It's highly unlikely any watermark would come out the other end in any meaningful way if the original watermark wasn't audible.

They why does someone sell a product that does just that?

ContentMarkMP3 is a product for embedding watermarks in existing MP3 audio files. The format is not changed by the watermark, consequently the MP3 audio file still conforms with standards. After watermarking, the file can be played on any MP3 player and is accepted by any MP3 player software that also accepts the original MP3 file.
