In the introduction to this review, I would like to say that I am usually rather skeptical about buying products outside of the group, due to overproduction or something else. Headphones usually don't fit me, which leads to problems with the sound quality. But that is not the case with this model. The headphones arrived a week ago in very sturdy packaging that contained the headphones and an adapter that came with it, like it came from Fort Knox (that's good). Pull out the headphones or I have a good sense of product quality. They are light but not cheap. In addition, the extension bar fits perfectly. The sound quality was pretty good considering it's outside the band. My only complaint is more personal than anything. The microphone is on the left and cannot be flipped to use on the right. Like I said, personal preference. Overall, I give these headphones a very good rating.
