NewFantasia Replacement Audio Upgrade Cable Compatible with Sennheiser HD650, HD600, HD580, HD58X, HD660S, HD660S2, Massdrop HD6XX Headphones 1.2meters/4feet

Feels nicer than the original cable and its a better length.

Works great for my HD600's. Shorter than the originals, but I think the reason my left side was going out on originals was because I tripped over the super long cable a bunch of times yanking them off my desk. This cable seems sturdy, and less likely to get tangled up in my feet since it doesn't reach the ground anymore.

I was skeptical about this item at first , but the wire for my HD660s broke . I bought myself this replacement and it’s way better looking than the original and also shorter (the oem would get tangled) . sounds the same so you don’t lose any decibels .

I bought these to replace the stock cables after they started cutting in and out, purchased in June 2022. (For HD 650's that were at least 6 years old, probably older.) The cable length is perfect for my setup and feels very high quality. Sadly, after three years of use (some of it admittedly rough,) they've started cutting out at certain angles. I was glad to find them in my order history and that they're still in production, because I'm ordering another set. 3 years ain't too bad, and I think more careful use would've let them last longer.

I was skeptical with it not being Sennheiser’s brand, but was left very surprised. Exact same sound quality with my 660s original cable. It even snaps right in, better than the original cable. Absolutely no complaints with a very good price.

Perfect replacement for a Sennheiser HD600. It is also only a meter which works much better for carrying around a portable player. the three meter cable gets stepped on and tripped over a lot. Which is probably why I needed a replacement...

Build quality is decent as always from NewFantasia. I have been using them for my headphone re-cabling needs for a few years now and have always been very happy with their cables.The nylon sleeving keeps the cable stiff and tangle-free while still allowing full flexibility. It has the potential for microphonics against clothing among other things if you use these as mobile cables. That said it works fine for a desktop headphone amp. The 3.5mm TRS connector is beefy with great stress relief and the Sennheiser L/R connectors are as stout as they need to be. The screw-on 1/4" adapter is decently made and fits flush on the connector. This cable is plenty heavy-duty for home use with an amp.Have seen several reports of the connectors "being too soft" and bending or deforming when they are inserted. If you have to use enough insertion force to actually damage the cable, you are inserting it wrong, period. These insert easily into my HD580s and snap in and out crisply but need nowhere near enough force to damage anything. Maybe stop for a second and look at what you're doing before forcing a $400 pair of headphones to the point of damage? Just a thought.No perceptible difference in sound quality over the HD650 cable with my HD580. The 5 foot length is my main draw here as I find anything shorter way too short for my desktop amp and anything longer to be a nuisance. It's a rare length and NewFantasia makes pretty much all of their cables available in 5ft lengths. Being that they're otherwise very nice cables, that makes them a real must-buy for me. If there's an audible difference between cables at this short distance it usually means there's something wrong with one of the cables. At this level you shouldn't expect a difference. I bought this cable for functionality alone. Many report there being a clear difference between the HD600 and HD650 cables. I believe that's because some HD600 cables have an inadequacy somewhere. Either channel imbalance or an impedance issue or something. Sennheiser do not "tune" their cables. I have used many different cables in my time and have never heard a difference unless one cable had an issue. It's just copper passing electricity. Maybe some of the incredibly priced audiophile cables make a slightly noticeable difference, but nothing can really claim to be an outright improvement.This cables performs the expected function quite well. It looks good, is practical, and is decently built. Can't ask much more for the price.

I purchased this item at the end of September 2023. Barely three months later, I need to replace it. It suddenly developed a short in one of the cables near the headphones, as they all do.There were three major problems with this cable.1: By far the biggest issue is how short the separated portion of the cable is. By that I mean the left/right cables that go to the speakers after the Y split. They're not quite a foot long. This contributed greatly to their demise, because the closeness of the Y split meant that the left/right cables were CONSTANTLY touching my neck. Designs with longer lengths after the Y permit the cables to remain separated and avoid brushing up against the neck, and in turn avoid the kind of wear and tear that leads to fraying.2: The Y split is a design that defeats any thought of extending the split to fix problem #1. The rest of the cable below the Y is a single wire that cannot be split further, unlike other HD650 replacement cable designs.3: When it developed a short, that was it. Notwithstanding my CONSIDERABLE effort, I could not position the wire at a fixed angle and tape it in place to regain temporary sound from both speakers. The wire was too frayed to allow this. THIS TELLS ME THAT THE ACTUAL WIRE INSIDE THE BLACK RUBBER IS EXTREMELY THIN, WHICH OBVIOUSLY OPENS THIS CABLE TO EXACTLY THE PROBLEM I ENCOUNTERED IN JUST THREE MONTHS. Was it really worth saving a couple of pennies on some copper?Easily the worst replacement cable I've bought.
