This will be a somewhat compact review and comparison to the HiFiMAN HE-400, they're roughly the same price around here. Starting with some pictures.             Accessories While I don't consider accessories that important I guess I should mention them. K712 comes with a straight and a coiled cable, 6,3mm adapter, and a carrying pouch. HE-400 comes with the stock cable, 6,3mm adapter and a carrying pouch.   Comfort The comfort of the K712 is good. The headphones weight is 235g which is very light considering their size. The...

I got to try these out when my brother bought them for his casual computer use.   The headphones are very light, and have quite comfortable cloth pads and headband. They are made entirely of plastic, which at least doesn't feel to be of too high quality. I can obviously not comment on long time endurance.
