i have a é and a 3 , but i do not use them anymore. to much noice , needed aerplugs or aspirine, now c5 i can listen to opera while driving without headacheHave any of you upgraded from the Neotec 2, to the Neotec 3? Was it worth it? I have been happy with my Neotec 2. I can get another overseas for a little over $400. Is the $250+ worth it for the Neotec 3?
