Is it totally inappropriate to use something like “Nearphones” at work? (office)

local radio makes me nearly physically sick lately, i cannot stand female host voice ups/downs with high pitch. I cannot concentrate on tasks when she is literally screaming. I caught myself trying to cover my ears cuz it hurts. Not all of hosts have same speaking manner but she is main.
Lately i checked out “nearphone” type and was thinking about get one so i could use it at low volume during work and being able to hear surroundings.
Would it be inappropriate or offensive to use it?
