How important is weather or water protection for your headphone?

Protection from water & weather is extremely important depending on what your usage is. For example if you need something purely indoors & calls you might not protect from weather & or water. On the contrary, if you are buying this for your work out please check the IPX rating of your headphones. Check for IP ratings if you need your headphone to be waterproof & dust proof.  Also read the specifications of headphones where products are mentioned as splash proof as opposed to waterproof, both cater to different requirements.
