Using FiR's proprietary tubeless design and the 3rd generation atom pressure release system, the M2 presents its lightly v-shaped sound with a vast soundstage and pneumatic pressure-free experience ideal for guitarists, drummers and bassists, that redefines what is achievable at this price point.

The Revolutionary RCX Connector

 RCX (which stands for Rigid Coaxial) is a revolutionary socket and connector design pioneered by Bogdan and his team. Recognizing the advantages and disadvantages of 0.78mm 2-pin and MMCX, FiR Audio has created a connector and socket design that manages to far surpass both of the incumbent standards in both durability and ease of use.  

The coaxial natural of the RCX with the locking mechanism of the four quadrants on the male connector with the female socket allows for a very secure connection between the cable and the in-ear monitor that prevents the IEMs from separating easily from the cable even after repeated plug-in cycles. The square profile of RCX prevents swivel and looseness of the connector, as well as creates a barrier around the socket from sweat and excessive moisture when the cable is connected. Great characteristics for the touring musician - that's why FiR Audio cables on our IEMs have a 3-year warranty!

Why Tubeless Design?

  • Tubeless design allows you to work with much more air volume hence less “pipe” pressure from a tube pumping sound into your ears.
  • Sound is delivered in a much more linear manner giving you a  coherent frequency response   and better sound. 
  • The occlusion effect i that you find in other brand of IEMs is minimized
