with very few expected to receive (wait a week, received in 4-5 days) I was surprised by its price / quality ratio who had a loose connection at the beginning, there was an echo when I spoke (a very strong echo !!) after turning off my speakers that were still trendy (and mutated) the problem was solved! ... after a compète helmet look, a 5.1 a bit flat but its still surround to 30 actually one of my best buy on amazon most: -the style -the price -a very good sound quality the only less: -a microphone a little short! (But easy!)
