NocturnaL Audio Onyx Copper Upgrade Cable

  • Based upon the popular Quad29 with improved with premium materials & components!

  • 30-strands of High Purity Copper per 22AWG conductor for great bass & mids without sacrificing treble

  • Proprietary treatment with Oxide-Inhibitor Compound (OIC) to prevent oxidising

  • High quality silver solder for all connections

  • Carbon-fibre rhodium-plated 3.5mm straight connector (compatible with most mobile phone cases)

  • Carbon-fibre metallic black Y-split with clear tube slider

  • Meticulous hand-braided construction, just like the higher end models

  • Ready stock & no build time required! (Unless indicated as pre-order)

  • Comes with choice of MMCX & CIEM 2-pin connectors [CIEM 2-pin variant discontinued by manufacturer]



Based upon the popular Quad29 model to fill the gap for those who cannot wait for the custom built cables, the Onyx features extra premium touches to bring both aesthetics and performance to the next level.

Fitted with a Rhodium plated 3.5mm Carbon Fiber connector, the extra durable plating holds up to repeated usage much better compared to standard gold plating. High quality silver solder is also used in when crafting the Onyx, minimising any weak links between the wires and connector for optimal performance. The custom designed Carbon Fiber Y-Split completes the premium appearance, complementing the 3.5mm connector's design.

For those who need the extra performance over the regular Quad29, or those looking for a super sleek cable at an affordable price tag, Onyx is the ultimate choice.

  • Onyx (CM) has the 2-pin barrel pin connectors compatible with most custom in-ear monitors (CIEM) with 2-pin sockets (recessed supported, except Unique Melody), and all other old Westone UM series and W4R.

  • Onyx (MX) has the MMCX pin connectors compatible with the new Westone W and UM series, Shure SE series, Logitech UE and Ultrasone IQ earphones.
