I didn't realise there's a metal strip on the headphones because it's black on the picture, but it's fine. The noise cancelling is decent, but it's similar level to stuffing your ears tightly, but music is able to be heard clearly. Obviously if you want excellent sound cancelling, you need to invest more. It's comfortable to wear all day, and the battery is long lasting. It doesn't quite last the 40 hours claimed, but it's pretty close. A gripe I have is that when it runs out of battery, it doesn't have a notification, it just turns off. Would be nice if there was some way to know how much battery is left. The buttons are easy to use and convenient. The bluetooth is quite effective to about 8/10m away which is nice. Gets a bit shorter when there are walls between though.
