Isolation will vary depending on your impressions and fit but outside of that I thought it was excellent – the modules I have not had a chance to compare given this one came with the stock plastic one.

I think both are excellent performers but tonally I have a preference to what the A12 can do and I think the Vision Ears VE6 does what the Roxanne can do only better. Its aso huge in your ear for the amount of drivers given the A12 is much smaller and has more drivers.

You can tune the Roxanne a little so rather than bright vs dark I would say what you are hearing is bass forward or neutral depending on where you hear the dial. In compairson to the A12 the treble on the Roxy is brighter.

Best reference sound is the VE V6XC.

I just bought roxanne ,did you think adel 12 and roxanne in the same level ?
if the treble laid back you mean it sound darker in Adel 12 ,
if the trble is bright why owners of rox. say it dark not bright or natural ?

will you consider roxanne one of the TOTAL iem ? I’m not searching for refrance sound cause most of them is boring .is that true ?
sorry I asked you many questions .

Adel A12 overall for me, it has a nice full sound and the treble is just dialed back ever so slightly to make is a very pleasurable listen. Bear in mind though my Roxanne is the universal variant.

I have not heard the K10 but the A12 is ideally suited to a lot of those genres.

So essentially not harsh but extra detailed- just the way I like my sound :). However, I will probably have to order them before coming to Germany because I can’t afford staying there for weeks until they build them… Unless I can ask as a special favour to get the impressions say Monday and be done by Friday. You just gave me an idea, no harm in asking.
