Thin, ultra strong and durable

Linum cables are thin. Very thin! In fact they are only 0.9 mm. But don’t let that fool you – although Linum has a smaller diameter than you are accustomed to, they are much stronger than any ordinary earphone cable.

Light weight cable with ambient sound

A Linum cable weighs 4-8g! So you might not even notice wearing it – unless of course you are listening to your favourite track. No doubt it will sound better than you have ever experienced it before!

Look cool and less wired up

Linum cables do not really weigh much – in fact they are so discrete that they are almost invisible. The Linum range was aesthetically designed to make you feel naturally cool and less wired up. That is why Linum cables are perfect when performing on stage and/or for use in broadcasting and security.

Soft and skin friendly

Linum cables are so soft they feel like a second skin. That means that they feel good during extreme sporting activities and are suitable for a long duration under your clothes. They even fit perfectly under helmets. If you prefer to wear your cable on the outside, you will appreciate the low mechanical rubbing against your apparels.

Validation Test


Plug inserted into and extracted from the socket 500 cycles followed by an intermittence test in an electric circuit. Manipulation of the plug by hand, turned and wriggled for 20 seconds in the socket.

Socket was tested more than 2000 cycles with a new plug after each 500 cycles.

No intermittence was registered.


Artifical Sweat Test

Sweat test 6 hours at 60 degrees celcius, PH 4.7. No sign of corrosion.

Pull Force

Pull force test demonstrates minimum wear on the socket. Pull force at minimum 5N after 2000 cycles.
