Koss KSC75 Ear Clip
Pivoting earplates help provide a better fit than most clips.
Koss KSC75 Speaker
Plenty of volume with a crisp, clean sound.
Sports Clip Design

A lot of people don't like the full headband on many earphones, but also can't handle earbuds. The KSC75 is a great alternative, with a "sport clip" design that fits neatly--and comfortably--around each ear. Pivoting earplates help provide a better fit than most clips. Soft foam ear cushions guarantee help ensure that you get great sound but aren't entirely disconnected from your surroundings.

Solid Sound

The KSC75s feature dynamic elements for a wide frequency response from 15-25,000 Hz. A two-millimeter titanium diaphragm coating increases rigidity, which means less distortion and therefore more accurate sound reproduction. Neodymium magnets help deliver greater volume, even with low-voltage portable devices, and oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound.


Perfect for travel, the KSC75s include a straight, dual-entry four-foot cord, and an L-shaped gold-flashed 3.5mm (1/8") plug. No need to fold them up when traveling--nothing to fold!

The KSC75s are covered by a limited lifetime warranty.

  • Frequency Response: 15-25,000 Hz
  • Impedance: 60 ohms
  • Sensitivity: 101 dB SPL/1mW
  • Distortion: Less Than 0.2%
  • Cord: Straight, Dual Entry, 4ft

The KSC-75 is the latest edition of the popular and good-performing Koss KSC series. All of these models, the 35, 50, 55 and now 75 are based on the same 60-ohm drivers (also used in the Porta-Pro and KTX-Pro phones). The original model, the 35, is regarded as the standard by which all cheap, portable headphones are compared. The original 35 was a black, clip-on model, built to be very shallow and to fit closely on the ears. It was a fairly nasty-looking, uncomfortable piece, and frequently had problems with its thin foam padding tearing. It was updated to the 50 and 55 models, more "modern" looking silver clip-ons and behind-the-head models. The problem with these was they were significantly heavier, and didn't fit so snugly to the ears. Thus, even though the drivers were the same, the sound suffered a bit because of the loose fit.

The 75 moves a bit closer to the original 35. It is a shallower phone, although still not quite as much so as the 35. It does tend to fit snugly to the ear, which helps make the sound a bit fuller. They are nice and light and are very comfortable. The clip is a different design, it doesn't snap into place like the orignal 35 or hinge like the 50. It simply bends around the ear, leading to two problems with this design. The durability of the thin guage wire could be a problem. Secondly, the headphone cup tends to snap off of the clip when fitting the headphone to the ear. It simply snaps back into place again, but its a nuisance. Once properly placed, which takes a little practice, the sound is typical Koss KSC. The sound is pleasant and full, reasonably detailed and transparent. There is roll-off at both frequency extremes, although this can easily be corrected if your player has an equalizer.

Others have hailed these headphones' "bang for buck" value, and they are not wrong. Inexplicably, 90% of the headphones on amazon.com seem to have 4-star ratings (which can make it difficult to choose, and is hard to understand as the lions' share of consumer-grade headphones are *terrible*), but these are actually the real deal. These literally famous headphones are unquestionably the best sounding thing you can buy for this money. In truth, they are not *quite* as good as the KSC-35s they replaced (which had a bit more bass and were slightly more expensive), but KSC-75s really sound *incredibly* good for the money. Seriously.

You can pick the looks apart or the clip mechanism if this type of headphone isn't your cup of tea--but if you're evaluating raw sound it's *amazing* how good these sound for the price. So for what these cost, stop shopping and just buy these right now.

KSC-75 is the budget headphone king.

Getting an iPod is what finally made me look into spending money on decent earphones. I first tried the Sony EX71 because friends said good things, and well, they were white. And they definitely sounded better than the stock Apple earbuds. More (but not necessarily better bass), better midrange, and the nice bonus of some sound insulation. I was satisfied.

As a consequence, I ended up doing more headphone listening at home too (apartment+subwoofer+late night=eviction), so I did some research looking for entry level performance headphones for home use. I ended up getting Alessandro Music Series One headphones (basically a Grado SR125 with mellower highs - also great headphones). The Alessandros were a revelation, as my first serious headphones. The Sony EX71 suddenly became a joke.

Well, after much research, one name kept coming up when it came to nice, cheap portable headphones: Koss. Many models were recommended: KSC35, KSC50, KSC75, PortaPro. I settled on the KSC75 as they're small clip-ons, and they were supposed to have a nice adjustable fit, in addition to fitting securely. I was skeptical though, as they were less than one third what I paid for my Sonys.

The KSC75 looks cheap. I wasn't impressed. But I have an open mind, so I gave them a listen. These suckers can rock! They deliver a really full sound, surprising for the size and price. They absolutely trounce the Apple earbuds and my old Sonys. And not by a narrow margin. The bass is impressive, and commendably tight. The midrange has real body to it. And the highs sound pleasing too. They also improve with a headphone amp, so they even have a little room to grow. I can't imagine anything under $50 sounding better. They don't really have any serious sonic faults in the $50 and under range.

The Koss KSC75 are a comfortable and versatile set of portable supra-aural (on the ear) headphones (or "cans" as audiophiles call them). They use the same transceivers, have the same Ohm impedence level and some of the other features that the Koss PortaPro offers but they are lighter weight and seem to be designed for the "on the go" lifestyle. (I have reviewed the PortaPro cans; you might want to check out my review of them as I gave them five stars. They are still going strong.) At first listen, the KSC75 sound as good as their five star cousins, the PortaPros BUT BEWARE. I have two sets now that I have to send back to Koss for replacement. Thankfully Koss does offer a lifetime warranty on these headphones but you must submit payment for shipping the replacements back to you from Koss as well as writing them a letter detailing problems, all to be included with the defective product, which you ship at your own expense.

It should be noted that I do not listen to bass heavy music but rather my primary musical choices are what I call the "three C's and one B," which is Christian, Classical, Country and audioBooks. I do not use loud volumes or sub-par products with whatever set of cans I use. But with both sets of the Koss KSC75, at least one transceiver (Left on both sets and Right on one set) began to produce distortions such as warbling, reverb and echo within a week! It would seem that using the superior quality transceivers of the PortaPro model in a set of clip-ons with a lot of plastic is not a well-thought out design.

I've noticed that these headphones have decreased in price since I purchased them. I believe people are starting to catch on to their draw backs.
