Maxell LB-1B Lightbeat Headphones with Flashing Lights

I got my keyboard and none of the RGB lights are working. I tried flashing it with the default configuration but still nothing. What do I do?

the cavalli liquid carbon x , led light , turn red in the middle of a track when i connected it to s.m.s.l su-8 dac. It didnt do it when i connected the amp directly to the computer Did anybody had that problem ? I use the usb to connect the su-8 dac to the computer and balanced cables from the dac to the amp and i connected the headphone with single ended connection

Do the headphones come with a cord? Or is the $45 cord a must if I don't already own a similar one?

I would like to see the headphone frequency response with each set of pads. I would like a better explanation of some of the descriptive jargon. Lower internal reflections: Does this have an effect on imaging, soundstage or what? Tightening the imaging and widening the soundstage: Does tightening just mean better imaging? Wider and more focused soundstage: Is more focused just a better way of saying better imaging? Not sure of difference between this and "Tightening the imaging and widening the soundstage." Tighter soundstage: Relative to original pads? Can you send these pads to outside reviewers so we get more feedback?
