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...)
As of this week we have to use a VPN to stream music at work (cracking down on us to try and save bandwidth). How am I supposed to program without Zeppelin?
