As a pair of relatively inexpensive DJ style headphones I feel that the Urbanz Block perform well. In terms of sound quality they are not the best I've ever used but are certainly above average for those available at this price point.
The build quality is good - predominantly plastic but the ear cups (of which two sets are supplied - black and grey) are leather. My main recommendation would be that they are very comfortable (for me at least) and could be worn for extended periods without issue.
One of the defining features of these headphones is the colour - in this case baby blue. Although it may not be to everyone's taste it does help to set them apart from other sets currently available on the market. Overall I would recommend these headphones - but only if the colour was what attracted you to them initially.
