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. Review: Read carefully, please. Recommended! - 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! ## Features - Replacement Audio upgrade Cable Compatible with Sennheiser HD650, HD600, HD580, HD58X, HD660S, HD660S2, Massdrop HD6XX headphones Extension Cords - its Cable Diameter is 4mm（After the bifurcation 3mm),its cable material is made with the OFC wire inside & made with the Braided Tangle-Free cable outside. - length:120cm/4ft, package include:1*replacement cable(the headphone is not included) - Its jack is 3.5mm Male & 6.35mm adapter to the jack fit HD650 HD600 HD580 Headphones - It is Compatible with Sennheiser HD650, HD600, HD580, HD58X, HD660S, HD660S2, Massdrop HD6XX headphones ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D76YYKA | | Best Sellers Rank | #84 in Stereo Jack Cables | | Brand | NewFantasia | | Brand Name | NewFantasia | | Cable Type | AUX | | Color | the same as our picture show | | Compatible Devices | Headphone | | Compatible Phone Models | No Compatible Phone Models | | Connectivity Technology | Auxiliary | | Connector Gender | Male-to-Female | | Connector Type | Auxiliary | | Customer Package Type | sealed anti-static bag | | Customer Reviews | 4.3 out of 5 stars 1,340 Reviews | | Ethernet Cable Category | Cat 5 | | Included Components | cable | | Indoor Outdoor Usage | Indoor | | Item Length | 120 centimeters | | Item Shape | Round | | Item Weight | 9.07 g | | Manufacturer | NewFantasia | | Model | 600-SJ-H-120 | | Model Name | 600-SJ-H-120 | | Number of Items | 1 | | Number of Pins | 1 | | Other Special Features of the Product | Braided, Tangle Free | | Outer Material | braided | | Part Number | 600-SJ-H-120 | | Recommended Uses For Product | Audio component for headphones | | Special Feature | Braided, Tangle Free | | UPC | 606184964949 | | Unit Count | 1 Count | ## Product Details - **Brand:** NewFantasia - **Cable Type:** AUX - **Compatible Devices:** Headphone - **Connector Type:** Auxiliary - **Special Feature:** Braided, Tangle Free ## Images ![Replacement Audio Upgrade Cable Compatible with Sennheiser HD650, HD600, HD580, HD58X, HD660S, HD660S2, Massdrop HD6XX Headphones 1.2meters/4feet - Image 1](https://m.media-amazon.com/images/I/71JQFFTHQmL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: The cord isn’t playing sound through right side. How can we get it replaced under warranty?** A: Before replacing it, make sure it's the cord and not the device. Unplug the cord and switch the left and right inputs (plug the right cable into the left headphone and the left into the right). If you're not getting sound through the left side, the problem is the cable. If, however, the right side is still not working, unplug the cable and make sure the device input is not dirty. Blow into it or use a can of compressed air. If this doesn't work, the problem may be with your device. NOW, to answer your question, as with anything, contact the manufacturer. I don't know their return policy. **Q: Are these compatible with hd58x x jubliee** A: The product description says it does. I have the 565s and they fit. It's a quality cable, much better than the surprisingly cheap original. I expected more from Sennheiser. **Q: Are these compatible with the HD 525's?** A: yes,it can work with the HD 525's **Q: Are these compatible with the HD 525's?** A: There is a listing of what they are compatible with as I screwed up my first order. Mine were compatible w/Senneheiser 580's. So I had purchased 2 cords and I don't know which one you are looking at. They ar VERY Short. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Another Quality Cable from NewFantasia *by J***I on March 30, 2018* Build quality is decent as always from NewFantasia.

Right length for me, amazing price. Exactly as advertised. Sounds just as good as the original. The cable doesn't make a big difference unless you're dealing with very high end equipment (which I am not). This is a review after using for 5 minutes. I'll update if anything changes, looking forward to at least a year of great listening (posted in Sep 2026, we'll see when I return - Hope I don't see you here for a long while =) ## Frequently Bought Together - NewFantasia Replacement Audio Upgrade Cable Compatible with Sennheiser HD650, HD600, HD580, HD58X, HD660S, HD660S2, Massdrop HD6XX Headphones 1.2meters/4feet - WC Freeze HD6XX - Cooling Gel Earpads for Sennheiser HD6XX, HD58X, HD600, HD650, HD660S, HD660S2, HD580, HD565 & More, Made by Wicked Cushions | Extra Comfortable and Cool | Black - Sennheiser Consumer Audio HD 660S2 - Wired Audiophile Stereo Headphones with Deep Sub Bass, Optimized Surround, Transducer Airflow, Vented Magnet System and Voice Coil – Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/29531337-replacement-audio-upgrade-cable-compatible-with-sennheiser-hd650-hd600-hd580](https://www.desertcart.com.br/products/29531337-replacement-audio-upgrade-cable-compatible-with-sennheiser-hd650-hd600-hd580) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-24*
