Works as designed. Fits quite easily, and I do not experiece a high level of discomfort. Product looks good and goes well with my LG mobile. Sound appears a bit tinny, and sometime crackles. Not sure if this is a defect. People are able to hear me very good, so no problems there. Does pick up a bit of road noise when driving, so would be good to look for something with noise cancelling features, if you are looking around for one to buy.Overall, a decent buy for the money you are putting in. Bought it for less than $30.
