Ear Shield Wireless Over Ear Bone Conduction Headphones with 8GB Flash Memory Bluetooth 4.2 Sweatproof Headsets Portable Headphones Outdoors Sporting Earphones (ES-268BLUEP)

I'm not super convinced any music is being transmitted through vibrations instead of the music being right next to your ears but they serve their purpose and I use them daily at a major online retailer warehouse job where we can't have anything in our ears other than ear plugs. It holds all of my music library and then some and as long as I put them on a charger during breaks, these easily last my entire 10 hour shifts. One thing I was super confused about was it wouldn't play music when I transferred my songs from iTunes, turns out you need to convert iTunes files to MP3 first, then transfer which is extremely simple and fairly quick. These honestly have saved me at work, give me something else to focus on other than my back and foot pain.
