I would think the 'phones output', with the volume turned down as low as it will go (on the walkman), should not overload the input. As already mentioned, the RIAA Eq will make it sound rather unusual, like you turned the treble to maximum and the bass to minimum. Having said that, some digital amplifiers (in the walkman) don't play nice if they don't have a low enough load impedance but the better brands work just fine ...

Surely the RIAA compensation would boost the bass and attenuate the treble ie bass to maximum and treble to minimum?
