## Description

Replacement Audio upgrade Cable For Sennheiser HD650, HD600, HD580, HD660S, Massdrop HD6XX headphones Extension Cords

Review: Another Quality Cable from NewFantasia - 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.
Review: A Great Cable! - 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.

## 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.
