When I ask Siri to change the volume, I get no audio feedback from Siri. The volume does change but I don't get a voice telling me it has. Is this normal?
It depends on whether you have audio playing, which makes sense. On mine, if something is playing, there is no voice feedback. If there is nothing playing back, you get "OK, media will play louder/softer".
There's no audio feedback. That plus the delay in the volume kicking in leads to uncertainty.
It's really annoying there's no control on the buds themselves, and that Apple basically makes you buy a $400-minimum volume control for your wrist if you don't want to fish out your phone every time.
I really don't care so long as it works. When the internet is spotty (especially at work where I'm on a lousy DSL wifi connection and one or less bars of LTE) sometimes I get 'One moment' and it works....five minutes late.
