A while ago @meeruf has posted about having lots of fun flying his quadcopter. Not sure if it is similar to the drone you mention. You can read this up. He said he found his perfect hobby for tinnitus flying quadcopter. But each person may be different. Check this out:
Technically tinnitus is a drone inside each of our heads. The size of the drone as reflected on this forum depends on the individual. I am not sure why somebody would want one both inside and outside but to each his own. I am waiting for them...whoever they are....to invent a controller to turn off the drone inside my head. Maybe drones will be the new masking agent for tinnitus.
