Great wire. It sounds perfect and has held up with daily use for I don't know how long at this point. The included 1/4 inch jack is a nice bonus

Sound quality is true original cables; overall built quality is very resilient and clutter free.

Sounds great, even better than the original cable! And it eliminated the humming from my little dot Mk2, great cable for a good price!The cable is sturdy and it have hard plastic mesh protecting the cable. High quality.10/10 and happy with my purchase.

I accidentally broke my original wire. I bought this product and I love it. This one is way better than original wire.

Basically I liked almost everything about this product. It worked absolutely fine with my Sennheiser HD 600's, and I hear no difference in sound from the original Sennheiser cord. I was also very impressed by the thought that went into the NewFantasia cable. They seem to have taken into consideration the places at which cables eventually break.If my following description isn't clear, please refer to the picture for this item.ONE is at the connection to the 3.5 mm jack. First of all, the jack itself is metal and not molded plastic. Behind the jack is a spring jacket to help relieve strain on a typical breaking point in the cord. TWO is the non-twist covering for the wires leading from the jack to the point where the cord splits in two to go to the right and left headphones. It is made of some kind of braided material. I don't know what it's made of, but it looks and feels a lot more durable than the original Sennheiser plastic cable. THE THIRD is at that bifurcation point, which is covered in a metal casing.My only regret is that they didn't do a little extra at the last usual breaking point, which is where the ends of the cord connect into the headphone itself. Maybe if they devised something akin to that spring-jacket thing they did back down at the headphone jack, that would have been a masterstroke.Truly, I've only had this cable for a day, so its actual durability is a question I really can't answer, but, like I said, it LOOKS like it's purposely been built to stand the test of time.One reviewer mentions that the cord ends are not color-coded. That is true, but each one is stamped "L" or "R".I must also say that this cable is only about half the length of the Sennheiser cable.That made absolutely no difference to me for my use, but if some of you want to plug your headphones in and sit across the room from your system, you might have a problem.All in all, I highly recommend this product.
