@BenF Do you still have the audio file for burning the headphones ? The "White-Pink-Brown Noise (For burn in).wav" link from dropbox doesn't work anymore, I want to burn some headphones but I don't know if that file is a blend of the three noises or they are played one after each other. Could be really helpful to have it.

They are played sequentially.
You can download files from one of these links and play them in loop:

Or you can use this one:

I'm wanting to buy some new headphones. I was looking for the HAS500 but then I got interested in these HAS680, but they are really hard to get (and almost twice the cost of the s500).
I'm still reading all these pages and I've read that the CALs 2 and the Takstar 82 are as good as the S680s, both of them easier to get (ironically around the same price of the S680s).

I think you will really enjoy Takstar GM200 - it's a perfect basshead headphone, read the full review here: https://www.head-fi.org/threads/tak...scussion-thread.849965/page-197#post-15148815
You can find a 5$ discount code in that review, so it will only cost you 56.5$.[/user]

I'm not exactly a bass lover, but I have always loved the bass in the JVC stereo systems, still the HAS500 are around $40usd. I'm probably will have that thorn under my skin until I get to taste the CNTs
Thanks for the audio links.

@BenF
One more question. Does it really worth the extra cost of the HAS680 over the HAS500 ?

Currently the amazon of my country has the S500 in $40 with shipping included, but the S680 are really hard to get.(at a decent price).

@TylerC I would say its a marginal improvement, mostly just comfort and seal.

Sound quality is very comparable.

Just got my red pair back from my wife. Since she got the Mpow M5 she has not looked back. I added dynamat to the cups. Tamed the bass a bit and added some sparkle. They still need eq for the "stuffy" treble. Any bass head would love these. They almost jump off my head with bass heavy music. Definitely a baby SZ2000.

I don't have S500, but S680 was a significant upgrade over S400.
Nowadays there is a much better option though - Takstar GM200 https://www.head-fi.org/threads/tak...scussion-thread.849965/page-197#post-15148815

But how much better ? It's actually $20 usd expensive than the S500
I already have the HyperX Core (which are supposed to be the Cloud II which are some takstar pro 80)

GM200 sounds nothing like Pro 80.
It sounds closer to Fostex TH900MK2, but without the treble peak - see my review at the link above.

Ordered one of these again on January 10th.

Last time I had them back in July 2014, I didn't care for them because I found them overly boomy, but I didn't burn them in using the method in the first post, yet they still had that sweet CNT exclusive timbre that no other headphone I've heard except for the S400 (which is too uncomfortable for me) has.

This time I'm gonna put on some Shure 1540 pads (that should tame some boom right away) and maybe put some cotton in the cups, depending if the treble is resonant or not.

 

[dakanao]

So I just got a new S680.

This unit out of the box, very surprisingly, isn't nearly as bass heavy as the first unit I had back in 2014.

 

[dakanao]

I tried the CAL pads, Shure 1540 Alcantara and Brainwavz Round sheepskin.

The stock pads sound the cleanest, due to the least reflections because they're very shallow.

Anyone in USA still have them and wants to sell it , pm me

Good luck with that!
I have two pair, and I really like them so I'll be keeping them.
It's kinda sad how hard these are to find now.

I Know , it's rare

Maybe try ebay. I lost my opportunity to get the S500's, they are not selling anymore in amazon from my country, neither amazon usa. Although I don't regret my buy, the GM200 are really a nice jewel and I'm planning on get the Pro's 82.
