You know, I'm not normally much of a believer in burning in earphones, but I did notice a change in the sound of my CKM's the more I listened to them. The high end does get more relaxed as they break in and lose their harshness and sibilance. Instead of constant noise, I'd put an iPod set on shuffle to the different kinds of music you listen to, and crank the volume up to just about the loudest level you'd ever listen at, then just leave them for a solid two or three days.

 
experiencing and performing the same thing with my Sunrise Xcited now and it's been 20 hours and hoping the treble relaxes even more with further burning.

i guess this is universal for all dynamic iems.

Seems to work a bit for BA's too; I've always struggled with the sound from my SE425's -- I was convinced my first pair was defective, so I got a replacement from Shure. Those sounded marginally better, and out of desperation I set them up to burn in at high volume for about a week straight. I'm still a bit disappointed with their sound (believe it or not, I think the CKM's sound better in many ways), but it did certainly improve compared to fresh out of the packaging. I can't help but wonder if burn-in is proportional to driver size, because I've never noticed much of a change in sound from larger headphones (AD700's) or speakers. The smaller the driver the more the sound changes?

You can meassure the difference between fresh drivers and the used drivers in speakers atleast, so its not really about believing.
For instance, Fs and Cms goes down, but other parameters change too. Its not night and day ofc, but there is some change.

I also am not really a believer in burn in usually, but the marked sibilance of the CKM500s definitely tones down after a while. That or I got used to playing at lower levels. Not sure. Was a while ago when I got these.

I was skeptical on burn in well before joining head-fi, but that OOB sibilance with the CKM500 has gone away with everyone who's bought these. It all depends on the driver, and casing me thinks; burn in affects things more or less depending on those variables.

just received mine made in china lol . 
 

 

[Apo0th3karY]

You got fakes?

 

[Insidious Meme]

You got fakes?

My CKM500's were made in China. Don't think they're fakes.

 

[Apo0th3karY]

Not sure where mine were made but come to think of it, it's likely China too as that's where they shipped from
 
I was just wondering why that was a point to mention in the arrival post? 

 

[audiohurric4ne]

nope . to be honest i do thought its a fake at first , sound sucks 

 but after burn in session for about 20 hours using burn in wave , Im in love with these . thanks dnuts

 

[DrWebster]

Yeah, both my CKM500's and new CKN50's were purchased from a reputable dealer in Japan, and were labeled as made in China. My AD700's were made in China too, and I bought those from Amazon.

Is ckm500 any good for classical?

 

[SikkNazty]

how do these pair up against monster turbine high performance ear buds? (not the pro version)...

 

[jarrett]

They're not very good for Classical. I think the more intimate you want to hear music on these (solo acoustic), the more its flaws stick out.

I settled for she 3590
