A hand-built upgrade cable for most headphones that use dual 2.5mm connectors. It fits the Sennheiser HD 700 and older HiFiMAN headphones such as the HE400S. Every cable is made to your spec. Choose the length, the y-split length, the sleeve colours, and the amplifier-end termination to match your source.
Durable nylon weave covers hand-braided OFC copper. Reinforced strain relief protects the points where the cable meets the connectors. Your choice of amplifier-end terminations from audiophile and professional-grade manufacturers, including Neutrik, Viablue, Furutech and Amphenol. As standard, the y-split is finished with our own splitter, designed in-house and CNC-machined from aluminium, then sandblasted and anodised.
Assembled and soldered by hand, then thoroughly tested before it leaves the bench.
Hand-built to order in London. Shipped in 100% recycled and recyclable packaging with minimal branding. To keep it at its best, gently coil when not in use and wipe with a damp cloth to clean.

Felt a bit stiff at first, but after using it awhile it is now quite supple. Great splitter options.
Morgan Davis –
Arrived super quickly, and look fantastic as expected. Great color selection.
Alex –
Great headphone cables, wasn’t sure if the cable would work with my headphones (HE400S), but Cxnnected was super helpful and answered my questions.
Ryan Getts –
Super solid cable, well made, excellent craft.
Samuel –
Colours match the pictures, solidly built, with connectors you’d struggle to find elsewhere. I should’ve replaced my threadbare stock cable a long time ago!
