Hi all - question to any who has tried the Rn6 in its universal and custom forms. How much of a difference, sound-wise, does the custom make? I know it might change from person to person, but considering it as my first CIEM purchase (if they don't sell out), so would appreciate any insight!
I don't find the sound between the two very different. Some pros and cons:
CIEM:
> much better isolation than the uni, although with the right tips, uni can isolate too.
> much bigger, though moulded to your ear shape (pro or con, depending on user)
> matte custom finish can take some getting used to (choose gloss finish if you're unsure or have very sensitive ear skin)
> full size ATOM modules are MUCH easier to work with
> fit is dependent on really good impressions. Expect to possibly have to rework the fit once or even twice.
> depending on ear shape and size, you'll feel these in your ears more than you would the uni, if you get a really good fit with the uni.
> easier to get a good seal, and better sound, if the customs fit well.
Uni:
> most important pro - can tweak the sound with tip selection. Can't do this with the custom.
> comfort
can be better than custom IF you get a good fit with comfortable tips. YMMV
> smaller and lighter, much less intrusive than customs
> won't isolate quite as well
> kinetic bass effectiveness will depend on fit, whereas with CIEM it's always optimal.
Hope this helps.
