Interesting questions are being asked in this thread - thanks to its author!
I agree with many here...that driver count does not necessarily go ahead with better sound quality.
But then, on the other hand, what is "it" that is responsible for improvement in sq and is "it" still worth the yearly increasing prices that well known companies charge for their flagships?
"It" are slight changes in materials, housings, sound canals etc. They lead to slight changes in sound. Yes, reasearch has to be done by experimenting with these slight changes ...
but do you really think that materials and development costs have gone up to 800% compared to only 10 years ago?
I highly doubt it! Unfortunately.
We are not talking about small price changes....
Only some years ago, IEMs (and even headphones) that costed about 1000 dollars were considered as very expensive. Now 2000 or 3000 seem to be completely "normal" in our community and prices go up to 8000! That is absolutely crazy if you think about the fact, that the technology itself has almost not changed (compared to computers or smartphones, for example)!
Just think about earphones like the EX1000. As you can read in this forum, in the opinion of many, they are still competetive with actual models (of course depending on taste of the listener) and dynamic drivers are just celebrating their „comeback“. They used to cost about 500!
I am almost certain, if Sony (secretly) puts them into a a newly designed shell and sells them again as "new dynamic driver flagship earphone" for 3000 dollar - in our days even a lot more people would Buy them and write here „they sound equal or better than other flagship phones in this price range“. Just because of that new price tag they would have „flagship status“ again.
I think the only reason why we have these crazy prices now is people accepting them and their strive to own the newest snd greatest. This is somehow natural, but I feel recently it has become a bit out of control. IEM-Companies just try out how far they can go by making prices higher and higher....and people are still buying.
That is why, myself, I almost only buy used stuff in these days. And also consider to try out more ChiFi in future...
