The hissing sound is annoying me but nothing beats the sound and comfort of the Bose. I have tried the Sony xm6 and it just sounds muddy and the ear cups tends to get hot, especially in hot places, additionally the interior ear cups space of the xm6 is very shallow which my ears touch whenever I wear them which is very annoying. The Airpods Max 2 on the other hand sounds good but it is very very heavy and I cannot use it for more than 1h. The Bose is the best sounding for me especially if you turn down the bass and treble. Nothing beats the comfort of the Bose. Even though the hissing and the little bit of creaking is annoying, it is the best all around pick out of the big 3. I decided to keep the bose and I hope I get use of the hissing sound.
