Conclusion: If you are on a strict budget, you won't find better headphones than the Koss KSC75. Still, their headband-less design won't be to everyone's liking, even if they are comfortable to wear. The open design helps audio quality for you, but allows those nearby hear what you are listening to.
Pros: Excellent sound quality, Great value, Lifetime warranty
Conclusion: These headphones may only be $20, but they are definitely not worth the investment. The design is awfully constructed as they fall off of the ears when you move. In addition, sound quality is at a bare minimum.
Pros: The only good thing about these headphones is that they have a retro design and are cheap.
Cons: The only good thing about these headphones is that they have a retro design and are cheap.
Summary: Had these, but sold them when I got a pair of KSC50, which gave me a much more enjoyable and clear sound.
The KSC75 had very little bass impact, cut-off early in the treble, poor detailing in the sound.
Summary: I bought these this week from amazon.co.uk for £10 including delivery. That's US $15.
edit: I've changed my rating and feel more positive about these than when I first wrote the review. See the comments after the review.
Pros: Comfortable. Sound great with amplification.
Cons: Needs more power than typical small player offers. Low power equals poor stereo imaging. Zero isolation, beware hearing damage.
Summary: I bought these after reading so many positive reviews and I must say it's disappointment for me.
I tried them on Lenovo X3A40, Xonar ST and Xonar ST + Dispre v4. Many people says they are balanced with nice voals, highs and not so good bass. Well bass is ok for me.
Pros: cheap, comfortable (with wierd ears), good for rock music, details
Conclusion: If you are looking for a great set of headphones for use with your laptop or MP3 player, you can’t go wrong with the KSC-75s. They are ideal for working out or walking down the street to class. While the aesthetics could be slightly improved, the sound quality for the price is second to none.
Summary: I am gonna start this where it should. These are the best thing in audio I have found at the price-point. I recently took all the headphones I have access to, and basically did a shootout. For audio quality, these came in third out of about a dozen.
Pros: size/weight, price, sound quality, comfort
Cons: build quality, on-ear (could be positive?), cable
Summary: First that all, I called them Pieces of ****, because they look incredibly cheap and ugly, but they sound really good. They remind me a lot to the 668B, both have a fast bass that lacks Sub-bass (On the KSC75 that lack is worse), both have a sort of dry timbre, and both have great highs (Depending...
Summary: If there are better sounding headphones in this bracket, they sure aren't available to the public yet! The KSC75s just might represent the apex before the downslope of diminishing returns.
The sound: Very fun and engaging all-purpose sound.
