Not that I'm going to go custom anytime soon, but I'm still wondering how the sound isolation of custom earphones compares those of universal fit IEMs.

On the UE site, it says both customs and the TF10s are -26 dB. I own a pair of TF10s, and personally I don't find the isolation that good, especially with their default crap foam.

Bump... no one owns both?

Btw also heard that Etys have very good isolation. Are they better than custom IEMs?

I don't own either but I may own a pair of customs soon. Customs should be the best as they are a perfect fit for your ear and fill in every nuc and cranny.

Custom's isolation is much much better than universal IEM, no way about that.

i would expect suctom to be better, but in terms of isolation, are you sure you are getting a good seal? have you tired comply foam tips?

Me???

The generics' isolation depends on the tips used but, yes, as has been reported in these sorts of threads before, you can generally get slightly better isolation (maybe 27-28db, though some have indicated up to 30db) on a set of generics with the best tips for your ears.

And, yes, that's with all the IEMs having the best possible fit.

(Note: you can sometimes improve custom fit (and isolation) by making the fit absolutely perfectly tight - see the Livewires thread - http://www.head-fi.org/forums/f103/l...reamin-259853/ ).
