I think the comment earlier about the KSC-75's showing how bad the reviewer's source hardware or source material is would be the most apt way of putting it. I've owned several pairs of PortaPros/SportaPros over the decades (sold 'em off for a profit each time), several pairs of the famed Realistic/Koss Pro-25's (the original "titanium" driver ones in the mid-80s), then the Pro-35s, the Pro-35A (current models), the KTX-1, the KSC-35s, etc.
Anyone that outright says these headphones/earclips suck or what have you has something stuck in their ears and other bodily orifices. I mean really, for what they are, for what they cost, they offer sound quality that is simply unmatched on those and many other terms. I've heard people make statements about Senns in the sub-$100 range, and I bought 'em, and was sorely disappointed in the audio performance compared to the KSC/PortaPros/SportaPros lineup. I've tried most everything under $150 that supposedly is "better" and none of them hold a candle to these things.
Do a simple Kramer mod, cut a whole in the foam, wham bam thank you for ever better sound quality.
The elitism people show over stuff because they spent more money is unbelievable in this forum sometimes (and I've been around years, just under a different account). It's not necessary to have a big price tag for more than acceptable sound quality, I just hope someday that some of the elitist pigs that infest this place get it. I doubt it, but I continue to hope.
As for the reviewer at that link, he's an idiot, of course. As for me personally, I have never once had my KSC-75 clips come apart unless I was separating the clip from the actual speaker assembly, and I work out with these things on, do jogging with them on, ride a stationary bike with them on, stairclimbing, circuit training, etc. I don't know what's up with people that can't use them comfortably as they're not that tough to figure out and bend to fit so they do have a "perfect" fit.
When I look over the posts about KSC-75's I see roughly 98% of the comments being favorable to seriously awesome, the other 2% are the elitist pigs snubbing them. If it was 1 or 2 people, or even a handful of folks saying they were good that might actually count for something. But so many owners saying they're great - and I'm one of them - compared to so few people whining about them and making comments like "too low brow for me" get interpreted as "I'm too good for $20 headphones, bleh."
I wonder...
