Inexpensive Active Performance
Overall value, portability, weight, SOUND
Bass slightly excessive; clip-on design takes a little while to get used to...
The Bottom Line:
If you don't want to blow the bank but still want good headphones, the KSC-35 are for you.
Overall, this is the best overall value, IMO, for a portable headphone. Small and lightweight, the KSC-35s also sound better than any of their competitors, including the S/Portapros. They have slighted bloated bass, the kind that gives me headaches. The KSC-35s would, too, if it wasn't for their very interesting design. Unlike usual headphones which go over your head, or even the neck-band types, the KSC-35s have no headband whatsoever! They hang around your ear - clip is the word most people use, but that sounds painful, and the KSC-35s are the most comfortable headphones i've ever worn. Ever.
To the most important part: Sound. These things ound great. With only 62 ohms of resistance, they will be driven easily from any portable, including MP3/MD players with low output strength, but will not disappoint with more expensive sources, either. The clip design, as i mentioned above, changes the acoustic properties of the KSC-35s. They are no longer exerting pressure on your ears; they instead simply drape the earlobe. Because of this "loose" grip (when compared to the S/Portapros), they lose some of the boominess in the bass department. They do, however, have a peak in frequency response favoring bass, so bass lovers will truly enjoy these headphones. I prefer the mid-range, and the KSC-35s have a decent midrange presentation, as well a good treble presentation. The excessive bass, while less than the S/Portapros, is still too much to allow the the other frequencies to shine.
All in all, a very active-use friendly design, excellent sound for minimal price, and a superiority over other models in the same price range by the same company (KOSS), won me over. These headphones are perfect for an active listener who wants to get great sound out of his portable.
NOTE: I have been constantly comparing the KSC-35s to the Sportapro and Portapro models because all three models have the same drivers. In fact, the S/Portaprose tend to be highly recommended, while actually their sporty-looking cousin, the KSC-35, sound better! For less!
