It is very unlikely that you will be able to drive headphones satisfactorily directly from the Proceed. Stereo headphones typically have impedances in the range of 32 to 100 ohms or so, which is much too low to be driven from a typical line-level source.
The reason I use the words "very unlikely," instead of totally ruling it out as a viable possibility, is that the Proceed appears to have a very low 10 ohm output impedance. Which I suppose might make it possible that they could drive 100 ohm headphones with reasonably flat frequency response and reasonable volume.
But I would not bet on it, and a much better approach would be to feed a line-level output from the Proceed into a separate headphone amplifier. Audio Advisor has a nice looking selection of them, in the range of $300 or so.
