I used to use earbuds and industrial earmuffs over them. Then I installed some headphone speakers in my earmuffs and wired them to a headphone jack. That worked pretty well, and I used it at work (poked a hole in my pocket for the wire and ran it inside my coveralls out the colar to my earmuffs). Then I used it in a very wet environment and killed it :-(. Maybe I should remake them, this time with Bluetooth.
