Comes as 2 sets of 2, so ultimately 4 plugs and also a case is in the box. I found it slightly difficult to put in comfortably, not sure if that is because I have quite small ears, so the sizes still seemed big for me. However, i did manage to get them in in the end using a bit of water, but they still did not feel comfortable for myslelf. Did notice a reduction in sound although not as much as id expected, but im ot completely sure they were in my ears properly in order for them to work to their full potential. So for myself personally, i have to give a 3 stars.
