well i got mine ostry kc06a last week, still i havent test it yet , hehe, will try it today since its weekend
hope im gonna like it xD

You really have patience
Usually people will unbox and test it straight away when they receive new toys. haha

I was looking at this baby for a while now. Anyone can comment on whether this is a warm or V shaped signature?

Also looking at the Yamaha EPH-100

the most simple words i can describe it now...
OHH MY GOOODDD~

IM IN LOVE WITH THIS EARPHONE!!

Rm200?

what do u mean by RM200?

i think liquidgirl got sell it, 259 each

i bought directly from china, so price is roughly like that

First of all, I would like to talk about the concept of V shape first. According to my understanding, V shape means focus more on treble and bass, mid a bit recessed.
Take GR07 classic as an example, some reviewers think that it's a v shape sound signature. I personally think that, a typical V- shape sound headphone is something like DT990. GR07 classic to me, I do agree it has very extended treble but for the bass part, the quantity is not a lot. At least not enough to make it a V shape. It's more like an inverted triangle, treble on top, follow by mid and bass. Of course, the jargons and words that everyone used in audiophile is not so strict. So sometimes we may be talking about something close but describe in different terms. This is why, audition yourself would be most accurate.

Ostry has 2 babies which are KC06 and KC06A.
Both slightly to the warm side, not as warm as RHA MA750i. RHA is very typical England sound that focus in mids, smooth and rich.
KC06 if compare to GR07 classic, is more V shape. The treble is still with good expansion, not as refined as 07 classic but more watery and meaty.
Bass is much stronger and punchy. The mid is richer and fuller than 07 classic but compare to treble and bass, it's slightly backward.

Overall, GR07 classic is more refined, slim with better details, separation and sound stage. It's technically stronger.
Sound signature of KC06 is very pleasant. Compare to 07 classic, it is more suitable for pop, rock, and EDM music. But in terms of new age, instrumental and classical, 07 classic is more neutral.

KC06A has more mids and bass than KC06 but very close. They are base the same sound tuning just some tiny alteration on certain frequency. KC06A sounds more balance and suitable for more genre than KC06. If your system is dark sound, probably you can go for KC06. On HiFiMan HM901, I find that KC06A is all rounded compare to KC06. There isn't good or bad, just depends on your system.

For the price, they really surprise me especially when they are being burned in less than 24 hours.
Later on, I will test it using ibasso dx50, Fiio X3, Matrix mini portable and other DAP. Will update again after this.

I think PedangGila is talking about KC06. KC06A is at higher price than KC06.

ive found that changing tips the sound stage abit different, more lively (using wooduo silicone tips)

suitable for pop music but not with classical for this headphone, well its just my opinion

try to use abit longer see got any different or not hmmm

leaving my toy all alone... not gonna happen for me...

I was debating between KC06A and Havi B3... in the end I chose the cheaper option

Liquidgal. Maybe you can bring in Havi B3 Pro 1?

One of the first KC06A owners here. Pre-ordered along with mochill in head-fi. Still loving them

Even for classical music alone, different type of classical music has very different requirement for headfi equipment. Just like piano and violin, chamber music and symphony, they require different elements in presentation.
May I know which characteristic of the IEM that you are referring to, that is not suitable for classical? Feel interested to discuss about this
Actually to me, any RM200+ IEM can't really present symphony well. Symphony has higher requirement than other music genre, in terms of pace, dynamic, sound stage, separation, accuracy and so on.
I won't say it is more for pop than classical, I would rather say it perform really well for all genre at its price range. When comes to classical, GR07 classic still outperform it though price does't differ a lot.

Will consider if it's good
don't have chance to audition it yet


ya, I like them too especially the mids for vocal

There are also a few budget phones out right now that are around. The DGS100 hybrid and TTPOD T1E comes to mind, already have the hybrids coming in, I've heard good things about them

Thanks for your suggestions. Will try to audition them if have chance.

I would say.... it isn't considered warm for my ears, nor v-shaped. (they are not even bassy why v?)
Slightly neutral, with a little emphasis on treble and tuning on mids. Rivals RE400 well I could say..

I have been experiment with the ear tips it provided and some of the after market tips, always go back the stock board bore tips for its house sound

Basically i've only got 2 earphones, Sony Z1 stock earphones and this KC06A that i got it from Willy recently.

It's my very first Hi-Fi IEM, so I don't have much experience or skills to listen, below is my vague feedback towards this IEM after using for around 5 days by playing FLAC files via both my computer and my phone.

1. Noise isolation on KC06A is quite weak, i can still listen to my fan spinning after i put it on, but when the music is played, it's basically muffled up the surrounding sound.

2. Compared to sony stock earphone I got, KC06A is much more clarity and better separation than that Sony's but then the Sony somehow have more "oomph" than KC06A.

3. Once again compared with my stock earbuds, the bass is very muddy; where else the KC06A have much more detailed low frequency bass.

4. It doesn't really satisfy my needs on warm tone.

5. Don't know whether is it my ear's shape, It starts to get a little discomfort when wearing for around 30 mins.

This IEM basically satisfy as my very first IEM but then it actually disappointed me a little on certain details.

*I do not have any DAC or AMP in my setup.

1. Yes, the isolation is mean to be slightly below average due to shallow insertion, you can further improve it by looking for triple flange tips. Less comfortable tho (Tried the triple flanges few times, never liked any because of discomfort due to my ears canal shape)

2. KC06A isn't a bassy IEM but your sony is. Extra oomph is mid-bass hump, but the KC06A doesn't have really emphasized mid-bass.

3. I feel it's a little weak for a basshead but yes, detail of the bass extends well and the bass decay is just nice.

4. I don't think its warm.. it must be at least like SE215 then its considered warm for me.

5. Do you wear it straight down? I get discomfort from wearing them straight down but not from over the ear, never used any ear guides.

And also from my findings, tried to play from my laptop/phone/tablet, it had a lot of distortion. Those distortions are practically disappeared by a great margin when i switched my source to better one.

This post has been edited by psychoactive: Sep 10 2014, 02:17 AM

2. Just wondering, do application of Amp able to boost the mid-bass?

4. Never tried SE215 before so yeah....

5. Straight down, the aluminium body somehow poke somewhere near to my ear canal, have to readjust position sometimes after wearing it.

This post has been edited by boiboi95: Sep 10 2014, 02:29 AM

Boost the mid-bass? If you're not a "purist", just soft EQ it.. Nonetheless, KC06A scale well with amplification, I recommend it with a use of amp, and no, amp won't boost your bass unless it has bass boost function (like the C421, C5, Digizoid zo2.3), or hardware eq (e17).
Knew it you wore it straight down lol the angled body is sticking out to your ears i guess. Why dont wear them over the ears?

No idea how to do the EQ; more like didn't dare to touch it

Did asked Willy about the amplification, she did recommend me to get a better DAC or DAC+AMP combo rather for me to get a standalone amp (i dont have a DAC , i was tempting to get a E06 to drive it though) , after the recent purchase of this IEM, I don't think I can buy anything that price range for now , for now DAC costs a lot to me. Summer holiday's ending soon, no more part time for me for now :/

I did tried wear it over the ears, It felt weird for me so i swap it back to straight down

This post has been edited by boiboi95: Sep 10 2014, 02:38 AM

I actually do find the eartips to be a little bit hard for me. to have a more comfortable wearing, can also change to comply foam.
I prefer to wear it over ear than straight in as well.
You can try to wear it this way, and see if it's better.


Earlier on just tested on dap like hm901, x3, the bass to me is quite satisfactory. I do listen to rock and metal.
Just tested again on my xiaomi mi3. I do understand why do you think that the bass is lacking. On hp, the bass quantity is lesser, missing a lot of bass details, too loose, soft and not solid. Treble could also be a little bright.

I guess you need a better source and amp for it. i also not too sure if you really prefer more bass than me. can try the thumb drive size dac cum amp from Stoner acoustics like ud110, 120. Should be within your budget. I heard it support otg too.

Set the 200hz region +4db, then one upper level and one lower level for a +2db. Thus, making it curved like. (Like for my player its 150hz and 280hz, they are mostly different, just find the 2xx hz region first).

Golden rule, garbage in garbage out For Ostry, i feel that they are quite source dependent.
Get some cheap budget USB DAC like the hifimediy or UD130, can even pair them with entry level amp like the one you said, E06. (I do not recommend the E06/E07, must get to at least E11 )

If I get standalone DAC drive like UD110, isn't that I still need a standalone amp to drive it? Or do I not need to?

Will try to toy the EQ later .

I'm too poor/early to enter the world of audiophiles

*And it seems like UD110 is completely out of stock

This post has been edited by boiboi95: Sep 10 2014, 01:11 PM

UD110 got build in headphone amp. Actually anything the headphone out should have headphone amp inside including your hp and computer. just that how good it is. UD110 build in amp is for sure better than your hp or computer.

which means after i get myself a UD110v2 (Less likely to get one due to stock) or UD120, there's no means for me to get an amp right?

And through the review of UD series, i saw that they said about you couldn't control the volume unless you reduced it to 16bit (?) i'm confused with this 1

This post has been edited by boiboi95: Sep 10 2014, 01:30 PM

UD110 is volume control capable. But i strongly advise that you use an amp with it because of the power output and the output impedance.

is UD120 have the same volume control capability? and what will happened if i didnt use amp?

I'm not pretty sure if if you can bypass the build in amp. If can't, pairing it with another amp would be double amping.
Whether there is a need to get another amp? If it can line out, if another amp is much better than the build in amp and you have the budget for it, why not?
I'm not really a UD110 or UD120 user. Just have a chance audition it, and find that it's not bad for the price.

But if you do have budget for both dac + another amp, then you can probably go for DAP like Fiio X1, Colorfly C3.

For the bit rate, actually all normal CD format is 16bit/44.1kHz. 24bit music is not so common unless you manage to purchase or download those files that they extract directly from the master tape. I would think that don't really have to care about the bit rate so much especially for entry level gadgets. As long as it's lossless, it's good enough. The music version (like produce in which year) and production quality are more important than the bit rate.

Probably for now i will get myself a UD120 and borrow amp from my friend.

double amping would make the situation worst right?

This post has been edited by boiboi95: Sep 10 2014, 02:17 PM

May or may not depending on the combination. Sometimes double amping might cause distortion. It's not the normal way of how we set up the device.
You can always test it first

If i have the chance

Hooked up my KC06a with a E07k, everything sounded more towards my preferences a bit (warm + dark). Very satisfied with the current setup

im using ud120 with fiio e11k with kco6a , not bad at all, u should try

I was going to buy UD120, but no amp so might as well for E07k

E07K sounds a little warm and dark for my taste, but overall for its driving capability it should be sounds pretty good for your KC06A.

That's exactly what I want when i hook it up

This post has been edited by boiboi95: Sep 15 2014, 02:16 PM

guys,

i'm quite noob at this...

i have bought KC06A from liquidgal, i have tested out all the ear buds that come along with it, except the one with "red plastic" on it...
it doesnt seems to be big enough to fit...can any user here guide me?

really enjoying it at the moment, i know my previous razer wasnt good, but i didnt realized how lacking it was until i tried the KC06A...
worth the price, IMO...

Wide bore tips works best. Try either Sennheiser double-flange tips(bass is tamed a little but it gives a bigger soundstage) or JVC'S new Spiral Dot tips

really? i'm currently using the larger, softer ear tips...
thanks for the advice, will definitely look into the two tips you recommended...

Let us know the outcome as we'll, after you source for the suitable ear tips

searching for local sellers, but if no choice then might get from ebay...

Finally gotten the JVC Spiral Dot...
i have to say the JVC Spiral Dot fit better than the stock ear tips...

i may not be an enthusiast in audiophile, but the bass on the JVC ear tips sound somewhat "deeper"...
as for the treble, dont really feel much different...maybe i will try out other music...
liking KC06A even more now...


Attached thumbnail(s)

Is this similar to SE215? I dislike sharp/bright trebles. More to midrange and tight bass kind. Suitable? Or is there any other brand/model? Havi B3? AT IM series?

Shure IEM wise, I'm not so familiar. But I think Ostry and Shure should sound quite different.
KC06 is with brighter treble, more to clean and neutral kind of sound. KC06A is warm and thicker in mids with darker treble; bass is tight.

ATH IM50 is with larger sound stage, and good separation, imaging not as solid as Ostry. Bass quantity is more but slightly loosen.

Went to the Stars Picker store today.
Really impressed by the people there! Nice place,atmosphere and good looking girl too.

Bought the KC06A and after using a proper fitting eartip I must admit the sound is amazing.

10/10 would come again

Yes it is very good place to visit and pleasant to buy from them

This post has been edited by liquidgal: Jun 20 2015, 07:30 PM

Will surely come and visit next time. Who knows what to buy next

you have extra jvc spiral dots you wanna sell?

unfortunately i dont have...
one of my friend went to japan last year so i ask him to buy for me...

I'm always on the lookout for good value Chinese earphones, and bought the KC06 after reading its glowing reviews. My benchmark is the GR07 Classic. I found the midbass and mids of the Ostrys to be forward, and treble not lacking in detail, with average soundstage. Having said that the Ostrys are punchy and aggressive to my ears, good for rock and metal, and bcos of the mid-forwardness, good for vocals as well.

The GR07 however, is more balanced, detailed and refined with a wider soundstage. It doesn't have the attention-grabbing bass and mids of the Ostrys, but I found it suits more genres. Ultimately I still preferred the GR07, and used it more often. The more I used it the more tamed the infamous harsh treble was. Eventually I sold the Ostrys to a friend who really liked it for what it was. A worthy little puncher.

Bank in yesterday and receive item today,also very responsive during enquiries in whatsapp,good seller,will definitely buy items from StarsPicker again
