As taken from Heir Audio's website: After remolding, it is impossible to match the exact original sound signature. This is simply due to the laws of physics and there is little we can do about this. That said, we do double check our work, and make sure left and right head phones are balanced pre and post remolding. Heir Audio, in no form or fashion claims to “tune” or “match” the original frequency response. Furthermore, Heir Audio is not liable for any damages that may occur to your CIEM/IEM during the remold process. By purchasing this service it is understood that you have read this notice.
And I'm sure this applies to all companies. Unless however, you get your CIEM reshelled by the same company that originally made them, but unfortunately JH Audio does not offer reshell services.
