Hello, I have been using this headphone for 1 and half year. The built in quality is good. the sound quality is above average while the noise cancellation is a bit less. Bass was also not that good.The wires are thick enough and they won’t break easily and now its material covering the earcups started to peal off. But usable.No issue with any damaged parts even after rough use
But altogether its just normal stereo headphones, for this price you can’t accept more from sony.
I would recommend buying this headphone if you are searching headphone at this price range.
Thank you
