Sennheiser’s HD 4.50 BTNCs aren’t awful, but they're not all that great. In this market, they don't stand out

Decent noise-cancelling, Smooth overall presentation, Good body to the midrange

Balance skewed toward bottom end, Timing and dynamics leave much to be desired, Not the most detail, Uncomfortable over time
Not happy with the noise cancelling for several reasons:Hard to turn off and on, this takes both hands, one to hold the headphones and one to push both ends of the volume control.

Great build quality.When turned off and wearing them, they provide decent noise reduction, most likely due to the closed cup design.Sound quality is good, I am not an audiophile.Fit is comfortable, I have big ears and they fit over them just fine. Other reviewers have commented on the fit.

Noise cancelling, see the review comments.The captune app does not provide any additional functions, (android).Instructions are terrible, just pictures, you need to download them off the website.
I was looking for a quality active noise canceling headphones as I am attending online lectures, watching video lectures. I am also an audiophile and want great sound quality headphones.
Overall great headphone. Decent active noise-cancelling, the bass good and noticeable, mid decent it could be better, low is there but got lose with the high bass.
These headphones sound great, are comfortable to wear, easy to use and have good noise cancelling.
