Build quality:

Its has a soft-touch finish and does feel semi-solid but where the earcups rotate are so creaky and feels so nasty that they might as well break from just trying to rotate the earcups. Even when considering its only £10, I'm only able to give it a 6/10 as I've had better built £10-20 headphones from others before.

Comfort:

It has a nicely padded headband (probably slightly better than my cloud 2s) but as they are on-ear and how I dislike the feeling of something touching my ears I find them rather uncomfortable. They also trap an incredible amount of heat.

5/10 

Sound quality:

Without the NC on, it has relatively clear mids and highs however bass is literally non-existent. 

With the NC, bass becomes a lot more pronounced and although a little boomy and muddy sounding isn't too bad. However, both mids and highs become rather unclear and 'sloppy' sounding. 

Overall, it kinda sounds like a less-clear, less-controlled, worse separated version of my ST80 (as it has a similar signature) so I'd probably give it a 5.5/10. 

Noise-canceling:

Even with volume cranked up to 100%, I couldn't hear any audible hissing and with my PC fans cranked to 100%, it makes a very noticeable difference in the volume of the fans. In terms of higher pitched noises, with them on, my cherry blues keyboard does sound a little quieter but not by very much. 7.5/10 as it does work without creating any weird pressures or audible hiss.
