We've always loved the long-running Koss 'KSC' series; they simply sound astonishingly great for the money and the newest KSC-75 are one of the best clip-ons in the history of the headphone industry. Ideal 'ear-clip' fit designed for applications where a regular headband headphone just won't cut it like extra-active uses, gym and exercise work, or maybe it's just Mom not wanting to muss up her hair during commutes. These little open-back headphones won't fail to astound with an amazingly clear, rich-toned listening experience at a true bargain price.

The sound quality is quite impressive and the wearing comfort is too on the handy-dandy 'clip-on style', highly portable Koss KSC-75 earphones. We've been recommending this long-running KSC line from Koss for nearly 20 years now, and they've always been the very best-sounding things available on the market at the extreme lower tier of the price scale. The Koss KSC-75 clip-ons are perfect for the extra-active listener needing an inexpensive pair of headphones that you won't have to worry about sweating up at the gym, fitting under your sport helmet or using with that groovy tight skullcap. And since the open-back earpieces won't completely seal off the ear, busy city dwellers can maintain needed situational awareness for deftly dodging traffic on their latest multi-wheeled aggro-toy or metropolitan transportation of choice.

With silver plastic spaceship earpieces and frost-clear ear clips that look rather like 1950s wire-rims, these headphones -- like most other 'ear-clip' category of headphones -- are rather unique-looking and may perhaps feel a bit weird on a few extra-sensitive earlobes; for some listeners, they'll take a bit of acclimation time to get to feeling unobtrusive. The Koss KSC-75 come with a short mobility-oriented 4ft headphone cable terminated in an 'easy-on-the-jack' 90-degree [right-angled] 1/8" (3.5mm) mini plug ideal for iPod, iPad, iPhone, laptops and mp3 players. That standard Koss limited lifetime warranty is always extra-sweet; if they break, Koss fixes or replaces for life so remember to keep our '100% authorized Koss dealer' HeadRoom purchase receipt just in the rare case you ever need it!

Best bang for the buck
Posted by Ninj0r from Tokyo, Japan on 2013-04-20

Recommend Product: Yes
Pros: Comfortable, wonderful sound, portable, amazing value
Cons: Loose for aggressive exercise, sometimes falls off

I bought these to be the headphones to use:
1) with my Android
2) when I'm exercising
3) at work

For $20, the Koss KSC 75's are the best headphones I have ever bought. Great overall sound. Surprisingly punchy and full bass (after looking at the frequency response graph, I expected much less). These easily compare to some headphones I have owned that cost around $50.

They sound great with my Android (HTC J Butterfly), whether playing games, listening to music, talk shows, etc. Very easy to carry with my phone and very comfortable to wear. They perform well in a wide range of situations. The HTC J Butterfly has the built in Beats Audio amp and it works well with these headphones.

For exercise, they do good a job of staying on for most exercises and are light/comfortable. However, if you are going to be training aggressively they will sometimes fall off. I have no problems keeping them on when I jog at a moderate pace but if I decide to sprint, one of them will sometimes fall off.

For work, they are great too. I can listen to them for extending periods of time with no problem as they are light and comfortable. However there is zero sound insulation and some sound leakage so if you are sitting very close to your co-workers and/or looking for headphones that will cut out background noise to help you focus, you should look elsewhere.

Overall, I definitely recommend these headphones.

Just found a new best workout friend....
Posted by Danzspkrman from Victorville, Ca on 2012-06-13

Recommend Product: Yes
Pros: Clean articulate sound
Cons: None, unless you can't do clips

At $40 these things are way ahead of their league, boasting clear artivulate sound reminicent of a pair of Koss Porta Pro headphones I owned in the 1980's. Those things were worth every penny of their asking price of $50 until they finally broke after hundreds of hours of listening while I was overseas in the Navy. They provided a mental health elixer for that time in my life.
Back to this review. Not expecting much from their asking price I expected sound like the Skullcandy Inked earbuds at a similar price, but comparinng the two these have a much more forward detialed almost electrostatic sound. Highs are a little etched, but still would be considered fantastic by any measure under $80. Trying to compare the sound to decent speakers of yore that I would be proud to own in listining space would be like a Athena, Polk or PSB smaller more affordable designs maybe even entry efforts from Martin Login(but not as laid back as the Logins would be), but still holds its own with the bass line, just very detialed, even though they will not go low like a Beats pro....much more accurate involving sound. Feed it a good clean source it will be reveal quite a bit, but forgiving enough for lesser recordings.
I feel this would be a great phone to try the world of world class listening when you have a minimal investment, compare the the sound to like a lower end Sennheiser can which are amazing in their own right, I have a pair of HD 428, that the lovely wife comendered, which have a slightly more laid back warm rounded sound, while these will give you a more open detailed airy sound. Not as sensitive as other some in-ear type phones, but still will play plenty loud with an I-pod, smartphone. If you need it louder than this....find a moshpit... All and all astonishing at double the price, and a great entry into the world of fine listening. Anyone with just standerd issue earbuds...my condolances.

Very pleased but not surprised
Posted by Samuel J from Chicago, IL on 2012-04-05

Recommend Product: Yes
Pros: rich sound, lifetime waranty!
Cons: earclip design will take time to adjust to

Well as of Monday, I have my 4th pair of shorted-out Sennheisers (2 pairs of PX100's, a PX100-II, and HD595). I prefer open back sets for indoor use. I use Etymotic & Shures for commuting on trains & busses. I can't say I surprised that these Koss clip-on's sound so cool. Every review on the internet, including HeadRoom's says so. But still, after spending so much money on headphones over the years, I'm still shocked that I spent under 20 bucks for these. On top of that, they have a lifetime warranty!!! Why don't YOU do that, Sennheiser??? Calling these a value is an understatement. Now, honestly, these Koss KSC 75's aren't able to replace my HD595's, but they don't need to. These are great "entertainment" headphones; they're good for enjoying music, movies, and games. They are tuned as such with strong bass, but at least the highs aren't sacrificed for it. I'll probably end up getting in the habit of EQ'ing them to relax the bass and slightly bump the mids, but even with no EQ these Koss phones are the best bargain I've found yet. These will make EXCELLENT gifts, too!
