Review: 音質がよく、使いやすいので、リピート購入しました。このシリーズは、アダプタを形状が微妙に違うので、購入前に十分チェックが必要です。
Review: The best! It offers USB - A (the old school connection) and usb C (new form). Also, I love the fact that if it’s muted, the red light is very visible. When someone is talking, the green light is on. It produces the most crisp and clean sound in comparison to all other device devices, especially when you pair up with Poly/Plantronics EncorePro 720 headset.

*by F***O on September 24, 2024*

Esta maravilha serve para trabalhar. Tem adaptador de 4 pinos, não confundir com a de 6 pinos encontrado no DA90. Garante qualidade de som de microfone, silêncio e sem ruído elétrico. Pontos positivos: - É usado em ambientes ruidosos de Call Center. - Tem adaptador QR para utilizar com headset plantronics. Ver abaixo recomendação. Pontos negativos: - Quem sabe o que está a comprar não encontra nenhuma falha, é perfeição pura. Resumo e recomendação: É mesmo difícil por vezes encontrar estas maravilhas no retalho para particulares fora do comércio empresarial, mas encontrando, valem o preço, porque fazem maravilhas pela qualidade de som dos headset que se usa para trabalhar. Os melhores headset compatíveis são os EncorePro HW720 - POLY. Eu coloco aqui esta recomendação, porque não é fácil o utilizador comum dar de caras com equipamento compatível de qualidade. O adaptador de 4 pinos serve para isto.
