DO NOT ALLOW SUCH THINGS. Yes you can wear earplugs and in fact these are provided from health and safety but they forbid music players on the floor since such a distraction could be fatal.
Your company may differ but I would not risk my life on this one.
I’m considering buying a pair of noise reducing wireless ear buds.
I work in a steel mill and need a pair that have good volume & range as well as rest of bells & whistles that come with them.
I don’t want to break the bank.
