Budget is not a problem but I prefer not to go the top level. Something like 1000 euro can make me think again while there are rivals around 400 500 euros. Give me the best flat iems like UE Reference Monitors. What are the other options?
1 little thing, I prefer U-IEMs with over the ear design, for example like Heir Audio 4.Ai not Ety ER-4 series. This matters a lot to me since I always have a problem with comfort and keeping the monitor in my ear.
