To recap on the early part of the review click here.
I have been able to use these headphones a lot longer and despite their many strengths, the constant background hiss that appears when the noise cancellation is active, is starting to frustrate me. This means I can’t enjoy my music.
Classical songs are a complete disaster. Jazz is just as poor. The only genres that don’t get impacted are dance and heavy bass tracks. So if you like this type of music then these headphones will be fine for you.
However, in conclusion, I have decided to return these headphones and cannot offer my recommendation unless you like bass led tracks which hides the noise cancellation hiss. Of course, you can use these without noise cancellation being active, but then that defeats the whole purpose of these headphones.
