VERY messy and confusing? There's one over-the-ear, one with tips, one base with ANC and one without. That's "very confusing"?Having two separate base models on top of a Pro and Max version makes the AirPods lineup VERY messy and confusing imo. Also, you can almost always secure the Pro 2s with USB-C at most retailers for $179 anyway so what's the point of the ANC model?
The open-ear model is for people who don't like tips. My wife and I had Pros and sold them because of the tips. Not everyone enjoys the feeling of rubber tips sliding in and out of your ear, and not everyone's ear shape is conducive to them staying in.
I don't think having one additional model takes the lineup from acceptable to "very messy and confusing"
