If you are, you might want to consider this law regarding listening to music or communications systems, which includes motorcycle communications systems.
Basically, the use of any music or communication system with headphones or earphones is illegal. That means ear-buds for listening to music, or even speakers inside your helmet for talking to pillions or to other riders, is prohibited. You might want to consider this before riding in Spain.
This is the relevant part of the law, translated by Google…..

A few years back, a friend and I were riding through Spain and we were using a bike-to-bike communications system to talk to each other as we rode. Early one morning, we were stopped by the Guarda Civil who, having seen the cables leading into our helmets, told us we must disconnect these and stop using them. They were very polite and told us it was illegal and didn’t prosecute us and we clearly were surprised by this unusual law.
