On the grey housing of the speaker wire blue denotes a left wire, red denotes a right wire. Labelled on the speaker, the number is the size of the wire and the letters denote the power level (xS for standard and xP for power) e.g. a size 2 standard wire for the right ear would have a red label on the grey housing and you would see 2xS.
Please contact us if you are unsure of which size/power level to order.
