You will absolutely see the things I described happen (assuming you don't pass away too soon).
If I had to choose between the two, I'd take sight over hearing any day. I wouldn't take invasive surgery for a hearing device that connected me to my friends when a phone works just as well. But the ability to send/receive exact visuals to/from self/others would be an awesome thing.
Also, partial blockage of vision by the gizmo will be worked around. They'll splice/jack the feed straight into the optical nerve behind the retina at some point. It's going to happen. Completely obvious in my opinion. The good thing here is, it's going to happen soon. I should see this in my lifetime.
Humanity will be profoundly changed. It will be interesting and frightening for those of us who were born before these things but for those born in that time they won't think twice about it.
