Terrible sound quality. I was told I sounded like an alien on the other end. My husband and I both got one and were testing between the two of us to see whether perhaps only mine had a defect, but it was the same with his headset. However, the customer service was great and easy, I called the next day, got the RA number right away without any questions, and we got our money back (including shipping) very soon after we returned the product.
