Hi. I would like some advice for purchasing headphones to use while at work. I currently have a pair of Bang and Olufsen "Form 2" which were about $100 many many many years ago. Since this is at work, I will be plugged directly into my work laptop. I could see maybe getting a USB DAC if the consensus is that those make a big enough difference in this listening set up. This will only be used with Pandora. With the limitation of being plugged directly into a laptop (no special headphone amp, Pandora as a source), what sort of budget should I consider before I start to get limited returns on dollars spent. I think the most I would consider spending $200, but I have no idea if that's overkill for my situation or not.
Thanks!
