I love my M80 but i've been using it for quite a long time so i just thinking maybe now it's time to look for a new headphone. I listen to all kind of music but most of them are old Pop/RnB/Ballad. The GR07, from what i've heard, has the M80's sound, but better in some points. I'm happy with my M80 but sometimes i just wish it had more bass (i'm an basshead). So should i exchange it? And is it worth to exchange?

The change in paradigm from headphone to IEM does not lend itself nicely for comparisons against bass quantity. Both have a slight mid-bass emphasis but relatively, the GR07 isn't a huge step in sheer bass. Might want to rethink your plan entirely. Perhaps a new phone or some other bassier IEM.

What are you using as source?
have you thought about an Headphone amp? I Think the M80's can pump out a quite good amout of Bass...
