Elgin ear plugs here. They don't last forever and are a little pricey but they are the best option I have found. There may be others they are just ear plugs with a speaker in them nothing crazy but you can actually hear your music they will turn up. A lot of the units that are similar won't turn up loud if they are designed for work it's probably an OSHA thing with the decibels. Think about that.

Muffs are too hot for me.
