Bought to upgrade a broken Sennheiser IE200 cable with an in-line mic. Fully worth it! The cable is far more solid, has great build quality, and sounds excellent (admittedly not an audiophile as you can tell from the 200s, but do enough audio editing to confirm it is equal or better than the stock cable). Most importantly: The Null Audio support staff was super helpful when I asked for MMCX connector—without knowing Sennheiser uses a modified version of the industry standard. They thankfully pointed me toward a Sennheiser connector and it works great. They also were generous working around unforeseen stock issues. Wish all of my customer service experiences could be this good!

I bought these with the connectors that are compatible with the oddball Sennheiser MMCX. The cables are nice and thin, and don’t put any undue strain on the small light weight IEM. I had an effect audio cable on my set prior, and it kept causing them to unseal, because the cable was too thick and heavy. Plus it was three times the price for not three times the improvement. Having bought various aftermarket cables, Noel is my new go to for value and quality.

I am really happy with my purchase, the cable feels nice and has a low profile without the bulkiness many cables have. Sounds good and it's a clear upgrade compared to the stock cable of my Sennheiser ie600.
There are many options to customize the cable, only lacking RCX connection for FIR Audio, otherwise probably I would have already bought a second cable from NULL Audio to upgrade my other pair of IEM.

Best cable ever.

I was looking for a more durable and precise cable for my etymotics. The cable came quickly and is just as described.

I bought from Japan.
Ethos is best IEM cable for me.
Sound is nothing to say.
Touch feeling is very good!
Covered by cotton?

Anyway you should buy it!
