Great product, work well. I like it

I'm not one to write reviews, but felt the need for this. Sent my SE846 for a reshell (not custom). They had the Trishd mod and sounded fantastic. Now, they sound even better... Blowing my best expectations out of the water. Folks, don't hesitate.

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

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.

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!

It was delivered very fast, thank you. Quality looks very good. Have not used it yet as I am still waiting for th delivery of my custom IEM

The cable was exactly what I wanted: and ie600 stock cable replacement that was snug (tighter than the original MMCX connection) and more malleable/comfortable cable. High quality build, excellent packaging and nice case (using it instead of the sennheiser case) sound quality is as expected: equal to/better than the stock, which is what I needed. Looking at getting the 4.4mm as well, so I can benefit from the power difference in the ifi goblu 4.4mm port from the 3.5mm. Although my Chord Mojo is still my laptop go-to DAC/amp which is 3.5mm only.

Mega cabel poprawił mi się szczegółowość i basy są lepsze polecam ten cabel lepszy zdecydowanie od standardowego IE 600 Senheisser sluchawki douszne

The cables are really a Jem

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

Null did an awesome job with the reshell of my W60’s. Solid work and what a big difference using these acrylic molds instead of foam inserts, great job Null!

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

iem cable much better than stock and a return shipment of a mistaken order on my side was no problem to handle and refund. cheers

I bought this cable with the Sennheiser connections, because I have a Sennheiser IE600 IEM. My main priority with this purchase was a good fit with my IE600, because the IEM uses a slightly different MMCX connector. I have never spent this much money on a cable before, but options are limited for the IE600, so I decided to take the plunge.

The Ethos cable I received fits my IE600 perfectly. It is more snug than the original cable that was included by Sennheiser. If you are looking for an IE600 cable that fits, I can confirm that this one worked for me. I am giving this cable 5 stars because it does exactly what I bought it for.

Other things I can say is that the cable feels nice and thick, it does not tangle, and it is pleasing to handle. The white color is attractive.

Not cable-related, but Null audio sent the cable in a nice leatherette case. The leatherette case was inside of a nice embossed cardboard box. I now use the cardboard box to store my IE600s (perfect size). I use the leatherette case to store a different pair of earbuds. In other words, the packaging and unboxing was very nice.

For reference, here is exactly what I ordered:
1x Ethos Series MKVI Premium Upgrade Cable for Headphone | IEM for $0.00 USD each Headphone Connection: Sennheiser IE300/600/900
Stereo Connection: NL4 Rosegold 3.5

These are amazing cables that I have ordered and I have observed an improvement in the sound quality on my HiFiMan Sundara headphones.

Genuinely one of the best cables I have used for the ie900. Originally had issues with treble peaks and just overall harsh treble for the ie900. Ethos VI completely fixed that for me, and added a tone of excitement to the pair.

Null Audio won't fail you.

I recently purchased a 4.4 mm male to 4.4 female interconnect and as a bonus surprise Null Audio upgraded it to an 8 wire copper the same as the 8 wire Tiburon I had purchased in the past. This is a wonderful sounding interconnect that is warm with accentuated bass without sacrificing details. As always the workmanship is top notch and unsirpassed for the price in my opinion.

This is the second cable I have purchased from Null Audio, the first was a massive improvement over the O/E that was supplied with the iem's, the Aoraki is a game changer. In real terms I've only had a limited amount of listening time with the new cable compared to 3 years with the previous one, the difference is incredible, it's more musical, the sound staging sounds wider than before, it's another level, I'm delighted with the purchase and cannot wait to enjoy it more.

Cable looks and feels great. Would buy it again.

The service and response from Null Audio was very prompt attending to my product queries. This had enabled me to place the order for the Thera cable. Delivery was also very fast.

I enjoyed the Thera sliver pairing with the Hifiman HE1000. The highs and timbre are airy, coupled with a good mid texture. Bass is well controlled with right amount of slams. This is a good cable punching above its price.

I've finally come around to write my review for this great cable after having used it extensively for more than a month. I bought this cable as a replacement for the stock cable of my Sennheiser IE 900. While I really like most of Sennheiser's products, I've always found their stock cables a bit lacking. This was true for my HD 800 and applies to the IE 900 as well. I've bought other cables from NA in the past, namely the Lune MK V, which I use with my Shure SE846 and really enjoy. I can say the same thing now about the Tiburon. The body and layering seems much fuller and the sound staging is slightly improved as well. I can only recommend this cable.

Fantastic IEM cable, a great improvement for my Sennheiser IE 300's. Easy purchase and excellent customer service.

Thank you.
