elegia closed back headphones.
