I've had some more time with the KSC-75* and have come to the conclusion that, on my computer, via the Auzen Bravura (SET 4), I like the K 314 buds better. The 75 have a bit better sound quality – but more importantly, the 314 are more fun-sounding, not to mention more comfortable. Through the Bravura, the 75 sound a bit too relaxed for my taste, but not bad by any means.
On my cheap Zen Stone mp3 player, however, everything is different. The K 314 sound a bit nasal while the KSC-75 are full, smooth and pleasing. Wonderful.
I rarely take the mp3 player outside, I usually carry it with me around the house when washing the dishes, cooking and things like that. I used to have my lowly Sennheiser MX460 buds permanently attached to the Zen just for that purpose, but the KSC-75 simply decimate the Sennheisers. I'm thinking this might be the new dominion for my 75.
*NO foam pads.
I should mention that, on my computer, I've slightly EQ'd down the upper end on both the 314 and 75. The 75 sound too bright without EQ with the foamies off. No EQ needed on the Zen player, though, and it doesn't have that functionality to begin with.
