That is a definate "It depends"
The general exposure is that if you set all bands high, they won't sum to flat enough response. Whether that happens enough to bother you is mostly dependent on the technical details of how your player is made.
The safer approach is to add an outboard headphone amplifier like a FIIO E5.
