Hey,
I just bought the Sennheiser HD 4.50 BTNC for 200$. While the Noise Cancellation and the battery life are good, the sound really disappointed me. They sound like I'm listening with a sheet of paper in between and the highs barely have any detail, especially compared to my brother m50x. Any Idea why that is? Is it easily fixable or are the drivers just bad?
Thanks!
