For how long have you been using it?

1yr

What is so special that you like best?

Good insulation, cable long enough.

the least?

Serre many heads, even stretched to the max
Its very aggressive, very little true, lack of low medium and high boost
==> 2 reasons why a long term listening fatigue tremendously.

What is your opinion about the value for the price?

The price is not great, nor the quality (do not rely on the look out!)

Knowing what you know now, would you make the same choice? ..

Of course not, especially for rendering sound spectrum is not true.

I note that against this product is not representative of the brand, which makes headphones much better quality than I have already been tested!
