I have a long history with HanSound Audio and have been a fan of their upgrade cables for a long time. So when the HanSound Fuxi 8-wire and 4-wire showed up on my doorstep, I knew I was in for a treat. The Fuxi comes in at around $150 for the 4-wire and $240–$280 for the 8-wire, depending on connector and termination material.

HanSound Audio got its start in spring 2012, bringing high-end acoustic design principles into the world of earphone cables to cut down signal distortion and bring out more detail in the music. Rather than buying standard cable structures off the shelf like most brands, they design every cable in-house and have it hand-built by their own trained staff at approved Taiwanese factories, which is a big part of why their cables sound the way they do.

Design

HanSound has been making cables for a long time, and it shows. Both the 8-wire and 4-wire versions have tight, uniform braids with none of the loose or uneven spots you sometimes see on budget cables. It’s not a flashy design, but it’s a confident one.

They don’t list a wire gauge anywhere, but holding it side by side with my well-worn Kimera, the Fuxi is clearly cut from the same thicker, sturdier cloth rather than anything thin and delicate. Internally, it uses two different conductor sizes twisted together for better signal efficiency and less transmission loss.

The hardware is matte black aluminum alloy across the board, except for the chin slider, which breaks things up with a warm copper tone. HanSound’s logo shows up twice: printed on the plug, etched into the Y-splitter. A subtle red ring on the right connector marks your channel, and honestly, I’ll take that over the tiny L/R engravings that are nearly impossible to read in dim light. For a cable at this price, that’s a lot of thoughtful detail. I gravitate toward the 8-wire for the extra girth (less tangle-prone, and it just feels better bunched in the hand), but the 4-wire holds its own if you want something lighter and more discreet.

The ear guides are soft and pliable rather than stiff, so they sit comfortably without fighting your ear. Microphonics are basically a non-issue. I shifted around, walked, and brushed it against my shirt, and never picked up the thumping or scratching some cables transmit straight to your ears.

Sound

Let’s get the obvious out of the way first: Fuxi is a warm, body-forward cable. You notice it almost immediately. Bass gets a lift in weight, not just a boost in quantity but actual impact behind each note. On Sleep Token’s “The Offering“, kick drums land with more authority and texture, and this bass behavior sets the tone for the whole presentation, though it’s more nuanced than that.

Mids follow the same trend. Vocals move a touch closer and feel more grounded, less like they’re floating in front of the mix and more like they’re planted in it. If you’ve got an IEM that’s technically excellent but leans a bit clinical or thin, Fuxi is the kind of cable that addresses that without you having to think too hard about why it works.

Treble surprised me a little, honestly. Copper cables have a reputation for rolling things off up top, and I went in expecting some loss of air. That’s not really what happens here. There’s a light smoothing at the very top, sure, but detail retrieval doesn’t take a real hit. Porcupine Tree’s “Trains” still has plenty of shimmer and decay in the cymbals, it’s just presented a bit more politely than it would be through a more neutral cable.

Soundstage is where Fuxi shows its hand a bit. It’s not going for width. Compared to the Hansound Nüwa, the stage pulls in and gets denser rather than wider, everything feels closer together and a little more three-dimensional as a result. Some people will miss the extra air, but I actually think this suits a lot of the IEMs people are likely to pair it with. It’s not chasing scale, it’s chasing solidity.

4-Wire vs. 8-Wire

Both versions share the same basic tuning, so don’t expect the 8-wire to sound like a different cable entirely. What changes is how much authority is behind everything. Bass tightens up and gains more weight on the 8-wire, and instruments generally feel a bit more locked in place within the stage rather than sitting slightly looser.

The 4-wire isn’t lacking, though. It’s the lighter, easier-going version of the same idea, and honestly gets you most of what makes Fuxi what it is. If your IEM is already fairly resolving and you just want a touch more body, 4-wire probably does the job fine.

Where the 8-wire earns its price gap is with higher-end gear. On something like [IEM], the extra density stops feeling like a tonal tweak and starts feeling like a genuine step up, more like an upgrade cable in the traditional sense rather than just a flavor change. Then, of course, is the purely physical aspects: I prefer the weight and thickness of the 8-wire, as well as how it handles and drapes. It’s great to have options!

Verdict

At $158 for the 4-wire (or $249 for 8-wire), the Fuxi undercuts what a lot of brands charge for comparable build and materials, and it doesn’t sound like a budget pick either. That warm, textured copper sound paired with hardware and handling this solid is honestly a bit of a steal. If you’re after an affordable upgrade cable that doesn’t sacrifice on either front, Fuxi earns an easy recommendation.
