its very good headphone i got it in 1400 during sale its bluetooth is working perfectly and battery backup is just awesome however i must say the soak used to cover ear is kinda uncomfortable if you use it for more than a hour your ear might hurt cause its not very smooth soak its kinda rigid however due to that it provide a good cancelation of outside noise but still it could have been made a little more smoother other than that its good and when you also getting 1 year warranty replace
