Thank you a lot. I think there is a universal version of the Noble 4S that you rated so high in your reviews. At the Noble audio website I can see they have a Noble 4, that I assume is identical in SQ and signature to the Noble 4S or 4C. If this is the case it may be a very compelling option for a mid range/cost IEM with top level SQ and a neutral balanced presentation, as an improvement to the RE-400 and the Ety ER4P. It seems that the Noble 4 is $450 while the 4S is $999, there is so much difference that perhaps thera re more changes and it is just not the equal between universal and custom.
Does anyone know if the Noble 4 is the universal version of the Noble 4S and have the same SQ?
Both are described as identically at the Noble site
If they are the same I may just get the universal Noble 4 now ...
They have the exact same internals without any difference if you wonder whether the custom versions are more special inside. Of course, ciems are harder to make and customize so this raises the price, especially silicone ones like the 4S. Haven't heard the 4S but they shouldn't be too far apart aside from isolation and fit, which of course can affect the sound to some degree. Anyway, the universal version is pretty good and with the 15% Black Friday discount is a very good buy if one is looking for balanced and neutral sound.
