The closure isn't coming for lack of trying. In an interview with Wired, Doppler chief Noah Kraft has revealed that the company held preliminary acquisition talks with Amazon, Apple, Facebook, Google and Microsoft. When those didn't pan out, Doppler didn't have many options. It had sold just 25,000 earbud sets, which clearly wasn't a sustainable business. The company had pivoted to focus more on hearing health (it even helped pass a law that enabled over-the-counter hearing aid sales), but that didn't matter when there was no one to fund this change in direction.

And as Kraft explained, the very act of starting a hardware company was Doppler's mistake. "We shouldn't have done that, he said. It's not hard to see why. While the smart headphone market was largely new when Doppler got started, things got very crowded, very quickly. Between Apple's AirPods, Samsung's IconX and Google's Pixel Buds (among others), Doppler was trying to compete with smart earbuds that had much stronger brand recognition and access to resources that a startup just couldn't match, such as AI assistants like Siri or Bixby. Its consolation prize is that it helped start the trend toward smart, completely wireless audio -- the next time you're talking to your earbuds, you'll know who to thank.
