Having purchased a couple of Null Audio cables for my other IEMs, I was looking for a budget option to replace the stock cable for my IE-200. I thought I was going to get a so-so product but the clear mids and highs, the matte black finish and the simply excellent accessories in the package are simply unbeatable.

Cable feels great, much more well behaved compared to the stock cable. MMCX connection is nice and tight as well. Great job NA! 👍

High quality product and packaging. Flawless.

A3H+ Lux CIEM was an excellent choice in that price range. These are hidden gems, and can out perform some of the well know brands. The custom shell and fit took approximately 8 weeks to complete, and around 4 days to receive in the USA.
The A3H+ Lux sound can bounce between 'neutral/cold' and 'neutral/warm' depending on the media you are listening to. It has an impressive low end, crisp vocals/mids and highs. All detailed and articulate.
The bass is punchy with emphasis on the mid bass as opposed to Sub Bass/Deep Bass (IMO). The bass hits nicely and powerful. it's crisp and accentuates the track without mudding the mids or vocals.
The soundstage is airy and a bit narrow, which for me is perfect. I find that too much air can result in a hollow sounding experience with some distortion. The vocals are clear and detailed. I would say that the
A3H+ Lux has a V shaped sound signature, balanced and accurate.
These have a spectacular three-dimensional sense of separation. Meaning... you can hear every instrument being played as it moves all around you while separate from the mids/vocals.
The A3H+ Lux also comes with 4 signature sound settings that you can adjust to your liking. (Vocal, Normal, Vocal +, and Bass)
*This IEM does not do well with bass boosted tracks. If you prefer majority of bass boosted music, these aren't the ears for you.
The A3H+ Lux is a versatile IEM.. meaning - (depending on your DAPs power/ and settings) you can tweak the vocals by moving them to the front of the soundstage or bring the vocals to the middle of the soundstage and let the music encase the vocals.
*CONS -
SubBass /Mid Bass is great, but I wish they would hit a little harder in the deep bass range. I have yet to find an IEM that can successfully pull it off.
A side note to AAW- please make an IEM that can render rumbling Deep bass while maintaining that wonderful upper/mids/vocal clarity.

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 recently purchased the Sennheiser IE 600 and found the stock cable to be lacking, especially for a high-end IEM. The Brevity Pro fron Null Audio is a fantastic replacement! It is quite soft, not microphonic and the connectors are a perfect fit.

VERY GOOD

I have purchased this cable to use with AUDEZE Euclid. It is perfect fit to it. Sound is good and also the black color is really good.

I've been pleased with the look and feel of the Epsilon cable for my IE600. It is less microphonic than the cable that shipped with the headphones and has a much sturdier connection to the IEMs than the stock cable, which had been prone to shorting out when I moved my head. Sound quality is excellent, though I'm not sure about the particular advantages there versus the original, given that my original OEM cable may have been faulty. Overall, it is extremely comfortable, not microphonic, sturdy, and premium in fit and finish in all areas. This was my first purchase from Null Audio, and I am quite pleased. I am very likely to order from them in the future. Highly recommended!

The case was delivered quickly and quality was fantastic. Looks clean and simple.

Luna MKVII unleashes the potential of IE600, highly recommend!!

Highly recommended for Sennheiser IE 300: better fit, great sound quality.

P.S: An additionnal fee for customs duties / import tax purposes should be expected depending on your country.

I use these on my sennheiser ie300 iems and this makes them infinitely more usable. This cable is far superior to the original cable. It is flexible, does not hold memory and is not microphonic. Highly recommended.

Sounds so much better than stock cable that came with earphones. Separation and clarity is excellent.

It brings me powerful bass due to the use of copper cables and clear high range due to the use of silver cables
