I've given these headphones a good work out and I am well pleased with them. I was expecting the noise cancelling to cut all the back ground sound however a very small amount is still there. What ever you are are listerning to swamps that out easliy. There is no hiss as I had with a previous brand. The sound quality is good. They fit my head well and are very comfortable. The controls are good. Time between charges is excellent. They seem to be robust enough - but time will tell. They are the best blue tooth headphones I've had - I'd buy it again

Bought this for my autistic child really great sound very happy

Had these for 2 months, excellent noise cancellation on the plane, office and home when the kids are watching TV too loud ! Battery life is around20 hours between charges if listening to audio via Bluetooth, probably longer with only NC, not checked yet. Controls are simple but easy to use, would have preferred them on the other ear cup. Sound quality is stunning, so crisp and natural, even with NC activated. The storage case is bigger compared to my QC35 (in for repair), they don't collapse as far, but these are so much better to use and the noise cancelling doesn't sound robotic, its' just silence. One small issue is the charge cable is very short, which is just silly, but I have plenty of these cables for Android devices. I like these so much I listen to music wirelessly while at home throughout the day, very light and comfortable, no wires, I leave the iPhone on my desk and wander around the house.
