Headphones at work


I have a set of HD650's I would like to use at work with my pc and / or MP3. Other than plugging them into the sources, what equipment would I use to realize their full potentail. I have read USB amps may not add much. I could use your advice and consultation.

Thank you in advance.

There's a few portable amps that put out quite a bit of power. I don't have direct experience to say whether they're enough for your 650's, but you could find input on the headphone-specific forums. Ray Samuels SR71B,and iBasso PB2 Pelican are both balanced portables known for their power output. They will not compete with a desktop headphone amp, however, which is the way I'd go if you don't need portability, but they may come close enough. I tried headphones while working and ultimately found them too bulky and awkward while moving around and occasionally having to remove to interact with others. I found I much prefer IEM's, the better of which are quite good from a portable device not requiring nearly as much power. YMMV. It may help to state your priorities and limitations.
Good point, Swamp. Another good argument for IEM's which are the best at isolating.
