let me join the club too, mines just got here last friday, don't have much time to listen to these guys yet, but so far, I'm loving em. IT IS the sound that I've been looking for.
i think my akg k67s and k518le, even the k240s were too bassy for me. the bass quality and quantity just perfect for my liking, I don't listen to dubstep, rap that sort of music, mainly rock, alternative, punk. The amperiors are pretty good, vocal and instruments seperation are awesome, I have a modded 555 at home which are pretty laid back, and now I have the amperiors on2go with my cmoy amp, I have to say I'm pretty satisfied
Hate to say it, but the extension cable for me has broken on me somehow. I really have no clue how, but the 90 degree plug is done for internally. Gonna explore a few options. I'd love to get a replacement if cheap. I found it usefully mainly for the amount of room it took up. Otherwise gonna go for a 5 dollar cable and hope it doesn't ruin the sound.
You probably did me a favor. I was going to buy the Amperiors because of how cheap they are refurbished, but I really am not sure I need them since I mainly use IEMs on the go. I have the Vmoda M80s which are good for throw around phones. Down the road I do want to hear the Pro 500s, but for now you've saved my wallet some pain
