On the 16/48k and 128K the type of mono sockets used will only contact the tip and ring of the stereo jack plug, grounding the ring (right hand audio channel) and leaving the sleeve not grounded. The usual symptom of this is that the signal reaching the Spectrum is far too low to load.

Using such a cable with the +3 is even worse because while the right hand channel is connected to the EAR input, the left hand channel is connected to the Spectrum's output. Again this is unlikely to cause permanent damage, but connecting two audio outputs to each other is generally a bad idea!
