Since I a few months ago a Galaxy Ace bought, which is delivered without headset, I wanted to buy a headset for various purposes. 1) It should run with my Ace. That does it. 2) music reproduction in good quality. There is at least no significant Deterioration is to my Sony Ex 82 headphones. 3) One should understand the other person well and are even well understood. Again, I was not disappointed. Conclusion: The value for money is good, the product does what it should, therefore, have no choice but to award the 5 points to me.
