The Nokia Headset WH902 was purchased 630 Dual Sim for Nokia Lumia. It can be good in the phone plug and seat firmly. The sound quality is good in both the caller and the called party. Only the fit of the in-ear speaker I do not think so successful, at least to my ears. I feel like a foreign body in my ears, what they are basically due to the shape, too. Maybe I'm just a little more sensitive than others. Therefore, I forgive only 4 instead of 5 stars. Price is great. Should time break, I would probably buy it again.
