I had tried the Silent System headphones as a user and I was thrilled. So I decided to buy them to use them in my work. They are a versatile and very simple tool to use even for those who do not have technological tools and skills. I use them connected to the phone for example. The company is serious. I requested assistance from start to finish and I am grateful for having received it with professionalism and punctuality. Thanks especially to Mattia, who was able to advise me, give me time to decide if and what to buy, without applying any kind of pressure, and help me complete my purchase, up until the day of delivery. Thank you and good work, now enjoying my headphones 😀
