Strongly disagree here. I’ve been using high end IEM’s for two decades. With other models such as Etymotic, Shure, and the cottage industry that developed chasing that basic design, the user must go through contortions like wetting and twisting the rubber tri-flange tips typical of Etymotic back and forth until they sit extremely deep in the ear canal or there is literally zero bass to the sound. Or with the standard foam Shure tips you must get the largest tip that will fit, compress it with your fingers, and press/twist it into your ear with a decent amount of force else there is little bass AND there is zero passive noise suppression. I’ve owned multiple pairs from each of these vendors and others, and spent thousands of hours using them on flights.
The APP’s in comparison require you to place the earphone in your ear and twist it very slightly towards the back of your head. There is no pressure required, and the tips never protrude very far into the ear. The active noise cancelling works extremely well even as they loosen such as when running with them, and the sound does not vary much regardless of how tight they are in place.
The fit test clearly changed its behavior at one of the software releases in December and it’s strongly coloring user perception. Yes, the ANC changed a bit too with one of the firmware updates, but all the complaining about the fit test is likely to just drive Apple eliminate it entirely in the future as they can simply handle this silently in the background.
If there is a huge selection of 3rd party tips already available I fail to see your point of outrage. Limiting themselves to one of the “standard” tip designs would have been extremely limiting to Apple’s overall design of this product, especially as the typical IEM uses a narrow stem and relies entirely on passive noise reduction. Fine if you are making a $25 knock-off. Not at all suitable for a clean-slate Active cancelling solution with a huge budget.
