This is an idea I have and submitted to Quirky.

Basically if you have a decent headphone you can put your headphone on this thing and turn it into a decent speaker. Also you can put your cellphone on it and make it sound better.
Anyone know how to get to the relax feature on Blender I saw a video on it but forgot where. Got to smooth out where the circle merge.
I think you are talking about selecting the edge loop of the ring and hit the smooth vertex button on the left panel.
Are it may be possible that your thinking of another, do the same with the edge loop and hit the space bar and type “to sphere”.
Cool idea for the head phones, Good luck 
Hope that helps 
cheers,
