Hey guys sorry for the delay.
Because there have been a lot of questions about how the Nano should sound when in use, I want to address it. I verified with our team that the Nano is not noiseless.
Typically you will hear the Nano working when you are standing close to it. However, it should sound more like white noise in the background when you are talking, when there are other sounds in the same room, or if you are not near the Nano. Note, the Nano does not share the same noise as our older models do. Also, the Nano should not be disruptive or produce loud, unbearable or high-pitched whistle noises.
Below is a video that will give you an ideal of what your Nano might sound like. Please note, this is how it sounds on a phone mic when relatively close to the Nano. Sounds will be a little bit different in real life. If you have additional concerns or questions, please feel free to reach out to our customer success team at firstname.lastname@example.org
