Finally, I'm able to post some picks of all four headphones and give further details.....I'm talking about
Takstar Pro80,
Takstar HI2050,
ISK HP2011, and
ISK HF2010.
I was doing a quick analysis with several friends for the past few days and here is our results on the sound signatures and different tunings with all four headphones.
And here goes the overall picks we decided for......
1.
ISK HP2011: VERY transparent! Details from one end to the other are incredible on these with the widest soundstage and everyone of us agreed to be the most favored for overall best sound!
No need to mod!
2.
ISK HF2010: They are a close second with a very nice bass response followed by a great presentation on the vocals and crystal clear treble with excellent soundstage.
No need to mod!
3.
Takstar Pro80: All of us agreed that the soundstage are a tad better than the HI2050 and has a bold and rich sound to them, which is due to the modding I did with them.
4.
Takstar HI2050: These are still good for there price, but soundstage does fall just behind the Pro80's and can get a little grainy with fast-paced music, as we all agreed after further evaluation. But, overall vocals and details are good.
Here are some picks with the
ISK HP2011 next to the
Takstar Pro80's.....


Now, here are some picks with the
ISK HF2010 next to the
Takstar HI2050's.....



Finally, here are all four headphones together in sequence:
HF2010,
HI2050,
HP2011, and
Pro80.
To conclude, everyone hears differently and might be looking for a certain signature that either calls for more bass, more vocals, or even more details on top. My friends and I took over three hours of testing and finallizing our results for the best interest and help we can offer everyone here on head-fi.
Hope this helps!
