I had bought the noise cancelling headphones by this manufacturer in December, 2017. By end of March, 2018, the right headphone has been completely disassembled from the rest of the product, making it impossible to use. Next, I tried reaching out to the Customer Support. It was a joke, There is no one answering the customer support phone after trying for two days straight. No one also answered my e-mail. I feel that it is a scam. It is amazing how this product managed to get high technical ratings. Based on them, my husband bought them for me. I would not recommend this company.
