While I would need to experiment with recording some more to determine if it's truly "line level" output, it certainly can power a quality pair of headphones through the 3.5mm jack, and while there may be some faint hissing or extraneous noise in the background, it's totally acceptable and impressive how good it is at this price

most of the modes only enable you to either make number "foggy" noise or all-out scratchy noise.
