You guys complaining about price really know fsckall about costs do you?
The Samsung equivalent to these (the Gear IconX) costs $199.00 and is in most ways a substantially inferior product (much shorter batter life, shorter BT range, doesn't have the easy Apple set up).
What you guys don't seem to understand is that most companies have hit their competence wall at making modern phones. Even a phone like the Nexus 5 has some serious design flaws in it (which I'm afraid I can't discuss because I heard in confidence); not "it does not work" flaws, but issue around heat flow that mean it has to run at below ideal performance. A PHONE already has to get the electronics, the thermals, and the radio issues all lined up correctly, and that is getting harder and harder.
Move on to watches. Most of the initial watch companies have given up. The only three serious contenders left are Apple, Samsung and Garmin. (And how long do you think Garmin is remaining with us...). Google has dreams of a Pixel Watch but I don't know who they think will make it for them. Everyone else in this space is making much simple fitness bands, and there's no evidence that Withings or Fitbit or whatever can make the quantum leap to the complexity of an Apple Watch class smart watch.
OK, now move from wearables to hearables. The volume is even smaller. The wireless is even tougher. The health constraints are even harder (no-one wants a device that can somehow hurt or infect your ear or fall apart inside it). There have been a number of kickstarter projects in the hearables space (around 20 or so). Pretty much all have failed, most (alll?) of the those that didn't (Earin and Bragi are the only ones I can think of) have been delayed. Even APPLE had to delay. These are HARD HARD HARD things to design and manufacture. Let's be a little realistic about price!
If you don't want to pay $159 (or Samsung's $199, or Bragi's $245 or Earin's $189) then buy over the ear BT headphones. There is a REASON those are so much cheaper and have so many more brands...
