i have played from a mp3 player in my pocket to headphones. in some cases i use the small earbuds that fit the ear good.. then put a pair of shooting muffs with deep and soft full ear covering pads on.
2X's but now I want to try my "hush" wireless bluetooth headphones, but haven't had the time or inclination because I first have to xfer a bunch of files to my bluetooth phone to play them from. The headphones aren't wireless, but they connect to a small wireless dongle that I can clip on my shirt, hat, or whatever.
My noise-reducing headphones for outside use came from The Sportsman Guide, and my indoor set came from HF.
Both are electronic but as I rarely remember to change those batteries, they're mostly strictly acting passively.
Either way, they lower the ambient noise enough that my "noise-blocking" stereo ear buds/headphones don't have to be ear-damagingly loud to hear the tunes.
The advantage of the dongle-thing approach is that I can change out the headphones/earplugs as needed.
I have been thinking about switching to an electronic noise-cancelling headphone, but the really effective units are too pricy for me.
BTW, for reviews that look at electronics and such from a critical viewpoint, take a look at "The Wirecutter"
