Yes thank you for the response. I meant the source signal being flat, eg. the mp3 file lol.
No, your audio file is not meant to be flat. If it's flat then the vocals and the bass drum and bass guitar would all be fighting for attention with the guitars. That's basically what I said should not and can not be flat. You're quashing dynamic range too.
It's not the file but the way that file is converted into an analogue signal that must, at least ideally, be kept flat, ie, whatever software or hardware you use should not alter what is in that MP3 or FLAC or whatever audio file. One exception is the use of digital EQ to compensate for drivers that do not have a flat response - not that you can make them absolutely flat, but at least make the curve smoother.
I feel I shouldn't go crazy on IEMS because I tend to break the cables in my pocket, or they could get stolen or misplaced(never happened before tho).
Even cheap IEMs like the $20 KZ ZST have detachable cables. And since they're cheap, you can easily buy another one. And the difference between a $20 ZST and a $100 SE215 isn't exactly drastic.
You can probably start with the ZST and then just return them if they don't fit or upgrade later, at least then you'd have some reference for what you'd want to improve on and others can comment if they think the improvements to whatever you might look at for the upgrade is worth the cost.
