headphones are for wankers.
it's solved technology, especially since headphone users have read the eq guide and know how to squeeze the most out of their gear. /hpg/ really is just gearwank
people with multiple pairs only daily drive one, maybe two (an open and closed back) and keep the rest stored in a box. they're autistic enough to set eq for every song and have a hardware eq/tone control that has every knob setting saved in a spreadsheet.
