I didn't mind the weight. The problem was that the wires were so stiff that, when you moved your head, they would literally clatter as they bumped together. Then, because they were so stiff, the sound would be transmitted through the wires and into the ear cup, and was clearly audible. (So, when you moved your head, you heard little rattling noises - a lot.)
I seem to recall seeing cables that looked like that as aftermarket additions, but I don't recall HiFiMan making a point about what cables they included with the headphones, and I don't recall seeing a picture of the cables before I bought the phones. I suppose they made some sort of deal with some cable maker and imagined they were doing us a favor by including a "high end" cable with the headphones. (I would have been a lot happier if they'd offered a choice of ordinary flexible cables with soft rubber sheaths.)
Cables aside, I thought the headphones themselves, while quite heavy, were really VERY comfortable. I finally sold them because, while they sounded very smooth, they were also very laid back - the high end and midrange were very clear, but the high end was very recessed, which is not the sound that I favor.
I would also throw something out there to anyone thinking of making their own cables. Unless it's changed, HiFiMan used to use those nice little gold plated screw on connectors at the ear cups (I forget what they're officially called). If you want to make your own cables, you can buy the connectors separately from some high end shops for about $20 each. However, if you look around, you'll find that those same connectors are used for WiFi antenna signals.... and can be bought under that description on eBay and elsewhere - for around half that price or a bit less. Note that they are tiny, and are a real nuisance to solder.
Amongst my cans are a pair pf HE-500's. I thought they were the only ones that Hifiman made that came with a stiff microphonic cable made of twisted Teflon insulated silver wire. Silver or copper I don't care, however, the ergonomics suck. I really like the HE-500's, yes I have a strong weight bearing neck.
