What do you think?
Welcome to share your experience and opinions for these IEMs.

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

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.

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

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

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.

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.

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.

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

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

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.
