I'm glad I have better/supportive friends. They don't have much experience with terminology aside from the usual advertised Treble and Bass. I gave some of them a listen to my portable cans JVC HA-S500 and the indoor Goldring DR150, all had good feedback. Most of them will comment about the bass on the S500, how low and prominent they were. I've slowly mentioned and taught them other terms like soundstage, clarity, instrument separation, etc. They always seem very interested because all of us have different interests and hobbies (one guy is a wall climbing freak, some smoke vapors/e-ciggs, some mod their import cars, some gaming rigs, etc) so we understand what means more to each person.
No successful converts though.
