Pros:

Smart Hat quality: First the quality of the
hat is decent. Is it double layered of typical beanie materials. 

Speakers/sound: The sound is
surprisingly good. Of course not Bose or high-end headphones quality, but the
sound is not something that I will complain about. They did their job right
pretty well.

Bluetooth connection: Bluetooth range is far
as I thought it is around 20 ft.

Cons:

• These
  are more annoyances, nothing terribly wrong with the product I received at
  all.

• The
  main speaker that is in the box with the battery and the chip is a bit clunky and I can feel it put more pressure on my ear than with the right speaker. But that is something to be expected considering what all is in the box. But I’m sure as technology improves, this will be less of an issue.

• The
  right speaker sometimes slides out of the pocket where it is held and looking for it and putting it back is a little annoying. Can be fixed my sewing just a bit down so the speaker doesn’t slide out as much.

• This
  is a small nitpick but the hat I got came with a brown square instead of a
  rectangle for the control panel, I would have preferred the rectangle for
  aesthetic reasons but it’s fine.
