For me its headphones unless I like what is playing in the shop (we have speakers in FAI connected to the shop speakers with our own volume control. I like hard rock/metal (Disturbed, Korn, Volbeat, Slipknot, ect...)
We use Spotify. Classic rock radio on a medium/low volume. no explicit music
Sometimes I mix it up with some alternative music (Which is what I prefer). I am the most senior person working in my quality lab (which is sad because I have only been here a year and a half, The turn over is insane) and it is my Spotify account so I just listen to what I want and I rarely get pushback.
