The headset quality is pretty high, Bass and noise is superb and the noise cancellation is great.
However the headset has two flaws
1 – Restricting on the ears – If you wear glasses like I do, You'll find the pads push against your ears and therefore pushing the frames into the side of your head. After a few hours this can get quite painful
2 – Tangled cords – This is a repeated issue I had with my old pair of these, The cable tangles frequently and by itself, It does this mainly around the volume adjuster and it was the reason behind my last pair breaking
Overall – Good, However if you have the money, Get a better pair of headphones with cables that don't tangle by itself.
