Derived from the shielded upgraded cable BC125A Air Ocean, the main core of the M120A is made of high-purity OCC, with an individual signal-positive pole up to 25.6AWG. Thanks to the shielded structure, the cable is soft and also very resistant to pulling, making it convenient for everyday use.
To not affect the continuity of the main channel signal cable, the in-line controller is designed at the split position, using two separate and thinner silver-plated wire conductors to complete the microphone circuit.
Designed with a straight-down connector, the M120A fits perfectly with classic earbuds
and in-ear monitors for straight inserting. And it can also be used with in-ear monitors for over-the-ear wearing.
