I haven’t looked into this topic for a long time, but some people’s butts are still on fire 🔥🧯 LOL!!! 😊

Well, here's another one who is dissatisfied with the too small radius of the heat shrink in the S12 Pro. I hope in future revisions of the S12 Pro the heat shrinks will be replaced with better ones (not so thick and rigid), and the rounding radius will be at least slightly increased. BGVP DMA...

😄 I just love these earphones too much 😍🤪💕 And yes, if you don’t notice something, it doesn’t mean that it doesn’t exist and that it doesn’t require correction 🫵😉 Below is the response from the official LetShuoer representative:

@LetShuoer Audio @LETSHUOER Support And you incorrectly indicate the color of the earphones on the side of the box. Black is shown instead of dark blue. Correct this, please, in future revisions, otherwise it all looks somehow not solid. Yes, I understand perfectly well that these are all...

@LetShuoer Audio @LETSHUOER Support Just compare the inside of the leg/stem of the black tips with the white ones 🧐 In the photos below, I tried to capture the very special cutout that is inside the leg/stem of the black tips, and which, for some reason, is missing inside the leg/stem of the...

If you still refuse this extension at the bottom of the ear tip leg, then at least make a special cutout inside the leg of the white ear tips, which is present inside the leg of the black ear tips 🙏 It also helps to better hold the ear tips on the sound tubes.

Thanks to this extension at the bottom of the leg, the ear tip sits on the sound tube very securely! 👍 I think that even after a certain period of time, the ear tips should still be securely held on the sound tubes thanks to this extension at the bottom of the leg.

I prefer to use the included tips because they are often part of the tuning process. In addition, with other tips the sound often changes for the worse for me. Thank you so much! 🤝

S15?! I asked for a comparison with the iconic S12 Pro)))

Please forward these photos along with a description to the Letshuoer engineering team.

Why not just make a special recess inside the leg for the protrusion on the sound tube, as you did for the black tips? 🤔 This is a completely logical decision 👌 There is another good solution to this problem: at the very bottom of the tip stem you can make a special extension, as done in the...

@LETSHUOER Support And please tell the engineering department or the appropriate team so that in future revisions of the S12 Pro they will add a special cutout inside the leg/stem of the white silicone tips under the faint protrusion on the sound tube. Because after a few months, being...

I would like to hear the opinion of the owners of both of these headphones.

There's no direct comparison with the S12/S12 Pro.

@LETSHUOER Support How similar is the Cadenza4 to the S12 Pro? 🤔

I wanted the LetShuoer staff to hear me. They heard me. The goal has been achieved ✌️😎

Don't worry so much! I have already said everything I wanted ,-)

So use metal IEMs 🤷‍♂️

Interestingly, the new S15 and Cadenza 4 use resin rather than metal as the body material. Metal is used only on faceplates. Something tells me that Letshuoer engineers have finally realized the problem with condensation formation 🤫 Well, or it was just a coincidence 🙄 Be that as it may, I hope...

My goal here is not to fight with everyone, but to make the S12 even better! It’s just that someone clearly doesn’t understand this. Oh well.

Awesome! Thank you very much for your response!!! :handshake:

I am a very ordinary consumer, who, moreover, is not an inveterate audiophile who has tried a lot (I have had no more than 10 pairs of in-ear headphones). But with all this, I did a little research and came up with a Sennheiser IE 600. It took me no more than 10-20 minutes! It turns out that I...

What are you, a psychic? How do you know in what manner I emailed them? FiiO, for example, I wrote clearly and concisely that there is such a problem as the formation of condensation on the sound tube meshes of their model FD5. After which they asked me what kind of meshes we were talking about...

And yes, if the engineers of all these Chinese companies knew about this problem, it is not difficult to guess that they would try to do something about it (for example, they would make sound tubes and meshes from plastic, as in the Sennheiser IE 600). But since no one does this, it means no one...

If this is a problem that has been known to everyone for a long time, then I don’t quite understand why the Letshuoer representative hears about it for the first time, and Letshuoer technical support starts asking me a question about earwax when I write to them about condensation. It seems to me...
