I have been utilizing these earphones for as far back as one year and trust me, if for a minute you overlook the brand of these earphones, they are completely useless. Here are the advantages and disadvantages of this earphones.
Professionals:
1) Excellent nature of the line(Cord is truly long)
2) Cushioned cushions for agreeable situation around the ear.
3) Decently removes all the clamor around by splendidly fitting your ears.
4) Brand name and guarantee.
Cons:
1) Sound clarity is to some degree OK however treble frequencies, esp. metal percussion instruments and "ssss" sounds are over complemented and tend to hurt your ear(even in the wake of modifying the equalizer settings in the music player). This is particularly perceptible at higher volumes.
2) Over-evaluated. You improve headphones at this cost.
3) No mic or volume control
4) Lesser din of volume yield contrasted with different headphones.(Breakdown)
