Headphoneus Supremus
A few months ago I was complaining that one of my iem's sounded shrill at times and often unpleasant to listen with and initially thought changing the cable improved them but switched back to the supplied cable and they sounded the same. I'm trying them again with a different source and they sound very good not like before when they sounded discordant and 'spicy' (their graph shows a spike around 7-8k). What could've changed, my ears which can play up, burn in with more use, better synergy with another player though they did ocassionally sound fine with another one, or something else?
