I've done it two ways:
1. Bose over-ear noise cancelling headphones with in-ear ear plugs inside. (Seems like the ear plugs defeat the purpose of the headphones but it really works well!)
2. Earbuds with professional over-ear ear protection.
Both work well but option one is lighter and more comfortable.
