My lack of hearing has me setting the volume so high that going to the next 5 or 0 up isn't really an option, not unless I want everyone in the house yelling at me, but I cant hear them... because I'm almost deaf and the TV is too loud... so this goes on... you get my point

@Berntley, I thought it meant op didn't want only even or only odd, and instead wanted only multiples of five(which includes both groups, alternating). I don't understand how it's a joke about not understanding math.

@Berntley, I initially read it like Tank:
Odd number? No way.
Even number? Ew, no thanks.
Multiple of 5? Yes please!
Obviously that makes no sense. Equally obviously they meant "*Only* odd numbers? No way."

I always set it to both an odd and an even number, simultaneously.
