Epsilon MKIII – cable de mejora para IEM y auriculares de cobre UPOCC Litz

I bought it for my Symphonium Titan to replace the stock IEM cable and the results are really good. I have placed my second order for my Dunu Da Vinci.

Got this cable for my 64Audio U4s, as flat 2-pin cables are not very common (most companies only ship cables with standard recessed 2-pin connectors, which look funky when paired with 64Audio's protruding socket assembly). The cable itself is relatively well-built, although the injection-molded plastic around the y-split does have some bit of fraying, and the plug does have a small, shallow dent. The wires itself are pliable, soft, and don't tangle. The ear hook itself is quite thick, but still comfortable. The fit and feel of this cable is significantly better than 64Audio's stock cables, which actually cost more (retail).

Sound wise, the U4s is definitely better than 64Audio's stock "Premium" cable (SPC material). It has a slightly poofier bass response, with more meat, but less control. The mids are relatively the same. And the treble is slightly more laid back, in that it kills some of the brightness/harshness the U4s, and many other tia-equipped 64Audio UIEMs I've heard. In general, it makes the U4s more palatable for my tastes.

The most surprising thing is that this sub-200 USD cable ships with a personalized card that has the owner's name hand-signed upon and a grey leather case, something lots of other boutique cable companies fail to do, especially with their entry-level products.

The cable connection is significantly better than factory original, and it rests comfortably around ears. Most importantly, my IE600 now sounds amazing.

Both the build quality and sound quality of the product are excellent. It upgrades the ie900 without compromising its character. It is lightweight and suitable for outdoor use. Highly recommended.

I purchased this cable to replace stock IE600 cable. It is a cable with better built quality compared to the stock one. Sound clarity improve by a bit.

Love the weight and thickness of the cable. Improved the sound quality as well—fantastic customer service, responsive and accommodating.
Area to improve - punch. Too small. Can't fit my IEM.

Great quality upgrade to my stock cables, feels and look great, and incredibly quick shipping!

I've been using this cable for over a month and I'm happy with my purchase

Compared to stock cable of Z06, the 8-wire version of Epsilon gives a good upgrade while not changing the original sound signature.

I have cables that cost several hundreds of dollars and they pale in comparison to this. It is incredibly well made. Shipping was fast, too.

Null Audio is going to be one of my go-to cable manufacturers going forward.

Great looks, top quality and most importantly a noticeable improvement in sound quality.

My favorite cable ever. Nice and lightweight, and built super well. Highly recommended!

I thought that my ThieAudio Monarch MkII IEMs deserved something better than the somewhat microphonic stock cable. As I had already benn delighted by my purchase of a Brevity for my Sennheiser IE600s, I plunged for the higher spec Epsilon. Good decision. Warm, enveloping sound with great comfort and ease of use.

I love these cables. This one is slightly warmer than my last Ethos which is what I was looking for. Really nice build and it is in black which is what I wanted.

The cable looks and feels amazing. Customer service for a custom length was also a very pleasant experience. Bought it for my IE900 the connectors fit perfectly. I can only recommend this !

Bought it for my IE900. Best cable ever used so far. Building quility is super solid. Very premium looking with the new designing. Sound is fantastic. Definitlity will recommand to others.

I bought the Epsilon Series Premium Upgrade Cable for my Hifiman Aryas. The packaging and cable is top notch. The only issue is how they fit, leaving a 1cm gap between the connector piece and the headphone. This doesn't seem to affect sound, but it is a little strange and unexpected.

Null Audio won't fail you.

Hello, first of all, thank you very much for your work! All redy IEM Sennheiser IE900 it's amazing IEM and now with your cable, every thing i'ts fabulous! Thank you again. I will buy a Epsilon balanced 4.4mm for IE900 soon.

This is by far the best upgrade cable for the IE600, the fit, size and sound quality are perfect.

I was on the fence of returning the IE600 due to its absolutely lackluster performance from the headphone cable. No product should be that faulty. My friend convinced me to give them another go but to buy a null audio cable. Not only is the connection now solid and dependable, but the sound signature is everything I was expecting when I bought them in the first place. Cable construction is better than anything I have purchased, they are comfortable, high quality, and really fantastic across the board. Any more high end IEMs I buy, the first place I'm next is to build a cable through this website. 100% worth it!

Great cable. No microphonics or memory and sound stage is wider too.

It bring warm to my IE600 especially for jazz music.

Build quality top notch.

Purchased this cable with a USB-C DAC (ESS9280) and the cable has clicks and pops when using with usb-c devices. Seems to be defective, looking to get a replacement but support has been slow to respond and resolve the issue.

Awesome!
