Momentum true wireless from Sennheiser are interesting. The touch controls are insanity. Literally, the guy handed me a newspaper-sized instruction card of all the different gestures. The silicone ear cups lacked isolation—as all IEMs do, next to KSE1500's black foam tips—and all things considered, are a crippled middle place between AirPods and Shure's Ultima. The AirPods are the most convenient ever made, and have great quality sound for phone calls and podcasts. When I listen on my bicycle, the background noise - which I want, so I know if a car is coming - is loud enough that any greater SQ would be lost on me. KSE1500 sits at the summit of IEM isolation and SQ, and with the micro to lightning is only somewhat awkward to carry in a pocket while walking. (You must leave it in your pocket, though. Texting with the dac/amp attached is dreadful.)
True Wireless are for sure a great option for many people who don't want to buy both the $159 and the $2999 toys. You can attach 3rd party tips, I hear, and the sound appears to be pretty good. But my use cases are peculiar. I am looking at the LCD-4, though, or 4z, with some interest.
51 days in Europe. Am I insane, or just a teacher?
Yes.
