He actually have a good point. The way he present it though, not so much.

Yeah sort of.

Tips can have a profound effect if there is something fundamentally wrong but my experience is that between tips that fit well and seal well they are mostly fine tuning. Sometimes foam will be significantly different to silicone and sometimes there is no obvious difference. To my ear foam tips suck the authority out of the S12 Pro bass which makes them overemphasised in the treble and all out of balance.

That said, I personally place much more importance on tip selection than the DAC and amplifiers despite that isn’t a popular opinion here.

Also, I see so much talk about cables like they are absolutely a legitimately important tuning consideration but I have never, not once, found any definitive difference in sound caused by a cable unless it was genuinely faulty. I don’t think our recollection of sound is good enough to make a genuine comparison between cables in the time needed to swap them. I have seen a few people try and measure frequency response differences between cables but the results are always within the limits of the test accuracy and the explanation of why they apparently hear differences is that the frequency response doesn’t show everything that effects what we hear, I am not convinced.
I been using S12 pro with my Fiio BTR7 for a few months. I’m a full size headphone user, new to iem. Compared to cost of over ear system, this under $200 iem surprised me.

With Silicone ear tips, if I open my mouth or moving my jaw, sound change drastically. Sounded thin, hollow, not balanced. With foam tips I noticed a small change only, is this normal?

Needed help before order new tips. Thanks in advance for any advice.

Sounds like the silicon tips aren’t getting a good seal possibly because they are a bit small in the diameter.

Some change when moving your face / jaw can be normal depending on the fit of the tips. That is they may seal in a normal facial position but the seal is broken with facial movements which cause the ear canal to change shape.

Try a bigger diameter of the type that is currently working best. If you gave a little information about the type of tips that are working best to date and the size you are currently using that would help narrow down a recommendation for others to try in order to improve the seal.

I tend to aim for a seal that is robust enough so sound doesn’t change if moving my face / jaw but that can mean the tips can be quite full feeling in the ears which can be uncomfortable. It is a balancing act.

Thanks, BS5711.

I been using the supplied white silicone tips, size medium. I’ll try the other tips then. What you’re saying makes sense. Appreciated for your help.

The logical first step would be to try the large size of the same type and see how they work for you. From there you could assess if trying other tips of different shapes was worthwhile to improve things further.

If you find the large work better the below might be worth considering.

These are the best options I have found for IEM on which I need the widest tips to get a good seal and hold.

These have L sizes of 14mm or bigger, the first two are my favourites for the S12 Pro.

Divinus Velvet - wide domed shape and smooth non sticky material, very good - https://hifigo.com/products/divinus-velvet

AZLA Crystal - a little sticky but not so much as to hold grime - https://www.linsoul.com/products/azla-sednaearfit-crystal

AZLA XELASTEC - even stickier, get grubby and deform to the ear canal shape which I am not a fan of but you might like - https://www.linsoul.com/products/azla-sednaearfit-xelastec there is also a new version, don't know anything about them - https://www.linsoul.com/products/sednaearfit-xelastec-ⅱ

Penon Liqueur - sticky material but don't hold grime badly - https://penonaudio.com/Penon-Liqueur-Silicone-Eartips.html

The new Divinus Velvet Wide Bore work very well on the S12 Pro, at least for my ears and preferences.

The fit on the nozzle is spot on and they align nicely with the bore.

It might just be expectation bias but the sound stage and separation seems to be improved over the standard Velvet and Azla Crystal that were my previous favourites.

Is there any info on how wide they are? Have you tried other wide bore tips on the S12?

O primeiro passo lógico seria experimentar tamanhos grandes do mesmo tipo e ver como eles funcionam para você. A partir daí, você poderia avaliar se valeu a pena tentar outras dicas de formatos diferentes para melhorar ainda mais as coisas.

Se você achar que o trabalho grande é melhor, vale a pena considerar o seguinte.

Estas são as melhores opções que encontrei para IEM, nas quais preciso das pontas mais largas para obter uma boa vedação e fixação.

Estes têm tamanhos L de 14 mm ou maiores, os dois primeiros são meus favoritos para o S12 Pro.

Divinus Velvet - formato abaulado largo e material liso e não pegajoso, muito bom - https://hifigo.com/products/divinus-velvet

AZLA Crystal - um pouco pegajoso, mas não tanto a ponto de segurar a sujeira - https://www.linsoul.com/products/azla-sednaearfit-crystal

AZLA XELASTEC - ainda mais pegajoso, fica sujo e deforma no formato do canal auditivo, do qual não sou fã, mas você pode gostar - https://www.linsoul.com/products/azla-sednaearfit-xelastec também há uma nova versão , não sei nada sobre eles - https://www.linsoul.com/products/sednaearfit-xelastec-ⅱ

Licor Penon - material pegajoso, mas não segura mal a sujeira - https://penonaudio.com/Penon-Liqueur-Silicone-Eartips.hthttps://penonaudio.com/Penon-Liqueur-Silicone-Eartips.html
Did you listen to the S12 with PENON LIQUEUR? How was the sound?

Very wide, they flare out from the end of the nozzle as seen in my first picture, wider than any other tips I have.

The Azla Crystal that I was using previously were also quite wide but not quite so much as these. They were good but I prefer the feel of the Divinus in the ear and I believe I prefer teh wide bore over the standard on the S12 Pro in respect of what seems like a touch more open sound.

Like I said, the difference might have been expectation bias because they look so wide I expected them to be wide sounding but regardless they sounded good and fitted me well so at this point they will stay on the S12 Pro.

Worth a try and they might work on other IEM for you. For me they were not a good match on any other IEM but that was down to the way they fit on the IEM nozzle or how they fit my ear on those other IEM.
