Linum SuperBaX G2 MMCX Cable Synopsis

Linum SuperBaX G2 Cable

This Synopsis

When you want the best audio on the go, you still can’t beat a wired connection. And being that many of the best earphones on the market have a removable cable design, the doors are open to third-party audio manufacturers to come up with compelling reasons for you to drop your stock cable. The fact of the matter is, while headphone manufacturers make the stellar sounding earphones that we know and love, that same greatness isn’t necessarily transferred to the cable design. Most times, it can get you by (it has to), but dedicated cable manufacturers often come up with something not just ergonomically superior, but can also release out a bit more of your earphone’s sonic potential.

One cable manufacturer that has garnered some attention due to its ultra thin cable designs is the Danish company estron a/s. Its Linum cables support the several earphone connector standards out there. This synopsis sums up what you can expect from the company’s latest SuperBax Generation 2 (G2) cable with the MMCX connector (that work with Shure, Westone, etc.)

The Rundown

Because of how incredibly thin the original Linum BaX cable was, it had a not so ideal impedance of 1.5 ohm. The SuperBaX was created to cut that spec in half to 0.75 ohm. But it did add an extra strand to do so. The cable is still extremely thin. We paired it with the Shure SE846 earphones, which have a very low 9 ohm impedance. Check out our Shure SE846 Synopsis for more details on this earphone (and its inferior stock cable).

  • Incredibly thin and lightweight (barely feels like there’s anything the ears)
  • Solidly built through-and-through
  • MMCX connectors fit perfectly
  • No noticeable microphonics
  • Silver-plated cooper litz material
  • Different connector options when buying (MMCX, 2-Pin, T2), with 2.5mm Balanced termination option coming in the future.
  • Sounds great


  • Light weight can make the setup earphone-heavy
  • Thinness makes it feel fragile
  • Plastic connectors all around don’t look premium
  • Naturally prone to tangles
  • Not the cheapest third-party cable, at $222
  • No options to customize the looks or connector material when buying

What it’s like to use

The Linum SuperBaX G2 paired with the Shure SE846 and Chord Mojo DAC.


  • The included carrying case is nicely made, but it’s much bigger than it should be for a cable this small.
  • Cable is made of four tightly-wound strands (splits to thinner two-strand winding from the Y-connector to each earpiece), each with its own thin shrink-wrapping.
  • Because the two-strand portion of the cable is so thin, the setup can be heavy at the earpieces (depending the earphone) – just something you have to get used to when handling it.
  • All the connectors (including the chin slider) are all small black plastic pieces. They don’t look so premium, but feel a little better with a soft-touch finish.

  • The MMCX connections are firm and secure (fit the SE846 perfectly) and have a visual blue and red dot for left and right earpieces, respectively.
  • There is no around-ear memory wire. Therefore, when donning the earphones, the cable likes to spring up and out at first (because of how thin it is) but stay in place thereafter. Once it’s on, you barely feel the cable.
  • The cable easily becomes a tangled mess – just the nature of a super thin cable.
  • The chin slider isn’t the firmest, but it functions adequately.
  • Cable is a decent 50″ length.


  • Sound from this cable is very clean and sharp. This makes nice for articulation and separation. Great for analytical listeners.
  • There’s a detectable improvement to airyness versus from the stock cable. This makes the soundstage seem larger. That said, soundstage isn’t the widest.
  • Great tone, balance (no frequency range is elevated), and dynamics.
  • No notable sound quality disadvantage versus the stock cable.

Final Thoughts

Linum SuperBaX Cable
Current Price on Amazon

We’ve ended up very satisfied with Linum’s latest SuperBaX G2 cable. Any gripes we’ve noted are minor for the most part. Some things are unavoidable when you make the thinnest and most comfortable cable. Probably the biggest con is the +$200 price tag. But in the grand scheme of things, this is a mid-range price for a premium cable, which the SuperBaX is. That said, it doesn’t do premium with flair, but with sturdy construction.

We were glad that the ultra thin cable design did not sacrifice sound quality. And this SuperBax version is friendly with sensitive earphones and low output impedance sources. One last great thing is you can finally pick it up on Amazon. For the longest time, the small company only sold it on its website’s online store.

  1. Hi Josh,

    Great review mate. I also have the Shure se846 clear and I also use the yellow tips- so, you’ve got good taste 😊
    Linum have come out with a new more hefty locking cinch. It’s on the T2 and 2 pin connectors, but it’s not available yet for the MMCX Superbax, not till the end of March.
    At first I wanted the smaller cinch, because I never really use it. But now I’m thinking, without the memory wire of the Shure cable, the cinch is a bit more important and maybe I should be using it after all. Do you have problems with the cinch moving around at all? Maybe it’s good for the cinch to be able to move around a bit in case it catches on something?! I don’t know…
    Anyway I’m impatient and want one now, so maybe I should just get the old one because the new one has a bigger cinch that might get in the way more…. audiophile neurosis….
    What do you think?

    1. Hey Will, thanks for the message! So it’s actually good you bring this up. Over time I’ve become less of a fan of the chin slider (which I believe is what you’re referring to as clinch). In my synopsis I touched on that it’s not the firmest but just okay, however, it’s seemed to loosen a bit over time. It now often doesn’t stay in place (unless I’m sitting still, which is like never), and falls towards the Y-splitter. I guess Estron has heard this complaint from many others. Glad to hear they’re improving it, though I wonder why it needed to be twice the size (or more) than the original clinch. It looks a little comical against the thin cable.

      Anyway, it’s a situational call. The chin slider function isn’t a deal breaker for me, just a nice-to-have. I use the cable just fine still. I don’t think there being memory wire or not is a factor. However, I’m not very active with my earphones, and maintaining the wires tidy may be an important factor if you’re mindful of movement.

      I can’t say for sure the consequence of the new size and shape of the clinch. I do like how seamless the original one is. It’s extremely lightweight and streamlined. The flat top of the new design boggles me (is it final?). I see your concern. But just depends what matters more to you – tight function or minimal design.

      Hope this helps! Let me know if any more questions.


      1. That really does help thanks Josh.

        I’m not active with my earphones either. The Shure cable design does catch on my clothing all the time at the Y splitter. I think minimal design matters more to me so I also can’t understand the size and newly designed slider/cinch either- seems bonkers for such a minimal cable. But I guess you don’t know till you try these things. It’s a conundrum for me- “that thing you never used, on your new £230 cable, would you like the old small one that doesn’t get in the way but might not work perfectly, or a new big one that might get in the way but will stick there and not move, oh and for that one- you’ll have to wait 2 months…”
        I’m sure they’re both great, especially since the original Shure cable is a gigantic microphonic monster!
        Cheers Josh,


  2. Hi Josh,

    Update. I now have a Hiby R3 going coaxial into a Chord Mojo with Linum Superbax MMCX into Shure se846. It sounds super super good. Don’t think I’m going to bother with adding a Vorzuge amp for now. It sounds great.
    The old style Linum cinch on my cable is loose, certainly not tight and it very easily slips. I said this to Linum and asked them to send me the new cinch model instead when it’s made at the end of March. They said they actually don’t think the new cinch on the MMCX cable is going to go into production at all because they’re moving away from the MMCX connector and onto T2 which is apparently superior for their needs.
    So this cable with the old style cinch is the only MMCX cable. I’m mega happy with it, it’s a 100 times better than the Shure cable and you’re spot on that the cinch isn’t a deal breaker at all. The Shure’s seem to match the Mojo perfectly too, tonal balance is perfect to my ears.
    Good stuff.


  3. Hey Josh,
    I’m sure you’ve moved on by now but further update. I tried the Vorzuge- made things far too sharp and bright, returned that. The setup with the Mojo sounded great but I’d never listen for much more than 30 minutes and get bored and didn’t really know why. Technically great but, not involving. I wasn’t impressed with the Red but I recently bought a Dragonfly Cobalt and plugged that into the Hiby R3. Now I’m listening for hours and don’t get bored. No big bulk, no major battery drain, no daft Mojo battery to charge, much more relaxing, smooth, more than enough detail, just the right balance with the lows, mids and highs. The Cobalt is really really quiet (noise) and platform agnostic so it works just as well with an iPhone. I sold the Chord got the Cobalt, pocketed the £60 and everything is better all round.
