Volume Control
The volume control is quite a nice feature as most lower-end earphones do not have a volume control. To see it on this pair of earphones was nothing short of surprising. To be honest, I did not realise it came with volume control until I opened the package. It was a really pleasant surprise for me.
It is quite small but surprisingly easy to use. Some people with larger fingers may have some problems using the volume control because it is rather small and very sensitive. However, you can always leave it at maximum or minimum and adjust the volume from the audio source.

Earbud Covers
The included covers are small, tight-fitting pieces of thin foam. They are designed to protect tiny driver inside the earphone as well as help the earphones stay in your ears . They also boost the bass response a little, as they allow the earphones to sit closer to your ear drums, making the bass more noticeable.
Without the foam covers, the buds themselves look quite good
The covers are a little fiddly to fit onto the buds, even for someone with reasonably slim and dextrous finger control such as myself. But once they're on, they stay on and they are quite durable.

mixed up
Although they do not look particularly tough, I can imagine these little covers lasting the lifetime of the earphones.
