Thanks for the revision and the new ones.
Green & orange is probably not as good as blue & orange. So we'll keep the color mix of #57-59. However, as orange is one of our main colors, you can probably find a way to add orange into that? The font on your second batches, e.g. that in #78, looks better but is too rounded. May be choosing the font that's in the middle of #57 and #78? Also, the sound wave that represents N inside the logo could be just 1 line with some light coming out of it (like
