What's in the Box
Great but a bit uncomfortable for me on the ears
Great product l, abd amazing customer support when I had issues with my order
Great sound and easy to use. Light and unobtrusive, pairs quickly and so far no dropouts. For me the earpads are on the small side so not for extended listening
Overall good quality with a great battery life.
Only complaint would be the pause and play button which is over complicated and fiddly at times.
Decent sound quality, comfortable fit, you can lay down with these on, but it can get uncomfortable if you wear it for too long. There is a very noticeable delay with them though so that was a deal breaker for me.
