or do I need an amp?
If any more info from me is required feel free to ask!
Thanks in advance
P.S sorry if this is this is in the wrong forum!
I imagine the output from the PC audio jack, excluding a soundcard, is going to be quite low for a 250 Ohm headphone. In the end it really depends on the sensitivity of the headphone because even a high impedance headphone with a high sensitivity may sound just fine out of the headphone jack on an on-board card.
