I'm sorry. Did I imply that the ER2XR would replace the BL-03? I want something that can be used while working with all sorts of power tools and just riding noisy vehicles. I find out at times the BL-03 doesn't have enough isolation for the task. The WHOLE point of the ER2XR is that is an earplug that can also play music. The BL-03 fundamentally doesn't do this very well due to the vented nature.I found the bass of the ER2XR disappointing compared to even the BL03. You might do better just getting some good-fitting foam or hybrid tips for isolation.
I'll probably also want to buy some earmuffs to wear on top of the ER2XR.
