Koss KSC75 Review

Koss KSC75
Bottom Line

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.


Surprisingly strong considering their price. Many reviewers are impressed with the detail and richness of the clip-on Koss KSC75 headphones, which hook individually over the backs of your ears rather than being attached to a headband. Bass is strong, though some feel higher frequencies suffer from lack of refinement. Sound will leak in and out, so these aren't a good choice for a library.

Surprisingly comfortable. In spite of the unusual design, most reviewers find the Koss KSC75 to be comfortable. Users complain that the ear clips tend to fall off, but Koss has you covered should that happen (see below).


Surprisingly inexpensive. Given their modest price, reviewers are impressed with the clean, open sound that the Koss KSC75 headphones deliver. One nice perk offered by Koss is a no-questions-asked lifetime warranty, which includes ear-clip replacement if you lose them.
