You have done a good job so far trying to capture the essence of what we are trying to communicate to the designers. We are looking for an edgy, cutting edge look that is very contemporary. Love the ear idea.
Would you be willing to try to execute the following ideas?:
drop any icon type application, like in #37 then, choose a modern sans serif font for "Full Contact" then, select or create a very dynamic font for the word "Audio" & and tilt it up at the end. We really want to convey motion or feeling from one of the words without a graphic add on element. If you want to try this with "contact", go for it!
