Good attacks and rendering good midrange and does not have too much imbalance in the low (no bass hyper tiring). A little regret about the lack of protection on the outside noises, but still allows better control of her speech in foreign language. Comfortable but a bit heavy and tight to wear => but not the ideal helmet quality headset on the mechanical and frequency response. Too bad there is not more on the market with headphones listening back in this category!
