These earphone tips work really well, especially if they are replacing original tips. They kind of seem to be universal, meaning they are capable of replacing all if not many different types of earphone tips. I tried it myself with some beats earphones and some bose earphones as well as some other earphones. They perform the same way across. They fit nicely in the ear because they come in 3 different sizes. They also sound just about as good as the original. The price is a bit on the high end but worth if you need a replacement set. I'm keeping these just for that reason.
