Pivoting earplates help provide a better fit than most clips.

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.

Ultra-Portable

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.

Specs

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

4.0 out of 5 stars another solid Koss phone February 21, 2005

By dinosauract

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. Even without equalization, though, the sound is quite good. Despite the 60-ohm rating, the 75's are reasonably easy for low power portables to drive. On an absolute scale or compared to the better $50 phones, such as the Sennheiser HD-497, the Koss KSC-75's don't stand out, but for a price of less than $15, these are outstanding. They easily trump any of the included phones or buds with portable players and are easy to transport, due to their light weight and small size. Another excellent, cheap Koss phone.

Update: With more use, I've become more favorably impressed with this phone. Its sound seems to have opened up with more break in. It now is very transparent with a rich, deailed sound - unbelievable for this price range. After a few uses, one gets the earclips adjusted properly to where they go on almost instantly and stay put and are very comforatble. This should minimize the amount of adjustment needed and prolong the life of the clip. Still, the headphone cups occasionally snap off of the clips even during normal handling. But in all, these are an incredible bargain. I would now rate these a five star phone.

5.0 out of 5 stars Legendary headphone value doesn't disappoint July 8, 2006

Amazon Verified Purchase

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.

5.0 out of 5 stars A no brainer for the price. Get them. June 15, 2005

By Birru

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. Considering the ludicrously low price Amazon is selling them for, nobody in their right mind should have any issue with the way the KSC75 performs. They are a noble backup to my Alessandros.

The KSC75 passed my running test. They fit well, they're easily adjusted, and they're secure. They're also quite comfortable. I also can hear enough around me that I'm aware of traffic.

Negatives: These headphones do not offer any isolation, so if you need that, consider Shure or Etymotic. If you're concerned about style, these also may not suit you. It's like you have little, silver UFOs clipped to your ears. Personally, I'm glad they're not available in "mug me white."
