Weird how the lack of (passive) noise cancellation is considered a negative, for me it's the feature why I'm getting these to replace the 1st gen airpods besides my Airpods pro. A lot of passive noise cancellation would totally defeat the purpose for me. It's also the differentiator between the Pro's and the normal ones, you want noise cancellation, get the pros.
Well, the pros also have active noise cancellation as well as a transparency mode, so there would still be a big differentiator between them even if the Gen 3 had silicone tips. I'm confused why you say that a better seal between the Airpods Gen 3 and your ears would "defeat the purpose" for you. What do you view their purpose as?
