I think the bite block has more to do with stopping the 'Condyle' and 'Coronoid process' part of the jaw moving, both of these can change the shape of the ear canal, for me with universal's some of the time if I open my jaw it breaks the seal.

If opening the jaw causes the shape of the ear canal to change then wouldn't it make more sense to not use a bite block since your jaw remains closed when using IEMs?

It is a dtec low end and a twfk for tweeter duty. This is the same as the heir.4ai and the Westone 4. Crossover choice, housing, and bores will tweak the final result a bit. But it will most likely have a very similiar sound to the two (assuming they aren't like the 4.ai on tour and horribly mismatched).

Thankyou for the clarification.

I have an uneasy relationship with the TWFK.

For example, the UM Miracle can sound marvelously spacious, but on the other hand, the rendition of cymbals is not always convincing.

Obviously, tuning plays a part, too; I do realise that that can differentiate one CIEM from another, even if they use identical drivers, so I'm not implying that use of the TWFK is necessarily a negative aspect of the C4. I'm just saying that it makes me pause for thought and wonder how well it has been implemented in light of my above experiences with that driver.

Also, do please check out that H-F thread I mentioned earlier. It's chock-full of information relevant to this topic.

Guys, sorry for not replying to this thread regularly. This weekend I had other places to be (wedding) and didn't see the whole shenanigan on HeadFi till now.

It's damaging for us that the only Frogbeats CIEM thread on HeadFi has now been locked and it looks like a total shambles. I tried to establish some middleground with the HeadFi mods but it seems that any sort of compromise would have been breaking the ToS. I don't want any special treatment over other companies because then it all gets out of hand. It seems we're in a pretty bad situation with us not being able to get attention to our products on HeadFi and therefore if there's less interest there's a much less likelyhood of us being able to afford sponsorship so we can do proper threads like we have wanted to. Sad times, really.

Anyway, as there are a few questions posed to me here, I will answer them as effectively as I can.

Firstly, @ HeadfiSchmedfi

1. No, none means that the faceplate colour remains the same as the shell colour, which incurs no additional cost. Any other faceplate colour and you incur an additional cost.

2. We offer clear shells as an additional "out of menu" option. The reason for this is that getting clear shells properly done without a tinge or yellow etc is a much more complex process than basic colour mixing. We do offer them, they just cost more than the selection of colours we offer. It takes longer to do and so we can't offer it as a basic option.

3. We mean B). I wish I could supply an image of it, but we haven't had any build requests for them that have been completed just yet. Hopefully we'll have a clear image of them within the next few weeks.

4. The same colour as you select for the shells. As it stands if you leave everything else untouched in terms of options for the CIEM, you will get one full shell colour (including faceplate and canals) of your choice, with cable, carry case, cleaning tools and gold frogbeats logo. If you choose to not have a logo you can do that at no extra cost.

5. Do you mean the bottom part of the CIEM being clear or the inner canals as you pointed out above? If you are referring to coloured canals like so:

Then yes, we offer that. I will add that to the options today.

6. Not a problem. For all clear shells it's an additional $60 on top of the basic configuration. If you want coloured canals on top of that it would be a total additional $100 on top of the basic configuration.

I appreciate your constructive criticism and could not agree with you more about the situation. We need to make the ordering process a bit clearer and finalise all the ordering options. Above each option we will describe what exactly each one does and how it affects your final design. That should help out in any case.

It's been a tough system to build to make sure it's both intuitive and easy to use and it's getting there slowly but surely. There are a few errors I'm still trying to brush up on with regards to the currency rates (you may hit an error page every now and again as the currency rates fail to refresh).

As far as the cable goes - it's a westone compatible socket that we use and the default cable is very similar to the Epic Pro cable offered by Westone.

I will update with further answers later today.
