Summary: I've bought this item about 3 weeks ago beacause a friend had the same and it was really great! But I'm a bit disapoonted about mine. Indeed, I don't know if it's 'cause I don't know how to use it, but the sound is not really grear compared to my friend's! It's so low that I have to really concentrate myself to hear it! But it is really easy to use! J'ai acheté cet article il y a environ un mois car mon ami a exactement le même et il était vraiment bien!
