At least you get to demo before you buy. I've blind bought everything I have, and lost a lot in the process. The trick is, at some point, to stop chasing. If you're someone that needs to try every single IEM that might possibly be pleasing, just make sure your bank balance is ready for the ride!
I feel you bro. I too don’t get to try many, only some iems. Just happened I was able to try some models of EE and 64A brands.
My bank account is already busted with all these EE and 64A purchases. So yeah, will definitely need to stop chasing after this ‘last’ one LOL.
