This review either takes sides or they fall heavily for advertising slogans of the products. Or they send you the headset they produce best as a sample for review. Anyway, let me get to the point. I also recently bought a QC 2 and everything worked fine and properly on the headset. Only 1 day has passed and the headset has started to show connection problems with the Android application. It was difficult to connect, I had to try to connect it too much. I solved this problem. Afterwards, a continuous sound in the back, such as a white noise inside the headphones, a slight rain outside, or the sound of the wind, began to bother me. I couldn’t figure out what I was sleeping on. Afterwards, I returned it immediately and ordered a new QC 2. The new product had the same problem, this time there was noise in this headset from the moment I first installed it. I don’t trust any of these headphones anymore and I don’t recommend them to anyone. I’m looking for a new high quality headset. I’m open to suggestions.
