Connect your player, DAC and amp in the same wire as your IEM cable. Choose from nine Null Audio and Symphonym wires, from Ethos MKVII to Istana, a length from 10 cm to 2 m, and the plug on each end: 2.5, 3.5 or 4.4 mm, a 3.5 or 4.4 mm female socket, 6.35 mm, XLR, RCA or USB. Handmade to order in Singapore.
Choose the wire, the length and both plugs below. The price updates as you go.

Premium Interconnect
Short links for a DAP and amp stack, adapters for a balanced output, or desktop runs to an amp: built in the wire you already trust, with the plugs your gear needs.
Wire
Every wire on the list is the one we use in a Null Audio or Symphonym IEM cable: silver-plated copper in Ethos MKVII, UPOCC copper in Arete and Epsilon, silver/copper alloy in Lune, 7N copper, silver/copper and silver in Tiburon, Hakone and Thera, the gold-silver Tri-Hybrid of Aoraki and the graphene-coated copper of Istana.
Choose the same wire as your IEM cable for one signature from source to ear, or pick another to tune your system.
Plugs
Both ends offer the same choices: NL4 plugs in blue at 2.5, 3.5 or 4.4 mm (3.5 mm also balanced or L-shaped), 3.5 and 4.4 mm female sockets, a 6.35 mm plug, 3-pin XLR pairs, a 4-pin XLR, an RCA pair, and USB-C or USB-A.
A female socket at one end makes an adapter, for example a 4.4 mm balanced cable into a 2.5 mm player.
USB-C with a DAC built into the plug (ALC5686, or ESS9280C for higher resolution) turns a phone or computer into an analog source for the plug at the other end.
Length
Set any length from 10 cm to 2 m in 2 cm steps: about 10 to 15 cm for a strapped DAP and amp stack, 30 to 50 cm for a short desk link, and up to 2 m to reach an amplifier or powered speakers.
The price follows the wire and the length, so a short link in a premium wire stays affordable.
Line level
RCA and 3-pin XLR come as left and right pairs, for line outputs, amplifiers and balanced desktop gear. A pair at one end and a single stereo plug at the other splits the signal into left and right.
A pair needs two runs of wire, so the wire part of the price is doubled.
Connect your player, DAC and amp in the same wire as your IEM cable. Choose the wire, the length and the plug on each end in the configurator; the price updates as you go.
Handmade to order in Singapore; lead time around 1 week. For another plug, or longer than 2 m, contact us.

Interconnect Cable customization
This is another awesome product... The interconnect cable that links you to your iphone! It really make listening music so much more pleasurable! I got the one with USB-C connection made with Thera MKIII UP-OCC Cryo silver cable that is the same as my ASH7 IEM cable. It really does make a huge difference! Although it is a bit pricy but it is definitely worth every penny!
Excellent interconnect
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.
Cable is Good!
There was a delivery error from Fedex, but I am fully satisfied with the result of receiving and listening. I'm very busy with my work, so I'm leaving a brief review late~
The 4.4mm Female to 3.5mm Male interconnect is exactly what I need.
Sony Walkman has been always my primary source, I haven't met any problem until I sign up Spotify to hunt for new songs. I have been having trouble using 4.4mm on my laptops, and iphone, nor it will connect to my iFi Audio Micro DSD. Thanks to the interconnect the problem solved. I live in Malaysia, shipping is not an issue, it arrived around the third day of the shipment.
4.4mm female interconnect to 3.5mm male
this is my 2nd purchase from NA.Excellent build quality. Reason for not scoring full is the 4.4mm female adapter. It's kind of big (and squared) and it's not like the usual rounded adapter. However, it does not affect the SQ.

1. I have the Hakone cable. It's a bit stiff. What cable is your softest and most flexible?
2. How much would a 1 foot 4.4 mm male to 4.4 mm male interconnect cost?
1 foot (about 30 cm): order our Premium Interconnect cable, choose 4.4 mm plugs on both ends and set the length; the configurator shows the price.
Can customize this to 3.5 male ~ 3.5 male angled connectors.
Length about 1m.
If yes, how much and how long will that take?
Yes. Order the Premium Interconnect cable: USD 40 base plus length by the wire you choose, and add "angled 3.5 mm plugs on both ends" in the order note. It is made in about 1 week.
I would like to buy 2.5mm 4pole to 2.5mm 4pole cable.
Can you make it? and how can I order it?
Of course, please send the length you require to support@null-audio.com. We will make quotation and preparation accordingly, thanks!
Would you be willing to make an 8in Lune series cable for my dac/amp combo? If it works out I'd come back for 2 more matching 5ft Lune series cables to match if it were possible?! If so how much would it cost per each item?!
Thanks,
D
Hi Darryl, of course, we are open to any customization requests. Please reply directly to this email to provide more details such as connector and etc. We will arrange it for you. Thanks!
Questions
Every interconnect is built to order by hand in Singapore. Lead time is around 1 week.
For one signature from source to ear, choose the same wire as your IEM or headphone cable. Otherwise pick by character: each wire’s own product page has a sound guide.
The price starts with the build and both plugs, then adds the wire at its per-metre rate for the length you set, so a longer or more premium wire costs more. XLR, RCA, 6.35 mm and USB plugs add a surcharge, and an XLR or RCA pair on either end needs two runs of wire, so the wire part of the price is doubled. The total shows in the configurator before you add it to the cart.
Yes. Choose a 3.5 or 4.4 mm female socket at one end and the plug your player needs at the other, for example a 4.4 mm balanced cable into a 2.5 mm player.
USB-C (data) and USB-A carry digital audio, for example from a phone or computer to a USB DAC. USB-C (ALC5686) and USB-C (ESS9280C) have a DAC inside the plug: plug them into a phone or computer, and the analog plug at the other end feeds your amp or speakers. The ESS9280C is the higher-resolution DAC.
Contact us or WhatsApp +65-8731-5476 and we will check what we can build.
Standard builds can be returned within 14 days of confirmed delivery if unused and in their original packaging. Change-of-mind returns carry a 30% restocking fee, and shipping is not refunded.
Custom spec, length or connector builds cannot be returned for a change of mind once production starts. Faults are a different matter: every cable has a 1-year warranty, so contact support@null-audio.com and we will assess it.
