You have my sympathy. I've been waiting some decades for a real solution to this problem. Unfortunately, the physics involved and available so far have proven fairly intractable. (I've tried variations of most of what's been posted here. And I can't use music as a block -- too distracting.) If someone really takes on this problem, my anecdotal experience is one of having encountered a significant number of people who would buy in. People looking for an Apple-like experience: High quality manufacturing and performance combined with a simple choice or set of choices. This includes ergonomics; for example, in addition to not providing complete attenuation, tightly sealing over-ear muffs can become extremely uncomfortable, tiring, and physically distracting during extended wear.
