Bose’s rumored QC 35 II noise-cancelling headphones are rumored no more: Bose made them official today, revealing the update to the company’s popular QC 35 premium noise-cancelling cans.

Google worked with Bose to create the new headphones, the company explained in a new blog post, helping to “optimize” the audio accessory for Assistant, Google’s virtual helper software for iPhone and Android. The headphones have a dedicated Assistant button, which users can push to call up the voice-based companion whenever they want.
