The really cool thing is if you connect it to a Bluetooth headset that's A2DP compliant all the sounds, including clicks and notifications, come through the headset.
It is like an electric car. People get spooked when something does not make a noise like they might expect. We equate noise with working. You get in an electric car, turn on the ignition and nothing make a noise. It is amazing how spooky that can feel, especially when you get close to someone not paying attention and honk the horn.
