Everything you need before you order — how the modular system works, which connectors fit your headphones, and the hardware we build with.

the modular system.

If you own multiple headphones or switch between portable and desktop setups, you’ve faced the tedious reality of cable management: different headphones require different connectors, different amplifiers require different terminations, and before long you’ve accumulated a drawer full of cables you swap between constantly.

RE:CXNNECTED eliminates this. Each cable consists of two components: a Y-Split that connects to your headphones, and a Core Cable that terminates at your amplifier, DAC or DAP. These join via a secure push-pull balanced connector, allowing you to swap configurations in seconds without repeatedly stressing the connectors on your equipment.

how it works

Build your system around the headphones and sources you own. A single Core Cable terminated in 4.4mm Pentaconn can connect to Y-Splits for your Sennheiser HD800 series, Audeze LCD-X and Focal Clear. Acquire a new amplifier with 4-pin XLR? Add a Core Cable rather than replacing everything. The modularity means your investment grows with your collection rather than being replaced by it.

available configurations

Y-Splits are available for most major headphone brands including Sennheiser, Audeze, ZMF, Focal, HiFiMAN, Beyerdynamic, Meze and Dan Clark Audio. Core Cables can be terminated in 4.4mm Pentaconn balanced, 4-pin XLR balanced, 2.5mm TRRS balanced, 6.35mm single-ended or 3.5mm single-ended. All components are hand-made in London with premium connectors from Furutech, Neutrik and Viablue.

choosing connectors.

Connectors from Rean, Amphenol, Switchcraft and more to suit a range of headphones.

Different headphones use different sockets. Here’s what fits what — and what each connector is made of.

single 3-pin mini XLR

For AKG and Beyerdynamic headphones — K7XX, DT1990, DT1770. It is not possible to make these cables balanced without modifying your headphones first. Clicks into place and releases via a latch button. Only Switchcraft connectors are currently used for these cables: gold-plated copper contacts in a nickel-plated copper alloy housing.

dual 4-pin mini XLR

Most commonly used by Audeze; also fits Meze Empyrean and ZMF headphones. Clicks into place and releases via a latch button. Available from three manufacturers:

Rean — the industry standard, and likely the connectors your Audeze headphones came with. Gold-plated bronze contacts in an aluminium and zinc housing. The rubber boot helps with strain relief and keeps these connectors lasting.

Switchcraft — the original: Switchcraft first introduced the mini XLR. Silver-plated copper contacts in a nickel-plated copper alloy housing. The latch action is smoother than the Rean.

Furutech — very similar to the Switchcraft, with rhodium-plated contacts.

dual 3.5mm

Used by all recent HiFiMAN and Focal headphones — other manufacturers may use different wiring schemes, so please get in touch if you’re not sure. The most common type of audio plug. It doesn’t matter whether the individual plugs are stereo or mono — they’re all wired the same — and every option fits the recessed sockets on HiFiMAN and Focal headphones.

Amphenol — gold-plated brass contacts in a die-cast zinc alloy housing with a chrome finish.

Rean — gold-plated contacts in a nickel-plated brass housing.

Viablue — 24k gold-plated contacts in a matt black aluminium housing.

Furutech — rhodium-plated contacts in a stainless steel housing.

splitters.

The junction where the left and right channels part ways. Every headphone cable includes one — two options:
Cxnnected machined splitter — sand-blasted, black-anodised aluminium with laser-etched channel markings

Cxnnected. splitter

Meticulously machined by Cxnnected from sand-blasted, black-anodised aluminium. Laser-etched left and right markings, so you never mix up your channels. Secured by two bolts, keeping the cable perfectly centred. Slim, compact dimensions: 19 × 12 × 12mm.
Viablue splitter — sand-blasted, black-anodised aluminium, single-bolt design

Viablue splitter

Sand-blasted and black-anodised aluminium. No left or right markings. Secured by a single bolt. A larger, more substantial design: 30 × 15 × 15mm.
