Thank you for choosing a Linum® cable. We hope it will exceed your expectations and revolutionise your audio experience.

To ensure best possible user experience, please do read this manual carefully and follow the instructions to your best. 



For the best audio experience, the cable plugs must be fitted correctly into your ear pieces – red for right. Your Linum cable is colour coded on the plug. 

Press on the plug. NEVER press on the cable. If recessed, press the plug in place using a soft tool or your nail. 

2-Pin: The red dot MUST align with the red marking on your ear piece and the blue dot MUST align with the blue marking. Make sure the coloured dot side of the plug is upwards.

MMCX: Due to the high variation of MMCX connectors in the market, estron cannot guarantee a perfect fit to all MMCX earphones.



Pull the transparent part of the cinch to unlock the slider. When unlocked, place one finger on each side of the cinch on the narrow side and slide it in place. Push the transparent part of the cinch back in place to lock the slider.






To disconnect your Linum cable from your ear piece, pull the plug straight to avoid damage to the sockets. Pull the plug, not the cable!

T2™ Special (recessed)

When unable to pull the plug, pull the cable gently. To avoid damaging your cable, wire it around a finger and apply a straight steady pull.


For further guidance please see



When not in use, we recommend pulling the cable cinch almost all the way up to bring the ear pieces together. Wrap the cable with a small winder and store it in a case with small pockets to keep the cable in place.

Check for our cable accessories.

TangleLess™ feature applies to Music and BaX™ versions. Return your cable to its TangleLess form holding the cable high by the ear piece sockets. Then lower the cable onto a flat surface. You will see that the cable automatically coils back into its preformed shape. Watch our video on



Excessive heat may influence the TangleLess effect.


Clean using damp cotton cloth only. Do not use solvents or cleaning agents. Be aware that liquid submersion voids the warranty. Made from natural materials, some patina is to be expected over time.



Keep your Linum cable dry and out of extreme temperatures.  Never leave in direct sunlight throughout longer periods of time.



Store your cables with your earpieces in a clean, dust free environment, e.g. a Linum organiser, available on



Avoid frequent and sharp bends that may deform your Linum cable and cause the cable to lose its outstanding acoustic clarity.



Choking hazard. Keep out of reach of children, this product contains small parts. Use with adult supervision.



The Linum cable is very strong and thin. When disconnecting, do not pull the cable with extreme force, this can damage your fingers.
