These headphones have a great sound and a flat silicon no-tangle cord...it really does not tangle! The cord is plenty long allowing me to place my phone or mp3 player in my pocket and listen to my music.
I really like the shape of the earpiece since they curve downward which helps to stay in my ear. The earbuds are labeled left (L) & right (R) and comes with 3 sets of changeable earbud covers; small, medium and large. The control button allows you to answer your phones calls and end calls without having to touch your phone. The control button is located where the 2 cords meet together.
The headphones have a very good quality sound that is crisp and clear. When I am listening to music on my phone or am busy, it is nice having a hands-free microphone. The mic is clear and does not sound muffled.
