Query: Dull sound

sound quality is very bass and mid centered, so they sound muddy and dull.the highs are compressed too much.they only sound good when you eq your sound source to balance this issue out.the headband gets uncomfortable over time because its not padded...and it squeezes the top of your head for some reason.the whole set is plastic anyway, which is why its a cheap set. im gonna get some better ones soon
