As I mentioned, the tips were the silicon ones that were originally installed (when I tried the foamy tips [comply type?], the sound was dull....reinstalling the silicon ones, the sound came back to life). I didn't mention that the eq on my J3 was not flat (as you probably know, the sound can be tweaked quite a bit with the J3 sound processors) .....the settings were from my previous phones, I didn't bother to change them for the ADV's, because the sound was so good. One other thing, I had been using Mee M-Duo's for the last month, or so. These ARE base heavy. Perhaps, when I switched to the ADV's, the difference made me perceive that their sound was brighter because I got used to the Mee's.....I don't know.
After you mentioned the Ostry KC06, I checked them out, and am now intrigued. You didn't mean the new model, the Ostry KC06A, did you. Amazon has the KC06 for $70.....is that a good price?
