I think those kind (of) headphones work best when you have a steady distracting noise, but not something with stops and go's. I bought the cheapest
musician earplugs and they worked fine. The problem with this solution, is that thoughts and images proliferate...wildly, IME. You may overcome this with out-loud Mahasi noting, which could help you during the M&B, A&P and DN, but perhaps not in EQ.
