Nice Job! just take the line out of the "O" its not needed and almost makes the logo appear to have 2 symbols rather than 1 and i would also remove the shadow under the symbol as it will just make the whole production of the logo harder to produce on Stationery and Signage

I think there's a lot happening here. I agree with M@ about the line in the O and the shadow.
You have used the headphones and the bulb to represent sound and light, but the light bulb looks like an (idea) to me. On the first glance it got me thinking why is it used there.

Looks nice. Not a fan of the line in the O too and the grey background.

Good job.

Excellent job. Echoing previous reviews, I'd say the line inside the "o" is unnecessary. May I say I just love what you did there with the bulb and the headset -- integrating "sound" and "lights," genius!

Good Job! I agree with all about line in the "O" and agree with mahayni about the bulb. When I see I remember of idea, not light.
Congratulations for the creativity!!

this is neat apart from the "O" kinda over crowding your logo... but apart from that its neat/clean/original...

props

Nice work! Not crazy about the grey, but other than that it works.

Looks really good! Try new colours.

All the idea is just perfect, for me when its about colors, i would rather use orange and purple, something more reprensentive of events. And respect to the elements i think the design is well made but the line in the O need more work. I would prefer to have less space between all elements and make it more compact: font and symbols.
