The earphones came with 3 pairs those silicon plugs for different ear sizes. Sound quality itself is fairly decent for the price. The left ear bud works at about 50% less volume as the right. The sound from both earbuds sounds very muffled. The volume control is passive and does not control the device its connected to except when you slide it all the way up, then it will turn up the connected device's volume. I love the zippered pouch, it's great idea to use to keep them from getting tangled. They are not bad but mine wasn't very good and I will be using a different pair of earbuds instead. Thus the four star.
