The original Magnetic Wave Absorber, MWA series, was first released in 2009 and become very popular for its sure effect against noise generated by electric magnetic waves around equipment.
MWA-RC was created by the development that was applied to this MWA material for an RCA cover cap to prevent EMA, noise and dust altogether with very easy usage just simply attach it onto the RCA jack sockets.
These caps can be installed by simply putting them onto unused RCA jacks on your equipment. The hardness controlled material helps with damping the tiny vibrations of the contacts. And the electric magnetic wave absorber on the top contributes to attenuate noise generated by power signal flow. In addition, it is absolutely effective to prevent dust and humidity which causes degradation of contacts and troubles for connections.
Considering cost these caps are fine for just keeping dust out but also improve sound very slightly.
