Conclusion:
None model was a real "Ahh - experience", as of this "small" "cheap model"
I have been really satisfied with any, because I always feel of immersion and enjoyment can was missing.
At last I know that my bass is of paramount importance, I do not hear loud and therefore expect quite a loudness characteristic, ie a bathtub frequency response.
The here perish mids and highs I find no way, I think the case is with expectations of a headset with similar music taste.
Tastes are different.
The XB bring me more joy than any personally were "Hi-Fi" super expensive headphones that do not begin to reflect the bass so great, or it is not audible.
The workmanship is very good, was of course saved the material. Metal One looks in vain.
The pads are very comfortable and make the XB Series special.
The cables are designed for portable use: Robust, ribbon, falls to the knee
Good strain relief.
I'm excited.
Who wants to follow in other regions price should pre-listening to avoid mispurchases previously necessarily, the little Sony is certainly my good value for money, but full marks.
