I use a pair of Shure prosumer in-ear monitors (recommended by my musician SO) that can double as both earphones and earplugs. When I'm not playing music, I can make out the muffled FA/captain announcements. When the music is playing, that's all I hear. They're very comfortable for long wear and have swappable pads (your choice of foam or silicone in various sizes). The cord can be worn behind the head and tightened at the base of the neck, so they're easy to sleep in as well.
