Hi, Is the IN2UIT I500b headphones are good? and how much is it?

I am looking to sell my pair. I quite like it but it just does not get much head time anymore. Feel free to PM me if interested :}

Recently I found an old news report (https://goo.gl/K3hQpQ, in Chinese) which mentioned that the LC circuit split the audio at 1 KHz threshold.
 
Also, someone (https://goo.gl/uowIXv, also in Chinese, I501 mod) has changed the capacitor (to Philips 10uF/63V) and claimed better sound.
 
Just ordered some RIFA/ELNA capacitors and will give it a try when the capacitors arrived.

The capacitors have arrived today.
 
Comparison of the original cap and ELNA/RIFA caps:

 
Replacement of the cap is easy:

 
This is how it looks like under the iron mesh:

 
However, the RIFA capacitor seems a bit overkill for T100. The sound is good, but maybe it need some run-in to become significantly better.

So these are back again:

Picked up a pair for $69 and they came in a box labeled with he in2uit branding, which prompted my search here and discovery of this thread. Some interesting 'upgrades' to the overall design. Still burning them in so will get back to folks later if anyone is interested, Curious how things turned out in the capacitor mod above?

Where did you get your T100? I'm looking for one but can only find one obscure Taiwanese shop.
