I've been racking my brain trying to come up with a name for ya'll, and honestly all the names I see and come up with are corny dictionary words.
Since this headphone is the flagship, and most likely means a lot to the company, I have a suggestion.
Why not name the headphone as a homage to someone really important to the lives of the head (s) of the company.
Maybe a certain influential person you admire, the name of one of your children, spouse, parents, grandparents, role model, favorite artist, pet, favorite place in the world, etc. Something charged with a lot of personal significance that no other person can come up with but you.
