U will find some reviews where they're saying these aren't on the official JBL site but these are on harmanaudio.in . So no worries about its authenticity.

Coming to the quality of the sound its great at this price. Quality doesnot get blurred up even at the highest volume, thing is you gotta use best quality mp3 music and these headphones arent gonna dissapoint you.

The purebass is great. U'll find yourself boucing off the beats.
And the noice cancellation is at its best.

Guys if you'r...

You must buy this. It is very easy to use and the sound quality is excellent. It is simply great for playing games because of the noise cancellation and the clarity of sound. Great for outdoors.

This device is awesome to use. I am giving 5 star to this headphone. everything is fine.
but one drawback is, you will get irritated while travelling because it is wired headphone and the wire is connected to both left and right side, derived in the middle before connecting to speakers.
And when you remove and keep it around your neck, it hurts to your neck like you cant turn your neck easily, because it is over the ear headphone and it is big.
best recommended for gaming purpose and home ...
