Wow. After having plenty of conversations, my order was canceled by
AE and now OPA Store sends yours.
Does that mean they had only few or maybe only one? Or they were waiting for mean customers like me to get out of the way?
I'm seriously tired of dealing with such stores so I'll keep ordering from reliable ones.
Have a nice time with your two sets of A7s. It'd save you time to keep them in the most opposite character by adjusting the switch, filter and treat them as different IEMs. Also it would increase their lifetime cuz I'd be scared to switch the filters repeatedly until I start having problem with the screws.
IImagine you have two sets of LZ A7s and you show it to your friend. Your friend says 'Why do you have two of these?' and you say 'Well, actually they're not the same, they're different!'
