Pelo preço que paguei (R$170,11 em 05/06/22 - Amazon) valeu muito a pena! É extremamente confortável de usar, tem um designe bonito e ótimo acabamento. Não sou perito em som, mas para mim o som é muito bom, tem uma boa potencia e não perde a qualidade em volumes altos. A tecnologia de cancelamento de ruído ativa (NC) é muito boa, não anula tudo, mas ruídos de fundo como motor de geladeira por exemplo desaparecem completamente, além do abafador também ser bom. A bateria dura bastante, já usei o dia todo por dois dias no trabalho com volume alto. E dá para notar o capricho da fabrica, além de bem embalado numa caixa bonita, tem alguns cartões dentro (tudo em inglês), alguns acessórios adaptadores e o mais legal: um case para transportar bem bonito. O bluetooth conectado no celular funciona perfeitamente, mas no adaptador (Bluetooth USB 5.0 EasyIdea) que comprei para o PC ele fica travando o áudio, vou precisar comprar um adaptador bluetooth melhor) O microfone eu ainda não testei...

Pros

  • Conforto
  • Case

Cons

  • Não funciona bem em bluetooth baratos
