    Sennheiser IE600 now more dynamic

    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.

    Pairs well with A18t

    My first time trying out a Null Audio cable with my 64audio A18t and am very impressed with the Tiburon MKIII customized with USB-C and mic. It's my daily driver for my commute with iPhone + Apple Music Lossless. Thank you Null Audio!

    Copper Magic w Tiburon

    I've got great IEMS, and I am constantly searching for ways to 'hear' more into my music. The Tiburon 8W is SUPERB. It opens up music like a microscope. Not harsh the treble sounds fantastic. The bass is DEEP, intricately layered, not boomy like with some thick copper cables. Basically, I'm blown away. The cost/performance is absurdly balanced towards the performance with Tiburon. STRONG recommendation to try on all your IEMs.

Sounds great. Poor material

I was super excited to get my cable. It arrived a little late, which isn't a problem. This issue is the connectors are super cheap, they look like cheap plastic that you would use on a $20 set. Not the quality I was expecting from a $200 product. They dont look like anything in the photos either. Very disappointed. The sound quality is superb to be expected though from a pure copper cable. Oh well you like and you learn.

Amazing sound. Beautiful look. Prompt shipment.

I am impressed of how quickly I received my order(from Singapore to USA). Then I am super impressed of the beauty and quality of the cable. I can look at it all day long. Third, my cable has 4.4mm balance plug and the sound is amazing. I am sure after more hours of use, it will sound even better. Now I am deciding to get another Null cable for my another setup. Keep up the great work!

This Cable is very beautiful and rather soft

Great do it all cable!

The cable came quick and is well built. The color is slightly lighter than the pictures but still looks fantastic. I noticed on my hybrid iems the bass had more punch and the treble is clear but calmed down a touch. Would highly recommend! Great job to the Null team!

Wonderful with the Andromeda - Wonderful on all categories

Firstly hats off to to Su and the Null Audio team. This cable (I ordered the Herringbone 8 braid upgrade also), is the best thing that ever happened to my CA Andromeda. This takes the Andros to a whole new league. Now I can hear every mid-bass 4-string bass notes clearly which I struggled with so many IEMs - along with prominent micro details. A perfect cable in my collection. On top of that, it's so beautifully built. Just see the pictures and you will know that this will last the test of time. Looks amazing, built amazingly, sounds wonderful across all frequencies. On top of that, what a wonderful packaging and unboxing experience. NA really makes their customers feel special and embraces us into a family. That's the most commendable feat of Null Audio's part. A myriad of praises.

PS. After this, I have already ordered two more cables from NA. They are THAT good.

Brenn (Huntington Beach, US)
nice quality. but a few negitives.

the overall sound quality is a slight improvement over my stock FH7 & FH5 cables and the cable feels sturdy and well made and the packaging is A+ but i do have a few downsides. only sound negative ive had is a very slight buzzing in the left channel with a much louder buzzing in both channels at random when the center of the cable is bumped or moves occasionally.
my MMXC plugs did NOT have the blue and red coloring like they do in the photos and instead have a small slilver/light gray L/R and is a royal pain to find. in addition my left MMXC plug is very lose on my Fiio FH7 & FH5 (no other MMXC cables i have are this lose). and the final negative for me at least is the Hardware sleeve is obscenely heavy and is constantly pulling the cable down across the back of my ears. (my scale unfortunately is broken at this time but i would say it weighs a bit more then a 6.3mm to 3.5mm adapter).

Awesome Custom Cable!

Got this for my E-MU Teak headphones to replace the decent but super thin upgraded cable. The Sennheiser HD59X connectors are compatible with the 2.5mm jacks on the E-MU. Important note that the E-MU jacks are cabled for tip = signal, ring = return, sleeve = no connection. I confirmed this with E-MU support so that I didn't have to send the cable back right away. Null Audio support was great and actually got my package back from FedEx to re-wire them because of a late reply from E-MU. I went with the African Padauk 3.5mm straight jack and splitter which looks great with the Teak headphones. The copper/bronze color of the cable nicely compliments the wood as well. The only thing I'm not a huge fan of is the chrome finish of the 3.5mm connector and splitter but matte finish of the 2.5mm connectors. The metal on the E-MU is matte silver and matches the 2.5mm connectors so it ended up working out just fine - just not a huge fan of chrome finish. I and had it customized to add 24" of length before the splitter to make it a ~6 ft cable. There is absolutely no cable memory or microphonics. I like that the cable has a decently thick braid (thicker than the old cable) but not a huge, heavy rope like Fostex cables. A herringbone 8-cable braid might be even better but I didn't want to spring for it. Overall a great cable and equally good customer support!

Excellent cable

I purchased the Tiburon UP-OCC Cryo Copper Headphone/IEM Cable with 8 braid upgrade to go with my CIEM's instead of using my unbalanced 3.5mm cable. Straight out the box there is slightly more detail, wider sound stage and separation with a nice warmish sound which is how I like it. With some burn in time I can see these only getting better. These are very well built.

Great!!

I replaced it from the lune cable for ue tf 10. Product making is better than before. Processing of earphones' side connectors and left and right branch points is beautiful. Of course, the sound quality is also the best. This time I got confused as to whether I should purchase the earphone body and portable amp, but all this cable was solved. If you like music you absolutely should buy.
