The sound quality on these is very good. The pairing process and connectivity is also seamless. They connect in an instant without fail as soon as you take them out of the case.
Major problem is the unresponsive touch controls. They just never seem to work right and you always struggle to get the correct command. You have to be very precise with your timing to differentiate between 1, 2 or 3 taps and you get the wrong command about 30% of the time which is very frustrating. Was just easier to use on the phone after a while. I'm not sure if the touch is not sensitive enough or the touch area is too small, but feels like you're pushing them into your ear with every press.
Noise cancellation is nothing special, introduces a slight hiss which can be annoying.
Also my pair had a faulty case which kept fully discharging after 2 days even though I had 3/4 battery level so when I went to use the earbuds the case and buds were completely dead. This has happened twice in ten days. Had to request a refund.
