LETSHUOER S12 Ultra 14.8mm Planar Driver IEM

I like accesories and build quality, shells look very slick, go well with cable (I have cinnamon version), cable is well behaving, not tangly, and without any microphonics. As for tonality, I find it a bit bright to my ears at higher volumes due to percieved peak at approx. 11 kHz (I listen on lower volumes though, so that's not a big issue for my, but some may want to blast it, and this one can be bitey at higher volumes), overall it's very good and close to my prefferences, detail retrieval is very good. S12 Ultra sounds very clean, with substantial bass texture (I would like it to have more subbass, but that would probably be tradeoff in exchange to details), it sounds almost neutral to my ears, without any substantial coloration to sound. Acc. to my opinion it's very good candidate for EQing. Accessories are very good, case is very hard, and it will secure your IEMs at backpack very well. I have recieved with my S12 Ultra also DT01 adapter (USB C to 3.5 jack), cable itself has interchangeable 4.4 and 3.5 mm connectors. I have a little nitpick, DT01 is white, and cable is cinnamon, but it's just small thing (I personally don't care), I had just mention it. Overall I think that's very good IEMs, I have given it four stars only due to the fact that S08 does exist, and even if S12 Ultra performs a bit better technically than S08, I consider S08 to be a bit better in value to price ratio. I like S12 Ultra very much though, I can definitelly recommend it, and it made it to my daily driver top five list.

Bought them 3 weeks ago and use them every day in the office and at home. Really good quality of sound, clear voice, and bass. Also, want to say about materials, the headphones feel solid and are very valuable.

I had them for 2 hours. They are nice. Seem good quality, lots of accessories. Overall pleased with the purchase, but I still need to test them for a few days.

I’ve been using the LETSHUOER S12 Ultra for about two weeks now and I really like it. The sound is clean and detailed, with tight bass, clear vocals, and nice airy highs. It’s especially good for picking out details in music.

Build quality feels solid and it’s comfortable for long listening sessions. Only small thing is it leans a bit bright, so not for those who prefer heavy bass.

Overall, really good IEM for the price

Everything wrong with the previous models? Fixed. These sound wonderful out of the box, feel a bit more durable, and comes with plenty of accessories.
