Just WOW !! what a Bass i get from this headphone really happy with the purchase, i was initially not expecting much from the headphones as a i was comparing with Bose and Beats more costly Headphone but was surprise with the output i got. THanks Sennheiser .Keep it Up!

Had these phones for a couple months now. Bought from harvey Norman on special. Very comfortable Ear Pads that work well when wearing for extended periods of time. Sound quality is excellent no exaggerated bass or tinnyness from the drivers. Stacks up very well against other pairs of headphones in the same price range

I am so happy with these headphones, I think they are so worth the dollars, a great investment. Being able to turn switch noise cancelling off or on is genius. I have never had over the ear headphones before, has taken some getting used to, but now I am used to them I like them a lot.

The good: Bluetooth is great and pairs easily. Noise cancelling works great and can even be turned off if you want.
Headset is comfortable but tends to get a bit too tight after a couple of hours so can't be used for long periods without a break. Does a solid job.
The bad: The microphone is terrible and picks up every little noise in the room and then plays it back in your ears like a horrible echo. People on the other end can hear all these noises quite clearly and it makes it harder to hear you. From the squeak of a chair to even moving your feet on the floor. This makes it completely useless for phone calls.
