Youkamoo 4.4mm Balanced Audio Upgrade Cable 6ft/1.8m Compatible with Sennheiser HD600 HD650 HD660S HD660S2 HD580 HD58X HD6XX Headphones Silver Plated Braided

Solid value. So nice I bought it twice (thanks to my fat fingers). Out of the box they added greater bass to my Sennheisers, still burning in. =P Worth it.

An excellent upgrade option over the original Sennheiser HD650 cable. When balanced, the audible improvement through a quality DAC dongle is very noticeable, and it's worth it. The terminations are good, and the connectors appear firm, robust, and of good quality.

The cable works fine. I can't say I noticed any improvement in sound quality in my HD6XX headphones but at least did not have to spend a fortune to learn that. I was expecting more of a power bump by using the balanced output from my Fiio K7 DAC/amp - it is there but not dramatic. The cable might be more useful with a less powerful amp. As it is, I still use it and it is a reasonably priced cable to have around as a spare.

This is a perfect quality-of-life (and feature) upgrade for the HD 6XX/650. A much better feeling cable than the OEM, with additional versatility in its ability to connect to balanced outputs. Lives on my 6XX now; when I want to listen single-ended I just use an adatper rather than going back to the pretty awful OEM.

I bought this to get more power into my Sennheiser HD 650 via my questyle M15 dongle's balanced output. IT made a huge difference in the soundstage and details I can hear now with the sennheiser, and a much lighter cable than the stock one. I don't notice any change in sound quality (not a real audiophile, just a music lover). NOw I can enjoy my headphones on the go with just a dongle

Purchase these for my Sennheiser HD 6xx headphones & Hiby R4. They do the job....but they're just basic quality. I've only had them for a few weeks and I can already tell they're not going to last very long... let's see how long. I Will update this review.

This is a really great cable.No microphonics. The assembled cable is quite flexible. The jack is high quality. The looks are really good. Left side is left side and right side is right side.You can't ask for more.

There's no strain relief on the connectors, and the wires broke after two months of normal use. The left headphone only plays audio if I jiggle the cord just right.

Materiales de muy buena calidad. Funciona perfectamente con mis Sennheiser HD58X. En muy notoria la diferencia de calidad en sonido, comparado con los 3.5mm. la experiencia mejora mucho. Definitivamente, conviene el upgrade.

Good for the price

As the title says, I think this is a great product for the price. It came well packaged inside a cardboard box and even bubble wrapped. The cable is 6 feet long, 8 braided conductors (I can't confirm how many strands are in each) then splitting into 4 per side through the alloy splitter and chin adjuster going to the headphone connector. A couple areas where I think they can improve is with the ear cup connector. The connector itself took a like more effort to plug in, they should incorporate some strain relief where the able enters the connector and if they could highlight L or R on the connector to make it easier to identify from a glance as it's transparent. One additional point is the length from the splitter if they can make them equal as can be seen from the photo the right side is a little shorter and you can see the excess on the left side. Overall a great product for what you are getting. I would recommend this purchase to my friends.

Didnt think it was that good but the quality for the price is nice, you get a bag for the cables and a Leatherclamp to hold the cables together, very nice. No production failures. Just a good Cable that fits also on older Sennheiser Headphones like the HD 540 and HD 535. Cant say anything against it. Solid built
