I recently came across a few forum posts about a company out of Denmark making high-quality MMCX replacement cables for in-ear monitors. On their website the “Linum by Estron” brand claims their earphone cables are the “thinnest and lightest cables for IEM’s and earphones”. I’ve got a set of the new Linum (generation 2) Music, BaX and SuperBaX MMCX cables and I’m going to give them a full review with some Westone and Shure IEM’s to see if they’re worth the money.
Linum G2 Music MMCX Cable
About Linum G2 Music MMCX
The Linum G2 Music MMCX cable is designed for all-around, on-stage and in the studio recording applications. According to the specs, the Linum Music MMCX keeps impedance low at 2 Ohms and keeps the bass punchy while sustaining clarity in the mids and high frequencies.
Contents and Design
The Linum G2 Music MMCX cable itself feels nice. It’s an extremely thin cable but believe me when I say it feels a lot stronger than it first looks. And plugging it into my test IEM’s I found the plugs on the Linum G2 Music to have a more solid snap. The L-shaped 3.5mm connector is the only way to go for a cable these because it reduces the chance of damaging the socket of the source device. The case for the Linum G2 Music MMCX is sold separately but it’s definitely a high quality case and worth the money. So far I like this MMCX cable.
Sound
I tested the Linum G2 Music MMCX cable with a Westone W10 and a Shure SE315. In both instances I could actually hear the difference in clarity and all-around frequency response. Using the Westone W10 the Linum G2 Music MMCX cable was incredibly responsive. The relatively flat sound signature of the Westone revealed noticeable definition and reduction in noise. And when testing the Shure SE315 I got the same result. The punchier sound signature of the SE315 remained the same but the clarity and definition increased compared to the stock Shure IEM cable. Later on I went back to the G2 Music MMCX and tried it with a Westone UM20 to see how it would be with a flat frequency response. Again the Linum G2 Music was better and added increased clarity and separation over the stock cable.
Linum G2 BaX MMCX Cable
About Linum G2 BaX MMCX
The Linum G2 BaX MMCX cable boasts a very low impedance of only 1.5 Ohms and features a slightly different design. The Linum G2 BaX has a twisted pair of cables leading up to the splitter. From the splitter, the Linum G2 BaX has the same thin yet durable cables leading up to the MMCX connections. The Linum BaX is designed to be used for high-end audio listening and claims even more separation between the lows, mids and high frequencies.

Just like the Linum Music, the Linum G2 BaX MMCX cable connection snapped into place very nicely. The way the Linum MMCX cables drape over the ears is similar to the Westone which I prefer over the Shure memory wire. It provides a perfect fit every time and gives the same protection from slight tugging on the wire. The carry case for the Linum BaX is also sold separately.
Sound
I tested the Linum G2 BaX MMCX cable with the Westone W40 and Shure SE535. These mid-priced IEM’s perform quite well on their own and feature added clarity and overall sound quality. Using the Linum G2 BaX I found the claims of reduced crosstalk and increased sound quality to be very accurate.
Linum G2 SuperBaX MMCX Cable
About Linum G2 SuperBaX
The Linum G2 SuperBaX MMCX Cable is the ultimate premium cable of the entire Linum line and features and ultra low impedance at .75 Ohms. The Linum SuperBaX is designed to have the best sound signature possible for high-quality music listeners.
Contents and Design
The Linum G2 SuperBaX MMCX is the strongest of all their IEM cables with a quad-twisted wire. This cable can supposedly withstand the force of up to 26 pounds without breaking. Quite impressive. Unlike the other Linum MMCX calbes the SuperBax includes the sturdy carrying case and it also has a nice magnetic strap to keep your wire together when stored. The storage case has several pockets inside for your IEM and other accessories.
Sound
I sampled the Linum G2 SuperBaX with several earphones to see just how diverse it is. First I tried the G2 SuperBaX MMCX with a Westone W50. Just like the other Linum cables the difference between the sound of the SuperBaX cable was very noticeable. From the bass to the very top frequencies I found the SuperBaX increased the separation and clarity of my music. In addition, the SPL seemed a bit stronger with the crosstalk interference out of the way. Very nice. I also sampled the G2 SuperBaX with a Westone W10 and got equal results. Next I tried it with a Shure SE535. Not only do I like the design of the Linum SuperBaX cable much better, the sound quality was majorly improved.

Final Review
Considering I only recently heard about the  Estron Linum (Generation 2) line of MMCX cables I’m truly shocked at how good they are. From top to bottom the Linum G2 MMCX cables lived up to the claims of low impedance, increased clarity and quality build. I’m very impressed with this brand and will be keeping my eye out for other new products in the future by Linum. If you’re a true audiophile with a nice IEM in need of a quality MMCX cable I highly recommend seeking out the G2 Linum line of MMCX cables. They’re well made and they totally improve the sound of your in-ear headphone.
