So. I did some serious listening with the isurus last night and I have to tell you guys..BURN them in and I am not talking about your average burn in either. I am talking 100 hours minimum and preferably 200hours. Here is the reason why.. I have more use out of my pair than any one of you guys and I have to say. My isurus sound stupendous. Just amazing. I took home my more expensive Sony EX41b..And when I switched to the Sonys.. Wow the difference. Everything I try after the isurus now has a flaw minus my EX600. But even then I think I actually prefer the more fuller sounding mids over them..
I know many of you guys were ready to give up on these but I am telling you. I have mine on permanent burn and it has close to 200 hours of burn and use on them and they sound just awesome. Smoother doesn't describe them at this point. What was once peaky highs now are controlled and give me some really top notch precision, clean highs. The bass is just perfect on them and the mids.. I like to test a variety of vocal tracks that reach lows to the highs and once I changed up to my Sonys. Lets just say I am gonna have to sell my EX41Bs. These have been a big disappointment for me. The MP8320s are better than them at 1/5th of the cost..
I know many of you are thinking these wont change much but I am telling you what I hear from them are not iems that even come close to what we payed for them..I encourage everyone that just got an isurus to keep them on a burn cycle and I mean for longer than what you guys are used to. Once these drivers mature you will know what I am talking about.
Look at it this way..Out of box they sound like what you payed for them.. After the big burn they don't. The longer these drivers mature they get better and better.. That is worth giving a try. Give them a good workout and you guys will benefit from a way better sounding isurus.. I had no idea how stiff these drivers were. The only other drivers that benefited this much from burn was my HTF600 and HFI-780s.. Burn away!!!
Update.. Will have 3 new Philips models within a day.. I eagerly await to see how these other Philips earphones stack up to the SHE3580. Will let you guys know very soon.
