Hey guys I'm new here, I just got the HE-500, how high should the highs be on these? I listen to quite a bit of Jpop and the is a lot of "sss" and "tsss" pronunciation in their lyrics. Even on half volume they are still sort ear piercing. Are my headphones defective or do I just need burn in?
EDIT: I use an Aune T1 amp/dac with an OTK NOS Voskhod 6n23p tube.
Burn in will improve them. Some people will tell you it will help, while some will say it won't. Although most people that have compared a well burned in HE-500 to a fresh out of the box HE-500, like me, usually find a noticeable difference after burn in.
