was 3 years rgulirement I use this headset. Further comfort and relative lgret apprcie is its robustness. But his greatest quality is to be a thundering neutrality (not like the HD 25, more sduisant at first, but less Fidler). It has more low impdance which guarantees a level of riding on all types of devices. A single default, I think, 6.35mm jack adapter that Sony is quite fragile, andTHE screw requires the use of the trademark.
Hatshepsut.
