I am sharing my one year experiance with this headphone, about sound quality I can say that treble is not good, base is good but not high .the headphones are made up of cheap quality plastic which is strong but not scratch resistant as you can see in uploaded pic there are lot of scratches and the earpads are almost ruptured.i am not happy with the quality, the wire is tangle free and strong with T shape 3.5mm jack. Headphones are lightweight and good for long term and they are expandable, they fit perfectly on ear. At this price the headphones are ok
