I've had the 681 EVO for awhile, and I just got a semi-open from ISK that looks just like the original 681.
This ISK-580 sounds way better than the 681 EVO, has big bass for a semi-open but not as bloated as the EVO, doesn't have the shrill highs of the 681, and only costs $20.
Would be interesting to see if anyone else agrees.
You are right, iSK HP-580 is the new star on the market. I see they are very popular on taobao and I have read on some forums they are really good. Better then their more expensive and but older flagship model HP-980
How do you find their earpads are, do they need to be replaced, and what about the overall quality? And how would you compare them in every aspect to the 681 EVO?
Would be great if you could compare them in sound aspect to the Takstar PRO80, I know you have them :)
