Build quality is not good, you cannot use it roughly. Its light weight and sound is sweet but no bass or deep bass, overall its not good as compared its price.
It costed me around 599 as I bought it recently from flipkart.com. it use to come with a tangle free cabke but it doesnt come with a tangle free cable.
It got damaged in 1 month. Voice is not coming properly. You have to do like 90s Channel antenna to get the clear voice.
After few days the earpgone stopped working and looked after solution but there was no way to it. Eventually I detected that the aux of the headset has malfunctioned so replaced it with another earphones aux cable.
I would suggest not to go with this earphones as there are many other alternatives such as boat, soundpeats and many more.
