Not unless you wire them in series, and considering the size of the dynamic driver the effect would be minute.

I had an opportunity to exchange some thought with Mr Eric Hruza however not recently. He was very informative and helpful guy rather more than just an expert in his filed he is really a passionate.

Very informative.  Always thought there was much more to it than what BAs were used...  I wonder apart from durability and comfort, what benefits, if any, soft silicone brings to a custom IEM's sound, or is it just a different way to achieve a common goal?

 

Which leads me to think...

I'm more concerned that most 'reshellers' reshell pretty much any model of multidriver IEM.  How can they possibly dedicate sufficient time to designing the best possible CIEM around the many principles mentioned in the interview if pretty much every reshelled IEM involves different BAs to start with?  I can understand if one offers to reshell just a few very popular models, but that's not the case with most offerings.  Even more worrying are those who offer to add additional drivers, or should I assume that for the relatively low cost of reshelling, one has to accept these obvious shortcomings?  Like every good product, they're designed to function as a system as close to the sum of its individual parts as possible.

I can understand why Eric Hruza would be reluctant to name names, but by raising the issue at all, he's begging the question. And by not naming names, he's creating unsubstantiated FUD.

I second tomscy2000's post#22 on page 2.

Interesting thread. It actually produced more questions in my mind, rather than providing "everything" I wanted to know about BA drivers.

Hi everyone — so sorry about the buggy links on Where the Market is going parts I and II. Those have been fixed now so have at it. Bummer because those are some of the most exciting parts. Did you know that it takes 4-5 years for Sonion to build out their product line while it takes manufacturers about 18 months. Think about that for a second. That means that they need to know where the market is going 3 design cycles out...
 

Thanks again to Eric for sitting for this,  to Jude for showcasing this on the homepage so that we can all learn more about our favorite hobby and for everyone's great reception to this. Looking forward to seeing this post get 20,000 views.

Well said indeed my friend! Shall we also start talking about custom fit tips for universal in-ears in this post as well. It's the same issue. When you change the canal length, you alter EVERYTHING. Check this out:

I'm sorry but this...

Don’t do it! This is a bad practice for a number of reasons.

Is like saying - don't use comply foams - it's a bad practice. There are many people who would favors custom tips over universal tips ..for a number of reasons.

Of course it changes the sound however in most of the cases it's not a night and day difference. Otherwise why would say Westone offer custom tips - to worsen their product? I hardly think so.

It's more like a tip on designs. My guess it's a continuation on those manufacturers who uses parts from hearing aids and so one. Indeed you can have some similar looking earphone on the paper yet sounding quite different. IMHO it has to do with CSD - how sound travels through time.

So what you are indirectly saying here is universal iem will fit different people differently and with different types of tips provided it will sound different to different people ? So the logic here that canal length will alter Everything is not only for custom tips.
