Thanks for your reply. So does the Philips have better low end bass, like a subwoofer? Does it also vibrate your eardrum or ears?
First, i am not a basshead.
IMO, the 3580 goes lower and has more rumble, enough for a basshead like you? i dont know, for me? more than enough.
The thing is that, the Fx1x is all about bass, the mids are so way back, recesed, the highs are metalic, The fx101 sounds better but the 3580 goes low but wit hbetter mids and highs.
downside? cable is noisy.. other than that, exelent value for the money.
maybe someone else can help you recomending a iem with more bass than these, whats your budget?
