ReSound SureFit 2C RIE/RIC receiver wires replace the SureFit 2B RIE/RIC receiver wires. The SF2C receivers can be used with all the existing 3pin aids (Linx2, Linx3, Linx Quattro, Enya, Vea) but they will require new "1-rung" domes. The SF2C require "1-rung" light grey domes whereas the SF2B receivers require "2-rung" dark grey domes.
Replacing ReSound SureFit 2C RIE receiver tubes is not difficult just a bit fiddly, make sure you know what you are doing before you start!
Please remember that RIE/RIC receivers have a wax filter which needs to be regularly replaced - when it gets 'bunged up' with wax the sound gets blocked!
