Nah, you're not alone. Usually I can see sense in premium products, even ridiculously expensive statement pieces because they bring something extra. Just this morning I was drooling over Sammy's silver housing Zombie with black rhodium plating. It's bonkers, but it's like jewellery or a fancy watch. There is craftsmanship in there with an enduring quality. With the SE6 I really struggle to see sense. They are just silicone CIEMs with nothing beyond the sound to justify the price, contrast that with the Erlkönig and the value proposition is completely different. Moreover, the silicone material is simply not the most durable, so they might not even last that long. And then there is the note by SE that you shouldn't use aftermarket cables because they will degrade the sound, while showing off a cable with cheap memory wire. At least they could have gone for a cable that has some thought into its ergonomics.
It simply doesn't come across as a premium product, so it only has the sound as its main selling point and you can't ever demo it. So they expect you to trust them (or any impressions you find) blindly, while also refusing to offer a reshell service to anyone other than the original customer, which means selling them on is impossible. So essentially they are extremely expensive, disposable IEMs you have to buy blind. To the best of my abilities, I can't see the sound ever being worth it.
