Review: Linum SuperBaX – Switzerland

Linum SuperBaX

Today we’re looking at the SuperBaX cable by Linum, a light and high performing aftermarket cable.

About Linum:

If you have ever considered buying an aftermarket cable, you definitely came across Linum. The Danish earphone cable brand has been around for a few years already and has brought us many great cables in the past.

Lieven has done a good number of reviews for Linum cables already, a list of relevant links can be found at the end of this article.

Linum is owned by Estron, a company that has been working in the hearing aid and audio business for some years now. They’re one of the biggest suppliers when it comes to hearing aid wires. When keeping this in mind, it makes a lot of sense that comfort is one of their top priorities.

In Linum’s portfolio we can find three different cables. The Music, the BaX and the SuperBaX. The SuperBaX has been in the works for quite some time and Lieven has looked at their prototype all the way back in 2016. Today, I will take it for a spin and give you my evaluation.

Last year (2018) Ultimate Ears announced that they will bundle their UE Live monitor with the SuperBaX cable of Linum. Partnering with what might be the biggest player in the pro-audio CIEM filed is more than just good recognition for Linum, it shows how much the industry values their quality.

About SuperBaX:

The SuperBaX is a four wire IEM cable that delivers the ultimo of comfort. It is very lightweight, flexible and still perfectly built. It is made of 168 silver plated copper Litz strands and has an impedance of just 0.75 Ohms.

For cables the impedance is a very important factor, and you want it to be as low as possible, to not hold any of the signal back. SuperBaX can be ordered with MMCX, 2-pin or T2. All their cables are sold with a right angled 3.5mm stereo plug. However, I did request a 2.5mm balanced termination and also got it. So I guess you just have to ask.

SuperBaX can be acquired directly from Linum for about 249€ (incl. VAT) or from one of their many partners world wide.


Linum ships their cables in nothing more than just a small plastic bag together with a silicone cable binder and a short user manual. That’s it. On one hand, knowing what their competition offers, I feel they could give a little more accessories, but on the other I don’t think anything’s missing. You’ll hook the cable up to your monitors, and there’s no need for more to be honest. Especially at that price.

Build Quality:

Prior to this review I have only handled a Linum cable once in my life. It was 2016 at a headphone show in Germany when I came across the booth of Headphone Company, their regional distributor. The people running the tables were incredibly nice and I am still sometimes in touch with them just talking audio.

I was really impressed by the extreme comfort and tangle-free effect of the Linum cables they had at the show. However, I must admit, I didn’t try one out then. Why, I don’t know to be honest. Fast forward to late 2018. Linum has sent me their SuperBaX and trying it out I did.

From the build quality perspective, I think the SuperBaX is a very nice product. The braiding is excellent and consistent, it’s straight and indeed pretty much tangle free. It also is the most comfortable IEM cable I have tried to date. In the past I’ve always been raving about PlusSound’s single wire X series cables. While they’re still top comfort, the Linum beats it. Once you have the cable around your ear, you’ll forget it’s even there.

My cable is terminated to a 2.5mm balanced plug. This one is made of metal and probably the heaviest part of the entire cable. It still isn’t anywhere near heavy though. One thing I like about the SuperBaX a lot is the implemented chin slider. It has a simple, yet well working locking mechanism which keeps the cable in place.

At the very top end of the SuperBaX there are the 2-pin connectors. These are the smallest ones I’ve seen during my entire time in audio. While they’re excellently labeled with a red and blue dot for right and left, they also don’t look like they’re suitable for recessed sockets. Rendering some of my monitors unable to play with the Linum. Also worth noting is, that the cable does not provide any preformed earhook and no memory wire (thankfully). This makes it perfectly capable of being used with glasses.

A daytime code monkey with a passion for audio and his kids, Linus tends to look at gear with a technical approach, trying to understand why certain things sound the way they do. When there is no music around, Linus goes the extra mile and annoys the hell out of his colleagues with low level beatboxing.

      I’ve read a lot of good things about Linum, regular BaX is definetly on my to-buy-ASAP list.
      Could you get Linum Music and regular BaX for a review for budget-minded audiophiles?

      That’s the Noble Khan in the last photo? Also pardon me on this, but why would you not use the SuperBAX on EE IEMs? I don’t fully get what you mean re. the semi-recessed connector. Many thanks.

        Hi Phil,
        thanks for your comment.

        Well spotted! Yes that’s the Khan. I wanted to sneak it in. You’ll be seeing more of it in future reviews and of course in the full length feature in a few weeks.

        The reason why it doesn’t work well with the Empire IEMs is that the 2pins of the SuperBaX are too small body wise. They do fit in, but it’s more difficult to grab and to get them out again… the universal IEMs of EE have flushed sockets, so there wouldn’t be that issue. It’s only the CIEMs.
