My first impression of the Epsilon Mk II was simply how clean it sounds! It manages to deliver heavy note weight without sacrificing a single bit of speed or micro-detail. It offers a much more agile, high-resolution copper performance—giving heavy riffs all the visceral body they need while easily keeping pace with fast, complex metal tracks.
To my surprise, it actually sounds much better for metal than my regularly used Effect Audio Ares S copper cable, which can feel a bit too slow and heavy on rapid double-kicks or dense walls of sound. The Epsilon Mk II keeps every instrument separated, punchy, and crystal clear."
My 2cent impression is based on:
Dac: AK sr25mk2 (Neutral-warm,energetic,intimate)
Iem: um mest jetblack (quadbrid)
Cable: Null Audio Epsilon mk ii
Termination: 2.5 balance
Eartip: Electech baroque stage
Genre: metal(metalcore, tech death,post hardcore)

Very nice cables, very happy with my purchase, much better than the stock Sennheiser cables.
Thank you, Paul! We’re delighted you’re happy with your Ethos Ultra cable and that it’s a worthwhile upgrade from your stock Sennheiser cable. We truly appreciate your support.
Actually very good quality I love it and I’m a pretty hard person to please.
Thank you, Austin! We’re delighted you’re happy with your Lune series cable and that it’s a worthwhile upgrade from you. We truly appreciate your support.
Reshell was done right for my 64 Audio A18t, recommended!
Hi CHEE JEREMY, thank you for the recommendation! We’re delighted you’re pleased with the reshell of your 64 Audio A18t. We appreciate your support.
Sennheiser IE600 now more dynamic with the 8-braided Tiburon cable. I considerer the sound of these IEMs „too flat,“ but now I really enjoy it, with the 8-braided Tiburon cable.
Hi Jiří, thank you for sharing your experience. We’re delighted the 8-braided Tiburon cable has brought a more dynamic sound to your Sennheiser IE600 and made them more enjoyable for you.
This is worth way more than they charge. Quality of materials and build alone should make them 2x the price.
Needed a replacement Bluetooth cable for when I use my IEMs during my marathon mowing sessions 😂
This one got great reviews and lasts 4 times as long as my last one. Very happy with it!
I replaced the cable on my Shure in-ear monitors with this cable. I am very happy with the cable.
Great!!! The service was amazing and the package came on time. I ordered per FedEx Express Germany and all went smooth and fast. The quality + unboxing made me feel i have purchased something fancy and they are great for touring with my bands. No problem since (2 months). Keep in mind though the shipping costs are high and depending on what country, you'll have to pay custom service fees.
Just got the cable for my IE600, The difference between the factory cable and this one is day and night. Highly recommend.
Belle , leggere , grande suono , grande autonomia.
I bought these as a replacement for the stock cable on the sennheiser IE200. The custom IE300/600/900 connectors fit great. Cable feels a lot more premium and conduct less outside noise, would recommend!
Both cables are reliable and high quality. I use Sennheiser IE600 and the connectors are accurate. Perfect. Delivered to the Czech Republic
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.
Great quality. Very well put together. The upgrade is well worth the money to spend on the 8 braid.
I actually bought these as an impulse and planned to return them, but damn they are so nice. Paired them with my IE200 and now they feel like a $500 IEM. The finish is silky smooth and the cable has literally no memory, and I can’t notice any microphonics, Would definetly buy these if you look for a set of cables. Case as a nice bonus and they even give you a card with your name on it
Belle , leggere , grande suono e grande autonomia.
The cable works great. I use it when I work out with my IEM’s in. I like it a lot. The only suggestion I would make is for it to tell you the percentage of battery life left. That’s it. Everything else is perfect.
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!
Thank you for making an affordable option for the UEP pros to make them Bluetooth compatible. The sound will obviously be slightly degraded simply because it’s Bluetooth, but to allow me to use these without a wire has been fantastic thank you, great product.
As many have written before, the connection of the standard cable to the ie 600 are very loose and I hat issues with the sound cutting out repeatedly. These cables have a much firmer connection, plugged them
In once, havent had to readjust since.
Also have to point out the quick and friendly response via whatsapp. All in all highly recommended.
The cable of my Sennheiser IE 300 failed far too quickly, so I decided to purchase the Ethos Series MKVI Premium from Null Audio.
The entire process — from ordering to delivery — was exceptionally pleasant and clear.
I had high expectations for this cable, but I can now say that those expectations have even been exceeded. The cable looks exceptionally high-quality, but it’s the sound that surprised me the most. I was already very satisfied listening through the Dragonfly Red, but with this cable everything sounds even more open and detailed.
In short: a top-tier product and excellent service from Null Audio.
