Hey guys. So I have owned my EarSonic SM64 v2 for the pas t 1year + have listened to them for about I'd say almost 70 hours total. I love them, I really do. Being in NYC it's a gift to have such IEM that isolate the sound from the outside world. I own the PFE 112, EarSonic SM64v2 and AiAiAi TMA-1 (not IEM) and switch between them. I don't carry my ES much because I get scared I might break them or something. So have taken them out only 2 times in the real world. My daily driver are my PFE 112 and TMA1's depending on the mood. I want to know for those who have owned, used or tried the SM64's what would you say is the next step up and worth upgrading to? I will be buying used from here
