Well, I've listened to them for around a total of 6 hours, the short listening time is due to the fact that I'm waiting till funds allow a FiiO X5 or a HM-650.
So far, the sound signature reminds me of the LCD-2 quite a lot actually, which surprised me! the major differences being it has a smaller soundstage and a slight tendency to be sibilant at times, though I attribute that sibilance to my Source/Amplification, because when I ran them through a FiiO x5, the highs were smoothed out and the mid range became quite lush.
People say the JH13FP tends to be bass light, that cannot be further from the truth ;-;! I've owned both the Westone UM30 and the Sennheiser IE80, both are known to have quite a lot of punch and depth in the Bass department ( The IE80's have too much bass mind you, which is why I sold them) , and the JH13FP rivals them in both aspects. Clean, Tight, and fast as **** without being overwhelming is what the JH13FP's Bass brings to mind.
More impressions to come!
And please excuse my poor sentence structuring, It's 12 am over here and I've nodded off twice writing this reply.
Bleh.
Making a video review once I get a portable player.
