NewFantasia Replacement Audio Upgrade Cable Compatible with Sennheiser HD650, HD600, HD580, HD58X, HD660S, HD660S2, Massdrop HD6XX Headphones 3meters/9.9feet

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.

A little stiff but durable and good. Comes with 6.35 adapter!

It pains me to read reviews from those who have had a bad experience and so I'd like to share my experience with this brand of cable. First off, this is my second New Fantasia cable and I have not had an issue with either cable. See, I purchased the first one a couple of years back to use at my desktop system. I don't wear my HD 600 headphones outside or take them on the go. I bought the shorter cable because the OEM cable was just way too long. When my cable arrived I did in fact find it to be a very snug fit and had to do a bit of fussing with it. I have never had an issue with performance as it is well constructed. Sound wise I haven't noticed it any better or worse than the OEM cable. I recently purchased a tube amplifier to use at my desktop and as my system has changed a bit I found that I needed to purchase a cable which was a bit longer in order to make it to the jack on the tube amplifier. It reached, but once I sis back in my chair it will tug on the amplifier. OK, so I got the cable this morning and I too struggled to to pull that first NewFantasia cable out and had to grab a pair of pliers. I gripped the ends of the cable firmly but gently enough and them gave a slight tug while carefully kind of rocking them side to side and both ends came out fully intact. Nothing damaged at all, and the best news is that once I pushed the new cable into each ear cup it went right in and is now much easier to pull out by finger yet secure enough to never fall out. All in all these are very nice yet inexpensive cables to have if you aren't one who buys into the idea of cables being inherently better based on price. Just don't be like a bull moose in a china closet!

I purchased this cable in March of 2024. Now I'm noticing the sound cutting out on the right side. The cable has lasted me about 22 months. The longevity is more or less comparable to the original Sennheiser cables, which also seem to last 2 to 3 years - an unforgivably short lifespan. Unfortunately, I can't give a good review to any wires that die this quickly. I've seen EKG wires last a decade in a military ambulance - so I know for sure that we have the technology to manufacture cables that aren't garbage. One would think cost is the problem, after all a set of EKG leads can cost around $200 - but that's for a complete set of 10-12 wires. If we pro-rate that, we should be able to achieve the same quality for around $40 in headphone wires. Performing identical to the 2 sets of original Sennheiser cables I've owned, the problem always happens near the headset connector - that's always where the wire fails. Unfortunately neither Sennheiser nor NewFantasia has managed to solve this quality issue. My search continues for something that DOESN'T die in less than 3 years. Sound quality is of course perfect - wires will never affect your sound quality unless they're astonishingly poor quality or hundreds of feet long - so this cable sounds just as fantastic as the original OEM item.

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.
