Very good, high quality sewers.
I was extremely surprised by their size, they are extremely small, nothing funny about that, on the contrary it's very practical to put them in your pockets, we forget them in our ears because they are so comfortable. The finish is very nice. I'm not sure they'll survive an accidental drop, so I'm going to invest in a protective ear cup. The noise reduction is good but not great, obviously it's not as good as my XM3 but it did the job, I don't blame it.
