Here is my situation. My dog destroyed my Etymoic headphones. They fell on the floor and he thought they were a new kind of treat. :(
I listen to many different types of music, e.g. acoustic guitar, blues, country, classical, jazz, rock. I listen neither to rap or opera.
I have a used Mapletree Audio Design Ear Four Combo Headphone Amp / Line Preamp that is on its way to me; a pair of Harmon/Kardon CL headphones; Apple standard in ear headphones for the iphone 5c
