Yinyoo 6-core Copper Cable Review – An Affordable Upgrade.

Yinyoo 6-core featured2

Cables are an important aspect of every in-ear monitor. If you’re using your earphones every day then the cable can make a big difference to your overall experience.  Some I find rather annoying, like ones with memory wire or ones that are really springy or noisy. In the past, the solutions were often more expensive than the earphones themselves. Well, not anymore. You can get a very easy and inexpensive upgrade with the Yinyoo 6-core Copper Cable.

This cable comes in all the common configurations and you can choose the plug and connectors that suit your needs. And as a bonus, this cable looks and feels fantastic.

This sample was provided for the purpose of an honest review. All observations and opinions here are my own based on my experience with the product.

  • Is tangle resistant
  • It’s strong yet supple and has great aesthetics
  • There’s a wide variety of plugs and connectors available
  • Is very affordable
  • None at this price

Package and Accessories

The cable arrived in a resealable plastic bag, along with a warranty card. That’s really all there is to it! You’ll see later that the value was put into making the cable rather than into superfluous packaging and that is definitely how it should be for a budget product.

Build Quality and Design

Yinyoo 6-core wound

The Yinyoo 6-core copper cable has – you guessed it, 6 cores! Seriously though, there are 3 cores each for the left and right channels. Each core is individually sheathed in a transparent insulation which gives a clear view of the copper wiring inside.

There are several configurations available for this cable. You can choose between MMCX or 0.75mm 2-pin connectors. Then for the plug, you can choose 3.5mm single-ended, 2.5mm balanced or 4.4mm balanced. I chose MMCX and a 4.4mm balanced plug.

What surprised me first of all, was the suppleness of the cable. It’s extremely malleable despite being quite thick below the Y-split. There is no stickiness to it either and it feels as good as it looks. Even now after using it for a week I’m still shocked at the high quality of the build and materials.

There is no memory wire or preformed hooks at the top of the cable, which is the way I like it. I don’t mind preformed hooks but they tend to get tangled at every opportunity. Memory wire, on the other hand, should be condemned as far as I’m concerned! 🙂

The aluminium MMCX connectors are silver in colour. There are a couple of concentric rings engraved into the bottom half that provides a little grip which is useful when detaching the connectors from an IEM. The right side has a red ring around the top end to help identify it and I really like this.

The Y-split is a simple silver-coloured cylinder with Yinyoo branding printed on it. It’s small, lightweight and unobtrusive. Just above the Y-split is a clear plastic chin slider that is a little bit loose but otherwise works well, unless you’re moving around a lot.

Finally, the cable terminates in a straight aluminium plug. Overall the build quality is superb for the price.

Comfort and Microphonics (cable noise)

In terms of comfort, the Yinyoo 6-core is fantastic. Compared to many other cables that I have (including some from rather expensive earphones) this one is just delightful to use. It sits perfectly thanks to its suppleness and it’s very lightweight despite its significant girth.

Because there is no memory wire or preformed hooks the cable works perfectly worn over-ear or cable-down, making it extremely versatile and compatible with any IEM.

Its minimal microphonics is also excellent. There is very little cable noise, especially when wearing it over-ear style.

For testing, I used the cable with my Sony NW-ZX300 balanced output and several IEMs including the Whizzer A15, LZ A5 and Tin Audio T2.

For the most part, I did not hear any noticeable changes in sound when using this cable. I believe with budget cables like this you are paying mostly for visual and ergonomic upgrades rather than audible ones.

I will say, however, that there seemed to be a little extra body and smoothness with the T2 compared to its stock cable.

Yinyoo 6-core Copper Cable Conclusion

Just when you think you can no longer be surprised at the incredible value of Chi-Fi, something like the Yinyoo 6-core copper cable comes along. It’s very well-build, comfortable, aesthetically pleasing and it’s available in just about any configuration you can imagine.

If you’re looking for a replacement or an upgrade for your current IEM cable, this is an excellent option and I would absolutely recommend it. At the regular price, it’s a great deal but at the special discounted price it’s an absolute steal.
