Bose on

Como no so bluethooth no tm nenhuma perda de qualidade sonora. Tm a particularidade de fazer o cancelamento de rudo acstico. Com caixa protectora. Praticamente novos, usados 4 ou 5 vezes em viagens de avio mas agora tenho famlia e no faz sentido usar os fones e estar desligado deles. As they are not bluethooth they have no loss of sound quality. They have the particularity of making acoustic noise cancellation. With protective case. Practically new, used 4 or 5 times on plane trips but now I have a family and it makes no sense to use the headphones and be disconnected from them.
