Product visibly good qualities despite a default I think of conseption (cache protection that left earphone really want bad compared to the right). The sound is stunning on its quality. I bought it for my husband who has played COD PS3 and despite its very good home theater is delighted with his sharkoon. Another small weak point, all the records are in foreign languages, given the number of connections to and most complex that setting, one is forced to go rummaging on the Internet. In short I highly recommend this product because despite its small défaults remains a product of very high-grade.
