will these tips fit the GR07??
Yes, they fit. They look and feel exactly like the medium foams that come with the SoundMagic PL50. Except these are de-cored. Because of that, they didn't fit on my PL50 like the seller said they would. They fit on large nozzles though since there's no inner core with these foams. So far, they fit on my GR07, TF10, CKM99, and Brainwavz Beta. Very comfortable.
