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

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.

this is a good value for the money. I had ordered one, but it turned out to be too short (my bad) so went back and ordered another one. Was going to return the shorter one but I am sure we will end up using it and it seems good quality so will just keep it

I bought this cable for my Sennheiser HD 600 phones. I like this cable! It is made well and looks great...for a cable. The braided cable material is a nice feature which keeps the cable from getting twisted & tangled. I also like the input plug with the spring which will keep the cable secure from shorting at the plug. This cable is more sturdy and thicker than the more expensive version I was using. Lastly, the length option is a plus. I bought the 2mm which is perfect for the space I work in. I would highly recommend this cable.

The cable seems nice. It has a braided cover. The audio plug has a spring for strain relief and the plug is gold plated. 1/4” Gold plates adaptor included. The Y split look janky but sturdy. The connectors to headphones don’t seem as sturdy as the Sennheiser factory but I have had no issues. No complaints, they work! Sound great, no sound downgrade.

I just got it so I've used it for less than 10 minutes but it plugged in easily and it sounds fine. What a sigh of relief to hear sound out of both earcups reliably without the left side cutting in and out. I've had HD650s for close to 10 years and the original cable (I think? Maybe I replaced it years ago - can't remember but it if so it was an OEM cable) honestly worked fine for me ... until it finally didn't. It was really long and I'd sometimes accidentally roll over it with my office chair's wheels. Well, after doing that enough times it finally starts cutting out on the left earcup. I ordered this cable mainly because it was Prime and would arrive in 2 days. I ordered the 2 meter one and I think its the perfect length for me because it has plenty of slack but its not long enough where it touches the floor and so there's no way I'll run over it. I'll update this review after 6 months of usage or when it stops working. Whichever happens first. Fingers crossed I won't have issues with it. Update: it’s been 6 months and no issues to report. I even had an instance where I accidentally yanked on the cord but it’s all good.

A good quality cable, while it works. Lost audio in the right ear after almost exactly 6 months. I've had my HD6XX's since 2017, and in that time I've gone through three cables: 2 genuine Sennheiser cables, and this cable. Both Sennheiser cables lasted about 4 years, and this NewFantasia cable lasted 0.5 years. With both cables being about $20, I'm going back to the Sennheiser cables.

Very nicely made good quality cable. That said, I have one minor small-detail-change recommendation for the manufacturer> Add a red stripe on the right side cable near the plug (see photo) or, change the right side plug color to red. (see the red stripe in the attached photo which is a added 1/8" wide piece of red electrical tape).

Es un cable de fabricación robusta, se siente resistente, espero que sea durable. Se compró para sustituir el cable original de los Sennheiser HD 650, cuyo cable es muy largo e incomoda para usarlo en el escritorio. Este cable de 1.2 m queda perfecto puesto que mi DAC esta a 60 0 70 cm. En cuanto a la calidad del audio no he hecho las pruebas suficientes pero mi primera impresión es que es muy parecido al original, no puedo notar la diferencia. es una buena opción.

Funcionou perfeitamente, não deixou a desejar em relação ao cabo original. Recomendo!

Really really nice replacement chord for the Sennheiser 600 that I use, just solid quality. Worth the price imo

Les prises fonctionnent à merveille sur mes Sennheiser HD6XX Massdrop!

On time and it works, what more can you say. Well done.
