Great noise cancelling except for drivingArvosana 4/5
These are great headphones for airplane in terms of noise cancelling performance. The sound is great although little bass heavy with default EQ setting, but adjustable).
The main con of these headphones are the artefacts produced by the noise cancelling algorithm while driving. You can get rid of the artefacts by turning every noise cancelling feature off. I thought my pair was defected first, but the second pair behaved exactly the same way. I hope Bose will fix this at some point with firmware update without sacrificing noise cancelling performance.
Another con are the controls. Changing from one mode to another is slow volume control is ok, but would be better if implemented using buttons like in the earlier similar Bose models. Turning headphones off is hit or miss.
If good sound, noise cancelling, and comfort are your main priorities in choosing this kind of headphones this product is a good choice.
