I just bought a pair of BT headphones for use with my 7th gen iPod Nano. Even at the iPod's lowest volume setting (one click above mute), the headphones are too loud. The volume on the headphones is not adjustable. Is there any way to achieve a lower minimum volume setting on my iPod (ideally, to reset the volume slider to a smaller range)? I went into iTunes on my MacBook Pro and created a custom flat EQ in which the preamp is set to -12 dB, but that custom EQ doesn't show up in my iPod, even after syncing.
