These cables have been well designed as the 3.5 mm jack has a screw fitting, which means it cannot be inadvertently pulled out due to over exuberant stage activities.
It is exactly the right length Too short would be unusable, too long would not solve the 'tripping over the cables problem!), and the quality seems to be good, if anything the cable feels a bit thin, but there have to be sacrifices in order to put a 3.5 mm plug at one end! This does not appear to make any difference to the tone to me - but I am not one who obsesses about things like that.
In short this does everything I would expect it to.
