Good Review, just a thought on improvement.
I think this review could improve a lot if you added isolation into one of the factors as it is a portable headphone review...
It's not necessary, as it is already quite a good review, but I feel it would improve the review a bit...
Also: Instead of writing "first factor" or "second factor" where the number rating shows up, try using "portability" or "Sound Quality" instead, as it might confuse a few. I see you started labeling with something other than "_____ factor" near the end..
Thank you for the input, will work on it ^^
This review was nearly two years ago, I hope that my future reviews would be better and my English usage would improve aswell. :D
