Indeed, minor drawbacks:
- Spatialization is not great when we watch a film (however it occurs, simply run a multichannel audio test), precision sound is not good;
- There is a small resonant effect with vocals (unless you cut the spacialisation).
However:
- Immersion is really good, especially in the action scenes;
- The bass is excellent and the dynamics in general;
- I soon got used to the resonance of the dialogues, an effect that does not give the impression of having voices glued to the ear as with conventional helmets.
It is always possible to return to Stereo for quiet classic movies (without resonance effect of the vote), while maintaining a good quality dynamic headphones.
In conclusion, with 260 ODR Sony, I kept because it is really nice (comfort, sound immersion). But more than 300 this is still a price to pay.
