dmtroyerI use them at work and don't get any complaints, but then I wouldn't care if I did either. My cube mate wears ear plugs, but he does that whether I'm wearing headphones or not and nobody shouts over the wall. No problems here.
dmtroyerIf you dont want anyone to hear what you are listening to.. and dont want to hear what others are doing/saying.. Open back is definitely the wrong choice. There are infinite choices for closed back cans in this price range.
