I would also go for the GR07BE. They are back on sale at LMUE.
Are they gone at LMUE now?
I saw it just 5 days ago on their site, now its not there. Maybe they are restocking. Best to check with them.
Shure 215 is bassy, mids are okay, but lacks treble extension and details. Seperation is not good also. Good for rap, some rock and some bassy music. Very sturdy. Good comfort and isolation. I don't know the others.
