I'm lucky, neither of my ears has any dips or other problems, but my wife needs a hearing aid for one ear, and this one actually has presets for conversations, watching TV, talking on the phone and what not, and you can even create your own presets with the accompanying phone app.
It's amazing that these tiny in-ear headphones can communicate with a phone via Bluetooth.
