The title says most. I am wondering, what you would get, if you were me.
The budget is around 350 dollars, and alternatively I can get my money back on my new dt-880, which would get me approximately 350 dollars extra.
I would really like a CIEM, but i am only 17, so i guess it would be a bad idea...
Else i am thinking about getting portable headphones, a new amp or maybe upgrading my dt-880 replacing it with either the hifiman he-500, which i can get at a very good price, or a used beyerdynamic t1. Also the etymotic er4 has sprung to my mind.
What would you do?
Btw, u can see my current setup in my sig.
