These headphones are compact and stylish while still being of an over-ear type: they also seem sturdy even though they are fairly light. Clearly other reviewers found the headphones to be excellent but I have some reservations. There is some noise isolation without the active noise cancelling being switched on. This is good especially for reducing conversational background noise. With noise cancelling switched on, the noise reduction is enhanced a bit, but not so much at low frequencies and then the leakage is perhaps more than might be expected with standard active noise cancelling systems. The headphones needed increased amplification compared to other phones that I have. The sound was also rather "tinny". I got round this by changing the cable for a spare that I had which did not have a microphone. Then, the sound quality improved considerably and it was even better with the active noise cancelling switched on. Finally, I found the headphones to be a little uncomfortable to wear owing to a fairly tight grip and slightly small over-ear cups.
