Koss KSC75 Portable Stereophone Headphones Reviews


They're comfy and great sounding


Pros: airy sound, punchy bass, forward mids, great overall balance, super comfy design, CHEAP!

Cons: slightly grainy treble, poor build-quality, ugly

I bought these KSC75 clips because I lost my modded Koss UR55 and I read oodles of praise for them online. At first I was skeptical because they are very flimsy looking and they are often compared to the Koss PortaPro which sounds muddy in my opinion. So I tried them on and I was immediately impressed by the overall balance and airy sound. Everything sounds so natural and forward, and it's really easy to separate vocals and instruments. I really like these with pop and rock music. The KSC75 crush the PortaPro. However, I must say that the treble feels grainy at times, especially with shimmering electric guitars (typical in post-rock). Another complaint would be that...

All hail KOSS


Pros: Value, natural, balanced sound

Cons: treble

....... as a young lad, some 30 years ago, when I first got into headphones and placed my order from J&R music world, waited in ernest for that UPS truck to deliver my pro4AA 'digital ready' headphones. I'd just gotten my new technics CD player and copys of police-ghost in the machine, billy idol's rebel yell and dark side of the moon. before cd's all we had to listen to for portable music was via tdk and maxell tape through a sony walkman that were dubbed and traded from friends lp collections. There was only a few cd offerings at first and boy was I excited about the dynamic range of the digital sound and really liked the...

Packs quite a kick for the price


Pros: Light Weight, Great Overall Sound

Cons: Muddy in the bass

I honestly thought I was going to hate these, but I am surprised how much of a kick these give to songs.    Let's get on with the review:     Build   The build is not the best in terms it's steadiness, but it is definitely light weight and extremely comfortable. You will forget you are even wearing them!  On a side note, if you have small ears, these might not be the best as they can slip off.    Sound   Amazing. Simply, Amazing. I can't get over how smooth the highs and mids sound. I kept on cringing at the ASMR videos I watched on Youtube (good thing).  Now, there is a downside. They do not have much bass in them...

Very good "Pices of ****".


Pros: Wow

Cons: Wow and Clips.

First that all, I called them Pieces of ****, because they look incredibly cheap and ugly, but they sound very good.   They are a bit bassy, but the bass doesn't go too deep, its just mid bass, which is good for me. Mids and Highs are in check.   Soundstage is very good, its a step back of my 668B's soundstage.   If that doesn't convince you I prefer them to my Xiaomi 2nd Piston.   The only "bad" point are the clips, they are comfortable but It takes a while to put them on, So you can buy "Parts Express Mini Stereo Lightweight Headphones" on Amazon and use its Headband with the KSC75.   Overall, for 15$ You wont believe how good they sound.

What a bliss to my ears...


Pros: Airy, clarity, comfort, energetic sound, sparkling highs, non-sibilant

Cons: Looks, bit muddier bass

I was looking for some headphones under $50, went through hell lot of reviews here n got confused about everything. Then somehow the browser showed few auto suggestions n I found these gems. I read in almost every review that these are the cheapest n best earclips in the market. Well they are best but not that cheap in India especially when the exchange rates are so high. I got them for $25-$26 shipped to India through ebay. Packaging:- The packaging was good, simple, nothing much to talk about. Build:- They look flimsy n build quality is questionable. The cable is so thin n so ordinary, I have to be very careful while wearing them. Comfort:- When I first wore the , I felt they are...

King of the entry level


Pros: Sound, price, life time warranty, easy to mod

Cons: Design (clip-on system), relatively cheap build material, due to clip-on system comfort issues

They have good old fun sound signature, very engaging and very dynamic. I found mids are a bit too recessed for my tastes and affected by the low region unfortunately however from a cheap can like this, I don't expect the separation of HD800 obviously. Treble is nice, sparkling very detailed and crisp. Bass could be more controlled but it does its job, it has a strong, punchy bass and when the song calls for it, it knows how to give 'boom' effect.   So what do we have here? Very good sounding on ear headphones which can easily compete against 100 euro price range. Is there a problem, you bet! Some people seem to like the design and clip system but I totally hated it. I am currently...

Is there better bang for your buck!? I don't think so...


Pros: Price, SQ, Price, Clarity, Price

Cons: Clips!

If there are better sounding headphones in this bracket, they sure aren't available to the public yet! The KSC75s just might represent the apex before the downslope of diminishing returns.   The sound: Very fun and engaging all-purpose sound. The bass is certainly present, although far from basshead territory, the mids are maybe a little recessed, but they sound just great all the same, and the treble extends nicely without a trace of sibilance or harshness.    Design: Probably the only downside to these guys. The driver covers look super-cheap and the earclips make these the most uncomfortable cans I've ever used. Granted they do get more comfortable as they...

Really nice with amp or full size gear. Not so great with personal players.


Pros: Comfortable. Sound great with amplification.

Cons: Needs more power than typical small player offers. Low power equals poor stereo imaging. Zero isolation, beware hearing damage.

I bought these this week from amazon.co.uk for £10 including delivery. That's US $15. edit: I've changed my rating and feel more positive about these than when I first wrote the review. See the comments after the review. Packaging, appearance, warranty, euro-nanny knows best: Mine arrived in the small European packaging box, branded as Pulse clips as well as "Koss high performance on-ear clips". With the clips came the Koss warranty and the euro-nanny-state leaflet on waste disposal. The phones are the silver plastic Koss branded items everyone knows. The lifetime warranty is valid but irrelevant because shipping costs from UK will exceed the value of the product. But I do very...

Phenomenal for the price


Pros: Inexpensive, fantastic soundstage/imaging, incredible instrument separation, very detailed, textured bass, crisp highs, energetic and engaging sound

Cons: Clips aren't the most comfortable, aren't sexy looking

Taking price into account above all else, these are the best headphones I have ever owned.  Obviously my HD650s and DT880s sound better, but they also cost 15-25x as much. I've probably put ~150 hours on them. I did do the kramer mod (involves drilling a few holes in the driver cover to allow more sound through) but they sound great even without the mod. I also bought a Parts-Express headphone from Amazon, took the garbage drivers off them and snapped the Koss drivers on. I find them much more comfortable this way. As a plus you can bend the headband however you like to suit your comfort level. Some people do the "quarter mod" where you put a quarter over the earpads ...
