I hate the fit of the MW07 because they have a VERY shallow fit and feel like they are going to fall out all the time. And I have tried many different tips and the stupid wing things and nothing helps. It is very frustrating because I keep trying to push them in deeper but the housing prevents the tips from going fully in my ear to get a good seal. However, I will say they have the best sound I have heard in a TWS IEM. (If you can get a good seal)
