If you're plugging your HD-600's into an iPhone, you probably won't notice much difference. If you are using your HD-600's with a good headphone amp, then I would expect you to notice a not-subtle improvement. For me, I first upgraded to a good headphone amp (Schiit Lyr) using the stock cable. After listening to that for a few days, I upgraded the cables to these Cardas Cross cables. I was expecting some subtle differences, but what I got wasn't subtle. The improvement was very obvious. I've had cable upgrades that made no noticeable difference before, and had one or two hoped-for upgrades that turned into downgrades, but in this case, the improvement was very obvious. Your mileage may vary depending on the rest of your system, but in my case, these cables were easily worth the price.

These cables sound as good as I remember them. AudioEquip also overnighted these cables within 48 hours, after my stock cables failed.

An absurd price to pay for an article that makes only a marginal difference, if at all.An A/B blind listening test with the stock vs. the Cardas cable will show you that this is so.

Very nice cable, I love the hd6xx I have a decide not to save money and buy the cable, it improves the sounds significantly and looks so good

It's really great handmade stuff and improve sound quality. The cable length is 3m not 2m and made with fiber not silicone as picture shown which is much more soft and good handfeeling.

I have absolutely no complains.Thanks a lot for this cable !

Great upgrade

Must be a broken wire or bad connection because these sound awful
