Cable is a premium cable. Love the feel of the cable and it doesn't tangle. Really like the connectors as well. Very nice.

Best replacement option I’ve found for my Sennheiser IE 300! Build quality is phenomenal! Additionally, the support I received from the NA team was outstanding!

Superb in, Stunning out cables. This is my first NA Cable, outstanding effects on my AK Zero1: wider sound stage, more details, tight bass and sparkly treble, forward mid a bit. The weekness on my Zero1 is the quite tight soundstage but Ethos MKVI solved the problem wisely.
The metal part (Black/Silver) is match perfectly with my AK SR25mkii n' Zero1!
The leather case is well made as well.
The service center (dont know exactly who) is very kind and helpful, served my requesting in deep.

Can't not wait to try more iem cable from Null Audio soon!

Worth buying in every aspect such as design, fitting, sound and price.
Perfectly matched with IE600, better than the previous MKV.
NA, pls keep making cables like this

The connection between the wire and the mmcx is very very secure and it fits perfectly on my IE600 no loose parts at all. The wire is slightly angled on the mmcx to naturally loop behind your ear. I've bought other 3rd party cables for my iem and nothing has come close to NA's attention to detail

Purchased as a replacement for the default Sennheiser IE300 cable, that was starting to cause issues. My first impressions after the first 2 weeks of daily use are very positive so far.

Iinital installation was a bit scary, because the connectors require a lot more force to be pushed in compared to the default ones.

It also came with a nice bag and a ownership card
