Verified Purchase(What is this?)
This review is from: Samsung In Ear Headphones with Microphone and Remote for Samsung Galaxy S4 - White (Accessory)
Got these quickly and they are the same as mu original Samsung earphones but the listing says they come with three sets of earbuds (different sizes) and sadly mine came only with one set included.
I prefer the smaller fit as the normal and large are uncomfortable in my ears. Dissapointing but I think I have some spares at home.
