I can't help you with the standard-ness of your KSC75, but I can definitely try recommending you on what amp to use based on personal recommendations.


Try pairing it with the LDM+.
My Crossroad PLD should be arriving next week, and I am most likely meeting up PcWork to recable one of my Koss next week too. By then I can give you a full description on how it sounds like on amp.


However, just a brief description on how my KSC75 sounds like on the LDM+. Not recabled yet.

Well, frankly speaking, just by pairing it up with my Philips PSC805, I have to admit it sounds abit strange, with slightly dragged/bloated bass, not very deep and clean. Highs are uncontrolled, overly bright, but clarity and sound quality wise is already showing itself. Vocals are precise and clear, cymbals and mid highs are clean and crisp.

Then I went ahead and took my LDM+ from the box (PS: I didn't like the LDM+ btw, doesn't pairs well with my other headphones), and I thought, ah well, since I might very well sell it, why not give it a try.


Grief mistake man. (as in I won't be selling the amp anymore)

With only one hour of burn in, the KSC75 sounded like a charm! Improved bass control, deep and hard, bloats are totally gone unlike the ones which I hear previously from the PSC805 alone. Highs are better controlled, though still abit harsh due to insufficient burn in. The cymbal and midhighs are brought slightly more forward, clearer and more elaborated, clarity and vocal range wise not much of a difference as of yet. Still requires abit more testing.


But frankly speaking I am the very opposite of Madman.. Not a basshead at all, hence, it sounds good for me that way.

Either way, if you want, I might be bored enough to meet you for a jamming session? Especially when I need to meet Akabane to grab a M30 from him.


PS: LDM+ tends to narrow down soundstage btw. Hence, I find it to work well on the KSC75 which have virtually no, or, to say, very little soundstage. Hmmm... I guess it would work well for the Grados too.. But, that's another story altogether. xD Oh what source are you on btw?

wow thx..reali wish2knw d taste of head-amp..nvr try any amp b4 bt js alwaz smellin(actually watchin) ppl's describes..
wel since u hv d experience wit LDM+, il stick closer on it, n standby to hear frm u for Crossroad PLD since u gettin soon..

emm jammin session..??

u mean LDM+ wont narrow down koss soundstage??

im currently equip wit creative sb live 24bit ext. n a shuffle..usually in mp3 ape flac..listen to almos all kinds of music/songs bt stick more frequent wit instruments thn vocals a litl bit..

Jamming session as in we could hang together and test out one another's setup. Or just yamcha la. I pretty much have alot more to learn, but never really have the change to meet up with PcWork, Uncle Wala and Akabane. Gah.. I wanna rape all their equipments......................... Not literally.

What I truly meant was, KSC75 never had a wide soundstage to began with, hence, LDM+ couldn't cause the Koss to lose any soundstage. (since there is next to none to began with)

If you can, you might want to PM yeah_guyz for his Yulong Mini Eph amp, as I've heard that it pairs well with the KSC75 as well. RM50, not much to lose.

Instruments.. As in classical eh? Orchestra, Quartets and the sorts?
Soundstage wise the KSC75 could not deliver accurate imaging of the field of playing, however, clarity wise, I'd say I'm pretty impressed. (I could hear the audience adjusting their sits on one of the songs I've heard, as I listen to live recordings). As for the bass issue I'll give it a check later in the morning then, see if it's truly too weak. Be warned though, I may be a bit bias as I prefer deep hard bass than strong elaborated ones.

lol..if i hv d chance il rape em al wit ya too..haha..i hv fren who been yuheng place b4 n he say its a must-hv experience..haha
oh ic..jammin session for audiophiles stuff..sure~ bt afte my finals 1st oni i can hv tat journey..startin finals on nex week lol..

mayb i nvr tried any high range soundstage phones b4 but i found koss soundstage quite ok la..lively sounds~

hmm..not reali all in classics altog i luv orchestra a lot..hehe..i mean il usually focus mor or equal on instruments of a songs rather thn vocals..bt vocals are stil important for me la..haha..
btw im not reali alwaz in strings quartet but piano quartet wil do..n i luv grp of jazz vry much too~ tey alwaz brin me into live..haha

koss bass/low is tere i can feel it n i knw its capable to present vry well n dazzle me wit js a litl movements in bass, but wit my previous source, i get 90% satisfy in koss's low instruments compared to IEMs,
i mean wit koss i oni can feel d low instruments standin out mor obvious whn d environment around me is reali silenced enuf witout any disturbin like in deep silence nite..bt i can alwaz simply feel d low instruments supportin d music wit IEM.. even i whn paired wit x3i(which talkin abt clarity), i rather like d sound of koss coz its mor naturely for me bt x3i hv d enuf power of low sounds.. (or i shouldn't compare it wit IEM on bass for certain environment around me??)
emm get me? (sry i knw my words n language is vry shit..)

Yea..is recabled by PCwork and i heard dat he's really busy..So c how lo..Can still survive de..

Hello guys, just have a question want to ask here regarding this earphone, currently I'm using Sennheiser HD437 which is lack of bass and the sound quality is not satisfy my needs, so just wanted to know whether this earphone can win my headphone or not, in terms of bass and clarity? If yes, then probably I'll change it to this KOSS-KSC75. Thank

PS: Why you guys want to "recable" the Koss KSC75? Improve the sound quality?

hmm..im stil vry new in audiophila n nvr taste ur HD437 before bt i can giv my litl own review on koss ksc 75..
afte i paired my koss in ears, i found vry lively n nature sounds..vry detailed on all range of sound, clarity enuf to hear an audience's cough frm a live performance recordings n it capable to present vry deep low bass.., high potential to present a vry vry nice sq..

som recable it for improvin its sq n enable its potential to a higher level tis is wat i heard la bt i hvnt try it la..wil recable it soon..

oni its bad i found so far is high sound leakin.. u can hear outside noise n ppl around u can hear wat u listenin.. bt if ur reali luv d detailed high sq sounds ul sure hv d time to find a silence place to taste it..

since its quite affordable in price, its a vry nice thing to hv a try..

Hi there guys, recently have been lookin for this headphones for a while now, but can't seem to find it. Anyone know where I can get a new unit from? Thanks in advance. Btw i had an old model of KOSS headphones (Big fat ones, used it for CS, forgot the model). It was amazing! Can't wait to get my hand on one of these lil babies.

If you're looking for the KSC75, do PM jiaxun. He's currently bringing em in, though you may need to wait for the MOQ to hit which may take abit of time mind you.

lol pal, thanks for advertising. but no advertising fees for you ya.

well, seriously saying, i can't tell you for sure that there will be next bulk. if there is none, i will get a lot of swearings from our dear LYN members.

Chill bro, I promote good service. No need for advertisement fees lol.
Either way, bulking by itself ain't easy, so I'd understand why you might not want to continue.

I think most of us can understand that however, and most of us are willing to wait for something this good.

good stuff hard to find.

I definitely agree on that. Have posted on jiaxun's post, hopefully can get on the current bulk >.< Anyways i found my old KOSS, it was a set of UR-20s. Now to find a place to fix the cabling lol!

You can try PM PcWork for recabling but I doubt he has time for it. I'm still waiting for his payment

btw, you have to wait for the next bulk.

when will be the next bulk?
