LETSHUOER S12 in Ear Monitor, 14.8mm Planar Magnetic Driver HiFi IEM in Ear Earphones (Nebula Grey, 4.4mm)

I've had the whole lineup of Hifiman up to the Arya and these are my new daily drivers instead. Make sure you have an amplifier has 2 ohms of output impedance or less to match them properly and not affect the sound. They're easy to drive, in low gain on the 3.5mm jack on a Topping A90, so it's a breeze. Soundstage, details, you name it, these have tons. Cons: Soundstage is wider than depth (front to back) but not that much. Even playing in Destiny 2 it was a blast as you can hear a pin drop 30 yards away. If you want to max them out, get another amp I have is the Topping L30 II and an E50 DAC on optical and you'll have a noise floor so completely black you'll think you're haunted. They are really smooth and a little slippery if your hands are dry and clean. There's 3 sets of tips to pick from, so comfort is just trying a few, but I started with the black foam mid size and they're good. If you hear the mids sometimes sound "shouty" at certain notes, switch tips and make sure they're fitted because tips and fit are everything with these. Flac are a must, also the JDS Atom Amp+ DAC+ is amazing with these if you want to buy American. Someone just posted a song on a message board to ask help listening for artifacts, and I told him I could hear his chair rustling as he played keyboards which he wasn't aware of. These are REALLY detailed if you have a great source and flac files. If budget is the issue, get the Truthear Crinnacle Zero which is the only other IEM's I use. They need no equalizing, but they do need more current than a phone will have. If it outputs 2 volts at least you should be fine, just not less than that.These are great if you've ever had the Hifiman HE6SE and equalized them with a -6db preamp reduction, and realized you need an amplifier that can power a lighthouse to get them loud. I'm checking out of the rat race for crazy power after hearing these. Also if you wear glasses, seal problems are solved. If you have balanced, get the 4.4mm version, planars really make use of the extra voltage.

Vengo de tener unos HD660s y unos Dunu Titan S. Estos tienen una cantidad de detalle impresionante, los siento en este apartado a la par de los HD 660s, el sonido se siente lleno a diferencia de los Titan S. En frecuencias bajas es de lo mejor que he escuchado, ese nivel de detalle y representación de bajos no la alcanza ni los HD 660s. Los medios quedan un poco atrás por su respuesta de frecuencias en V, los vocales se disfrutan pero pierden un poco de protagonismo. En este apartado prefiero las voces en los HD 660s y los Titan S. Los agudos son muy buenos y muy detallados, aunque en ciertas canciones falta mayor separación, se pueden sentir algo conglomerados. No son para nada sibilantes, pero esto va a depender de cada canción. El soundstage es amplio, pero no hay muy afuera de tu cabeza, sin embargo la buenísima separación instrumental hace que el soundstage parezca más amplio de lo que es. Son unos auriculares impresionantes por el precio, son para disfrutar la música, para disfrutar de los bajos sin necesidad de perder detalle. Si te gusta un sonido más neutral quizá esta no sea la mejor opción, pero no defraudan para nada.

En pocas palabras son excelentes, para mi gusto personal, así es como me gusta escuchar la música, alejado y expandido, nada de que se sienta encerrado y muy cerca del oido.

These are probably the best all-round IEMs I've listened to (better all-round than all of my headphones, too).The tonal balance is, as the graph from most reviewers would suggest, v-shaped. The bass is more focused on mid-bass, and could use a touch more sub-bass, though the quality is great. Mids sound natural and detailed, though slightly recessed.The treble is both the best and the worst part. The upper treble can get a little spicy, making cymbal crashes, trumpets, and strings in the high frequencies come pretty far forward in the mix. That being said, the treble is incredibly quick and detailed, so it never sounds uncontrolled or sharp, it's just forward. Personally, I find it engaging; though some may find it too forward.Soundstage is average, though I have the Final A4000s so maybe I'm just spoiled. Imaging is above average, but not spectacular. Instrument separation, though, is great.One of my friends owns the Blessing 2: Dusks, so here are some comparisons: The Dusks have more of a sub-bass emphasis with more rumble, but the S12s have better resolution. The mids on the Dusks are more even and, in my opinion, are a step above the S12s. The treble detail is about the same, though the treble of the Dusks is far more balanced with the rest of the sound (personally, I find it more boring, though your mileage may vary). The soundstage is about the same (my friend who owns the Dusks says the S12 soundstage quite a bit wider though), imaging is better on the Dusks, and instrument separation is slightly better on the Dusks. I think the Dusks are technically better, though less musical. My friend would have regretted spending more than twice as much on the Dusks if it wasn't for the S12s being too bright.As for everything the A4000s do better: they have soundstage.I've owned the OH10 but haven't listened to it in a few months. From my recollection, the S12s and OH10 have similar amounts of mid-bass but the OH10s have more impact and sub-bass. I found the OH10's mids and highs to be too sharp and shouty, so I prefer the S12s in both areas. Soundstage is slightly wider on the OH10s, with imaging and instrument separation about the same.If you're ok with a little treble spiciness, these are probably one of the best IEMs under $200.

I have a ton of in ears but these are the ones I keep reaching for. They are balanced with a nice v shape. The bass is powerful and tight. Highly recommend.
