It's just fine, depending on the situation. The customs sure don't feel overly 'subtle' to me, filling out my whole ears... I find many universals to be more comfortable. Same goes for my custom Sonus hearing protectors - guess I'm just a bit more sensitive than average.
Of course nothing isolates like customs. As for the sound, well, there's not that much difference between the $79 Hippo, $300 IE8, $1150 UE11...
I don't have a Fuze, but from all I read they both should have equal SPL. The Clip+ drives even the 64 Ohm RE0 to more or less satisfactory levels (at least for me), so you should not need an amp. Something like a FiiO or CMOY would probably only degrade the sound quality of the very good sounding AMS-based Sansas anyways.
48 hours ago,I read this thread and liked what I saw.
Live in Toronto and found the NuForce dealer was in Ottawa.
Ordered a full kit for an old iPod Touch 1G.
Arrived today and it's a softer sound than I expected...
I guess this is how the addiction starts? NuForce Triplets Sans rubber band Can't beat the small form factor of this amp
Now I am left craving more power,as usual.
Sort of like those people called chiliheads that can't get high enough on the Scoville scale.
Found myself turning the volume up all the way and then was scrolling for the Loudness in the iPod equalizer.
