Hello everybody, I've recently bought the GR07 MK2 and love it. But I'm yearning for something with more bass to compliment the MK2, I bought the BE version hoping it would satisfy my needs but I find it lacks impact or thump. Guess you could say I've been spoiled by bass heavy earphones. I used to own the Klipsch S4 and Senn CX300. Basically I want something with heavy impact. I've heard the JVC fxz200 have killer bass but I believe its over $200. By the way, what is the difference between sub-bass and mid-bass; I have been perusing these forums lately and have come across these terms but am clueless to what they mean. Any advice would be well appreciated.
