Entry #2 is very interesting and we like it. I would like to see what it looks like with the 'o' in black as well as the other letters so it stands out a bit more. Could you try putting the headphones over all of the words? Could you arrange mobile hearing in the shape of a head wearing a headset?
#77 is soooo close. Want to try a few other variations? Maybe a different color headband and maybe make the cups a little bigger and the letters a bit taller.
This was my own original concept and you have provided an excellent selection for us. Just missing something.
